How to do well the operation and maintenance management of substation

How to do well the operation and maintenance management of substation Abstract: Substation is a very important part of power system, so it is particularly important to do well the operation and maintenance management of substation. There are not only many technical and complicated things, but also some odds and ends in power execution, maintenance and management, but we must not be careless in the whole management work. This paper expounds the requirements and management measures for implementing the maintenance management of substations, and probes into the safety responsibilities in implementing the maintenance management.

How to do well the implementation, maintenance and management of 10kv substation —— Analysis on the importance of construction safety management of 10kV distribution network project

10kV distribution project is an important part of distribution network project in China. Construction safety is very important for distribution network engineering, and construction safety management has also become particularly important. On the one hand, construction safety management can strengthen the safety awareness of construction workers, and scientific safety management can minimize construction risks and ensure that construction workers have a relatively safe construction environment. On the other hand, construction safety management can ensure the relative safety of building materials and construction equipment. Building materials are the foundation of distribution network construction, and building equipment is the necessary component and hardware condition of the project. Once there is a problem, the whole project construction will not be carried out smoothly, delaying the overall progress, reducing the quality of project construction and causing many adverse effects. Construction safety management can effectively solve these problems, which can not only ensure that the quality of construction materials meets the construction requirements, but also ensure that the construction equipment is in a safe and available state, thus ensuring the smooth development of the distribution network project. In addition, more importantly, construction safety management can effectively eliminate potential safety hazards in construction, and these potential safety hazards are likely to cause safety accidents and cause incalculable losses under the action of external conditions. Construction safety management can eliminate these hidden dangers in the construction process and ensure that the completed distribution network project can be put into normal use.

Work and Safety Management of 2 10kV Substation

2. 1 The device shall be inspected regularly.

The safe and stable implementation of substation equipment can not be separated from regular inspection, and it is also necessary to regularly inspect all levels of equipment to fully grasp the implementation status of equipment. The regular inspection of substation mainly includes: lightning arrester inspection, battery measurement, switch hydraulic oil pressure inspection, etc. By sorting out and analyzing the inspection data, the execution state of the device can be correctly judged, thus ensuring the safe execution of the device.

2.2 Strengthen the safety education and training of substation management personnel.

Substation managers are the main operators and system executors, and their professional level and safety awareness will directly affect the quality of substation safety management. The characteristics of substation implementation are that there are many maintenance equipment, which are prone to anomalies and obstacles, complicated and boring work, and substation managers are easy to slack off. Therefore, any irregular behavior in substation may cause power grid failure and affect equipment safety. Any misjudgment and misoperation of substation personnel will cause different degrees of safety and economic losses. Therefore, it is necessary and imperative to strengthen the training and safety education of substation personnel. Let's discuss it from two aspects: operation skill training and safety awareness education.

2.3 the use of substation equipment processing

Emergency drill is a management method that takes into account unexpected situations. In the face of sudden emergencies of substation equipment, orderly organizing various emergency treatments can help substations minimize the losses caused by such accidents and ensure the safety of relevant staff. Before the emergency drill, the substation staff should be given a systematic and comprehensive knowledge explanation. Let the staff in different positions have a more comprehensive understanding of the relevant power transformation and distribution devices, so as to deal with emergencies in time. Emergency drills should be based on the principle of "safety first, prevention first" and improve the ability of relevant personnel to analyze, judge and deal with emergencies through drills. For example, when dealing with the emergency of substation equipment, all staff should wear insulating materials, do a good job of safety isolation from the outside world at the scene of the accident, and notify relevant departments to repair the equipment in time.

2.4 do a good job of inspection.

The management of substation equipment can not be separated from the inspection work, so as to prevent accidents from the source. The inspection work is mainly divided into two aspects: on the one hand, it is the inspection of the daily management of managers. This patrol is mainly to supervise the management of managers, effectively implement their management responsibilities, correct the improper management of managers, and avoid substation safety accidents caused by human circumstances. Another aspect of patrol inspection is the inspection of substation equipment, whose significance is to monitor the substation equipment itself and its execution environment irregularly to prevent substation accidents caused by substation equipment failure. Of course, according to the different equipment used in the substation, the inspection work is generally different. Generally speaking, the following inspection methods can be worked out according to the different equipment of specific substations. The first is the way of daily inspection. This patrol mode is mainly aimed at some important substation equipment and substation network. According to a certain sequence and process, patrol personnel can bring relevant detection devices, or check, judge and record the working conditions of substation equipment by means of smell, touch and hearing. The second kind of patrol is regular patrol. The frequency of this patrol mode is generally once a week, and its key patrol direction is the working attitude and working method of managers, which promotes the substation managers to be highly responsible in their working attitude and scientific and rigorous in their working methods.

2.5 do a good job in lightning protection measures

For 10kV lines that are vulnerable to lightning, lightning protection lines should be set in heavily mined areas and particularly important 10kV overhead lines. When 10kV lines intersect with each other or with weak current lines such as lines with relatively low voltage level, radio and television lines and communication lines, reinforced concrete poles or towers at both ends of the intersection shall be grounded regardless of whether lightning wires are erected. Perfect lightning protection measures can greatly reduce the risk of lightning penetrating the distribution network system and effectively ensure the construction safety of the distribution network project.

2.6 Pay attention to the protection level and protection level of 10kV substation.

In order to ensure the safe implementation of 10kV substation, it is necessary to pay attention to improving the equipment level of the newly-built substation, and to configure comprehensive safety protection devices in the substation to improve the safety protection level of 10kV substation and the safety implementation level of 10kV substation. For example, on the basis of current quick break and overcurrent trip adopted in 10kV substation, it is necessary to pay attention to protection measures such as low-voltage lockout and time-limited disconnection, so that 10kV substation can better adapt to the change of current load in 10kV substation. At the same time, the current technology is actively introduced in online execution to improve the efficiency of state analysis and evaluation of distribution equipment, thus improving the safety maintenance efficiency of 10kV substation.

2.7 do a good job in the management and maintenance of 10kV substation.

Doing a good job in the supervision of 10kV substation is of great significance to the safe use of 10kV substation. During the line supervision of 10kV substation, relevant departments need to strictly supervise the line according to the system. Arrange personnel to patrol the 10kV substation regularly, record and report the problems or potential safety hazards found in the safety implementation of 10kV substation in time, and manage and maintain the line reasonably. At the same time, the lightning protection devices along the 10kV substation should be inspected in lightning-prone areas or before the thunderstorm season, and the insulation resistance and power frequency discharge should be regularly detected at ordinary times to improve the lightning protection capability of the 10kV substation, and the lightning protection devices with problems should be replaced in time.

Equipment is the foundation, and management is the key to the normal operation of substation. In the specific management work, it is extremely important to explore a set of systematic management methods for the safe implementation of substations. At the same time, the management of substations should not be limited to relevant management departments, and the staff of each substation should take the initiative to become the protagonist of substation management. Only when everyone participates in the management work can the management work be more efficient and rigorous. Only by doing a good job in substation management can we better deliver safer, more stable and more economical electric energy to users and enterprises themselves and promote social development.

How to manage the defects of substation equipment (Laibin Xincheng Power Supply Company, Laibin 546200, Guangxi) Abstract: The defects of substation equipment are hidden dangers in the safe and stable power supply of power grid, so the management of defects is particularly important. The management of defects should not only focus on the discovery and elimination of defects, but also change consciousness and orderly control the process. According to the above understanding, some constructive suggestions are put forward for the management of substation equipment defects. Keywords: substation; Defects; Security; Process; Excluding Chinese classification number: TU473. 1 document identification number: A document number:1671-8089 (2012) 07-0060-02 substation is related to the safety and stability of power supply for thousands of households, so the safety of substation is very critical. The security and stability of substation power supply are affected by many different factors, including the technical maintenance of substation, the quality of power carrier and substation equipment. Among them, the implementation of substation equipment has a direct impact on the safety production of the whole power. Once the substation equipment fails, the power equipment will be lost and the power supply will be unstable. In addition, the whole power supply system may be disconnected, and there will be a large area of power supply paralysis. To maintain the safety of substation equipment, besides routine maintenance, it is also necessary to check and eliminate the unsafe conditions of power supply equipment in time, eliminate defects at an early stage, minimize losses, and escort safety production. First, the problems existing in the management of substation equipment defects At present, in the daily implementation of power supply enterprises, a key aspect is the effective management of equipment defects. The defect management of power supply equipment plays an important role in the safe and stable operation of the whole power supply network. Due to the rapid development of power grid and the complex distribution of urban power grid, there are more and more defects in substation equipment. If we only use the original management mode to deal with these new problems, the efficiency is relatively low. In the current substation management, there are mainly the following problems in substation equipment defect management: (1) Lack of defect management plan. In the past, the defects of substation equipment were all found and eliminated, and there was no reasonable overall planning and regular inspection and monitoring, which led to the relatively passive management and the inability to find and deal with defects in time. On the one hand, there are defects in the process and means of equipment defect management, which affects the reporting and confirmation of the whole defect, and the process of elimination often cannot play its due role. (2) The responsibility system for defect management is not implemented. The occurrence of defects was not reported to the responsible person in time, and the daily implementation of substation equipment did not carry out the responsibility of inspection, which led to the openness of the whole management. Therefore, the defect management is not detailed and specific enough, and the faults of substation equipment cannot be eliminated as soon as possible. (C) The lack of reflection and discussion on defect management eliminated the defects of substation equipment. After troubleshooting, the whole substation did not further summarize and reflect on the causes of defects, and did not systematically reflect on many defects. It is also a deficiency in management to grasp the defects of various phenomena to make judgments. We can't classify all kinds of defects, which will affect the next defect inspection and timely troubleshooting. (D) Lack of flexibility in defect management This is to talk about the planning of defect management, because some substations have corresponding defect management systems, but the implementation of the system is too rigid, which affects the play of the role. Because the occurrence of faults is not necessarily a common pattern. After the scheme and process are formulated, the implementation is not flexible, which affects the timely troubleshooting of some substation equipment. The above four aspects are some common management problems of substation equipment defect management, which affect the effective play of substation equipment defect management. Two. Constructive Suggestions on Defect Management of Substation Equipment Based on the above analysis, some problems existing in the defect management of substation equipment are analyzed, so to deal with this problem well, we must start from two major sectors, one is to change the management concept, and the other is to refine the whole process of defect management of substation equipment. The equipment defect management process includes six links: discovery, reporting, acceptance analysis, processing, acceptance and termination, and forms a closed-loop management according to "discovery → reporting → acceptance analysis → processing → acceptance and termination". In the management of substation equipment defects, the management team should change their ideas, not just stay at the implementation level of the process, but should refine and reflect on the process. The equipment defect manager who implements the process should be flexible in handling all kinds of emergencies and be able to make the fastest and best solution according to the actual situation. All these require management team members to be familiar with the power grid, have a specific understanding of substation equipment and have a strong sense of management. Let's talk about another big aspect, some details of some processes in closed-loop management of substation equipment defect management. (I) Discovery of Substation Equipment Defects Generally speaking, the discovery of substation equipment defects can be divided into pre-fault discovery and post-fault discovery. After the failure, it can't meet our management requirements, because it has caused losses, and after the failure, it mainly depends on the experience and professional knowledge of substation technicians. This paper focuses on the discovery before failure. The discovery before failure can be divided into the following three types: the first is that the defects of equipment are discovered during maintenance. For example, the marking of oil and the power failure test of main transformer found that there was no oil level in the casing. These problems were found through maintenance. The second one was found during the inspection. For example, there is a small amount of oil leaking from the hydraulic supply cylinder of the substation, which is a general defect. However, through repeated inspection, it is found that oil leakage has developed into oil leakage. Therefore, the inspection can prevent the accident from expanding in time. The third is to find the defects in the operation. This mainly requires the operator to pay attention to some abnormal phenomena, such as abnormal sound of transformer and whether the instrument is abnormal. , so as not to miss the opportunity to troubleshoot. (2) The classification and report of substation equipment defects should be analyzed together. First of all, the defects of substation equipment should be classified according to the severity of its danger and the time when it may have a large-scale impact. Generally, it is divided into emergency defects, major defects and general defects, which are easy to master and sort out and can be solved together. Attention should be paid to the report of substation equipment defects, which is accurate and timely. The accuracy of defect report refers to the scope and severity of the impact on the defect, as well as a reasonable estimate of the destructiveness of the defect, so as not to exaggerate the seriousness of the defect, and not to artificially reduce the risk of the defect because of fear of taking responsibility. The timeliness of defect report aims to gain time for troubleshooting in time. Some defects may not be as simple as apparent judgment, so timely report is necessary. When reporting, it is necessary to distinguish the responsible departments, report the corresponding defects to the corresponding responsible departments, and let the subordinate departments deal with them in time. (III) Analysis of Equipment Defects in Substations After the equipment defects are reported to the subordinate departments, the substation shall hold a weekly equipment safety meeting to analyze the related equipment defects in the past week. The analysis items facing the problems here should include the following basic contents. The first is the possible harm to the implementation of equipment in substation after the failure of equipment defects. This analysis and inspection work mainly has two functions. One is to sound the alarm for the daily inspection and maintenance of substation equipment. Equipment managers should have the sensitivity to find these defects and be responsible for reporting them after finding them. The other is to predict the possible dangers of devices, which is convenient for more accurate classification of device defects in the future. The second is to analyze and summarize the types of defects and analyze the possibility of these defects. For device defects, we should have inductive thinking, compare defects with previous defects, classify common defects in time, share treatment methods with technicians, put forward more operational and simpler corresponding defect solutions, and even form written materials to facilitate internal learning and induction. (IV) Elimination of Equipment Defects in Substation The elimination of equipment defects is the ultimate goal of equipment defect management in the whole substation. When eliminating equipment defects, we should not only eliminate emergency defects that have been seriously threatened, but also eliminate other general defects. We should not only find faults first and then eliminate them, but also pay attention to the combination with daily inspection and maintenance. If the task of eliminating defects requires a power outage, it is necessary to avoid repeated power outages and try to avoid power outages to reduce the impact on users. Eliminating defects should start with daily management, and finally make power supply benefit more people.

How to do a good job in special management of substation implementation, improve inspection efficiency, report defects in time, and do a good job in regular switching and temperature measurement; It is suggested to implement the installation Commissioner and substation Commissioner; Do on-site inspection, accident prediction and anti-accident drills every day;

How to do a good job of substation analysis is a complicated job, especially after the unattended transformation of substation, the duty mode has changed greatly, which has higher business requirements for managers. As an executive, Xiangtai Electric reminds us not only to understand the basic principle of the equipment, but also to remember all kinds of rules and regulations, not only to do a good job in the daily inspection and switching operation of the equipment, but also to learn basic accident handling and abnormal analysis, which requires the executive to strengthen business learning.

How to manage the hydropower station (1) well depends on safety education.

Establishing a firm sense of safety is the basis and key to ensure the safe production of hydropower stations. In recent years, we have always put safety production management in the first place, put safety education into practice, and changed every employee from a passive "I want to talk about safety" to "I want to talk about safety". Specific measures are as follows. 1) Through positive education, negative education, reward education and punishment education. Positive education is to set an advanced personal example and take advanced personal deeds as an example to make employees consciously increase their awareness of safety responsibility. Negative education is to use common accident cases as teaching materials to let employees remember the lessons of blood. Reward education is to work conscientiously and responsibly, obey the rules and discipline, vigorously publicize and commend, and reward and reuse; Punishment education is to punish those who are negligent, lax or have "three violations" accidents in strict accordance with relevant systems, which makes employees feel heartache and touches their souls. 2) Make employees familiar with the production process and understand the importance of safe production through training technology. Many production equipment involved in the work of hydropower station are unfamiliar to a new employee, but not paying attention to some details or being careless in the production process will cause serious accidents. Therefore, it is necessary to conduct special safety education and training for new employees. On the one hand, they can get a preliminary understanding of the production process of hydropower stations, on the other hand, they can deepen their understanding of safe production.

(2) Employees' skills should be in place.

1) Conduct pre-job training and follow-up training for new employees, so that new employees can get familiar with the working environment and technology as soon as possible. The specific contents of the training include: learning structure, implementation principle, device efficiency, technical status, operation technical points, safety production process, specifications, etc. Through more detailed training, enter the probation period, probation period, or check the training content irregularly during the training period. Finally, after the probation period expires, you can only work after passing the unified examination. 2) Conduct technical training for all employees on a regular basis, and constantly update employees' mastery of new equipment and skills. Due to the continuous research and development of new equipment and technologies, it is not good for all employees to master new technologies. Therefore, it is necessary to make full use of the available rest time of administrative classes, zero-point classes and four-point classes, and organize all employees to concentrate on learning and training new technologies. By the deputy director in charge of new technology, starting from the basic theory and combining with the actual situation of hydropower station, reasonable teaching is arranged, so that workers can learn and master new technology from the aspects of unit structure, efficiency and working principle. Employees are given a unified examination twice a year, and the examination results are directly linked to the year-end assessment, which greatly promotes the enthusiasm of employees to learn new technologies and master safety production.
