Safety measures for flood prevention in hydropower stations (5 general articles)

?The emergency plan is to ensure our life safety and health. When a sudden accident occurs, people usually prepare a series of emergency plans in advance. The formulation of emergency plans can control the spread of the accident in a timely manner. How can we write a good emergency plan? The following is the "Safety Measures for Flood Prevention in Hydropower Stations (5 General Articles)" that I have carefully compiled for everyone. It is for reference only. Let's take a look.

?3. Internship content and process:

?(1) Understand the components and management plans of hydropower stations.

? (2) Understand the implementation process of hydropower station work and solutions to hydropower station problems.

When we arrived at the power station on the morning of the 9th, we were warmly received by the leaders and employees of the power station. Then, the leader told us about some conditions of the hydraulic hub, precautions and relevant regulations when entering the factory, as well as safety issues. We listened carefully and kept it in mind, because our major is electrical automation, and this time we went to a power plant for an internship. Touching anything in the power plant can easily cause safety problems. If we don't obey the command, that "electric tiger" "It will swallow up our young lives at any time.

?In order not to affect the normal training process and safety considerations, a group of more than 40 people divided into two groups and conducted training on the power station one after another. Our group, led by teacher Huang Yaoning, began an exciting trip to reveal the secrets of the hydropower station.

?We arrived at the technician's hall first, and there were three generator sets in the hall. I was very touched when I looked at these tall generator sets. I felt how great human beings are, and they can transform the power of nature into various powers that can be used by humans. Humans are truly amazing!

?I then followed the technician to the manual control room, where there were many large cabinets. Such as demagnetizing switch cabinets, excitation regulating cabinets, safety cabinets, voltage regulating cabinets, etc., I was dazzled by them. I can't help but wonder how the technician remembers so many switches! I admire them so much. Then we walked to the high-pressure room, which as the name suggests is high-voltage output regulation. Every place here is dangerous. It makes me scared to see it. I dare not move or touch it.

?Then we went to the second floor of the hall. This is the working building of the generating unit, also known as the turbine room. Water flows underneath the turbine. When the water turbine is driven to rotate, the conductor in the generator cuts the magnetic field lines to generate current. In this turbine room, I also saw many rotary switches, which are used to control the operation of the turbine. Next, we visited the high-pressure gas engine room and the pipe room one after another. This pipe room is used to transport water. The pipes are all hydraulically controlled.

The technician also led us to visit other transformer equipment such as voltage and current transformers, allowing us to learn more knowledge.

After we visited the upper part, we went to the lower part under the guidance of the technician. The rumbling sound is the main theme, and the huge water turbine is the main perspective. The pressure pipe is connected to the turbine. The pressure pipe refers to the pipe that transports water from the reservoir, forebay or surge chamber to the turbine. Its general characteristics are steep slope, high internal water pressure, and ability to withstand the dynamic water pressure of water hammer

?1. Superstructure: The superstructure of the main factory building includes each floor and its beam and column system, crane beams and frames, as well as roofs and retaining walls. Its main function is to bear the weight of equipment, live load, wind and snow load, etc., and transfer them to the base structure.

?2. Substructure: The substructure of the factory building includes structures such as volute, draft pipe and tailrace pier wall. For riverbed-type factory buildings, the substructure also includes the water inlet structure. Its main functions are to withstand water load, form the foundation of the factory building, bear the superstructure, power generation support structure, transmit load distribution to the foundation and prevent seepage, etc.

?3. Generator support structure: The function of the generator support structure is to bear the weight of the unit equipment and the dynamic load, and transmit it to the substructure.

?Reservoirs, power stations, and power grids form a complete system. The water in the Lushui River Reservoir is diverted from the waterway. The water drives the turbine to rotate, and the turbine drives the generator to generate electricity that is transformed and sent to the power grid. Due to our lack of electrical knowledge, we first came into contact with a few terms, such as water head, thrust shoe, guide bearing, etc. We don’t have enough professional knowledge. We need to strengthen our electrical knowledge. We need to expand the direction of automation wider, from weak electricity to strong electricity. We all need to master it. These are very useful knowledge.

?Finally we came to the central control room, which is the brain of the power plant. The entire power plant can be controlled here, and the precipitation in the river basin can be monitored here. You can also monitor the entire factory. If there is an emergency at the power plant. All instructions are issued here to process. After visiting the central control room, our internship ended.

?4. Summary and experience of the internship:

?The one-day production internship is over. What I saw and heard here, I think it is very important to write it down in just a few lines. It’s hard to say specifically. I really like the atmosphere of actual production. The future life should be like that, with a sense of accomplishment in work and a sense of happiness in life. It was a quite quiet land, and within a short period of time, we had become accustomed to the life here. However, we only had the opportunity to practice, but not to start operating. That was a bit of a pity, and because of this, I tried my best to ask more questions, firstly to eliminate the confusion in my mind, and secondly, to make myself feel at ease. I must go back with knowledge and insight.

?The day is indeed short, but I still have a certain understanding of the whole thing. As far as the automation major is concerned, looking at the infrastructure of the power plant, I feel that the level of automation is a bit low, and I feel a little disappointed. But at the same time, I feel a little bit pleased with myself because we have so much room to use. The control room of a hydropower plant is in the same workshop as the unit, but it is just a separate room. The control room is controlled by a computer and mainly uses relay control, which shows its degree of automation. Power plants still mainly rely on human monitoring and operation. But I think that is imperative, otherwise it will be difficult to keep up with the pace of modernization of the motherland.

?From a professional perspective, I mainly talk about the control part. The so-called automatic control means that no human intervention is required at all. The main goal of power plant unit control is to obtain stable voltage and frequency. And the controlled carrier should be the flow of water. When the water flow rate is constant, the rotation speed of the hydraulic turbine is constant, which drives the rotor of the generator set to rotate. When the rotation speed is constant, the voltage and frequency generated are also determined. To achieve automatic control, a closed loop should be implemented. I didn't understand their control idea. It seemed like it was an open-loop control. The staff set the regulator switch value based on the monitoring results to control the water flow. Because the workshop was too noisy at the time, I asked the instructor, but not only did I not hear clearly, I didn’t understand either. Later, when I visited the control room, the staff went to the site to operate the regulator based on the data on the monitoring screen. It can be seen that it is not a truly automatic control.

Since then, my internship has given me a better understanding of power plants, an attitude toward future work, and confidence in the prospects of our profession. I think this is a harvest and a successful production internship. . Flood prevention safety measures for hydropower stations (5 general articles) (Part 2)

?In 20xx, the safety production work of hydropower plants was under the guidance of the company’s leadership and functional departments, and various laws on safety production work were conscientiously implemented and executed. regulations and the company's safety management system, adhere to the safety production work policy of "safety first, prevention first, comprehensive management" and people-oriented management methods, strengthen safety production management activities and safety business skills training for employees, so that safety production work can be carried out carried out smoothly. The work of the past year is summarized as follows:

?1. Strengthen leadership and improve the management network and management organization

?In accordance with the company's Bamboo Electricity Safety Committee [20xx] No. 1 and 5 documents The spirit and requirements are: first, the factory director is established as the team leader, taking overall responsibility for the safety production work of the entire factory; the branch secretary and deputy factory director are the deputy team leaders, in charge of safety work; full-time safety officers are specifically responsible for daily safety production aspects The work safety leading group arranges, supervises and inspects the implementation of safety work at each station and team, and organizes investigations and analysis of the causes of accidents. Second, it is clarified that each station and team leader is the first person responsible for the safety of the station, and the team leader is the person in charge of team safety. The responsibilities of safety managers at all levels were further clarified, the safety management organization was adjusted and standardized, and the safety management network diagram was re-formulated due to personnel changes. Factories, stations and teams have established 13 safety management organizations and 13 safety production networks. In the factory-wide safety network, 13 people are identified as the primary responsible persons for safety at all levels, 62 full-time (part-time) safety officers, and 12 flood control and rescue teams have been established, forming a system where safety work is managed at every level and managed everywhere. Good layout. The third is to adhere to the management method of "three-level management and four-level assessment". This year, the factory and the station (team), the station (team) and the team or individual signed *** 251 safety production target management responsibility letters, and collected safety mortgages at all levels A total of more than 153,000 yuan was invested, creating a good atmosphere for production safety in which "everyone has a heavy burden to bear, and everyone has a target on their shoulders." The fourth is to continue to insist that the safety leading group hold a safety meeting every month to summarize and analyze the safety production situation of the previous month, and at the same time arrange the key points of safety work for the next month, so that the safety work is planned, arranged, implemented, inspected, and inspected. There are summaries and evaluations to ensure that safety work is truly implemented.

? 2. Adhere to safety rules and regulations, and manage in an orderly manner

? The hydropower plant conscientiously implements various safety management systems and continues to implement the "Hydropower Plant Equipment Failure (Accident) Response" Reporting System", "Hydropower Emergency Repair and Emergency System", "Responsibilities of Hydropower Maintenance Personnel", "Relevant Provisions of Hydropower Plants on Strict Implementation of "Two Invoices and Three Systems"", "Equipment Liability Accident Responsibility System and Compensation System", "Routine Inspection, Maintenance and Prevention of Hydropower Station Equipment and Facilities" "Regulations", "Routine Maintenance Work Ticket for Hydropower Station Equipment and Facilities" and other systems, based on the new problems and new situations encountered during the implementation and implementation of these systems and the safety assessment in 20xx, combined with the actual hydropower production, we will re-formulate, modify, and The "20xx Employee Safety Training Plan", "20xx Safety Assessment Rewards and Punishment Measures for Hydropower Plants" and other safety work management and assessment methods have been improved. A training and guidance group for hydropower plant employees was established and practical training was provided to employees to further familiarize them with the hydropower production process, operating procedures, and regulations such as "three regulations and ten systems" and "two votes and three systems". We have increased the implementation of the "Notice on Matters Concerning the Safe Use of Transportation Vehicles" system and insisted that each station sign a total of 75 safety responsibility letters for the safe use of transportation vehicles with employees who own motorcycles. Adhere to the regular safety meeting system, safety inspection, equipment hazard investigation, defect elimination, rectification system, accident analysis and handling system, flood prevention and rescue system and employee safety progressive system, and carry out safety assessment to station (team) teams and individuals. The factory safety team conducts safety inspections at each station regularly and from time to time, and promptly rectifies any problems found. Adhere to the implementation of the "safety deposit system", and according to the safety responsible persons at each level, the size of the safety responsibility is divided into different levels of 200 yuan, 150 yuan, 100 yuan, and 50 yuan. Collect security deposit.

The hydropower plant collects safety deposits totaling 8,550 yuan from plant members, stations (teams), team leaders and part-time safety officers, which are kept by the hydropower plant safety leading group. Each power station collects more than 8,700 yuan personal safety deposits from employees, which are supervised by each station. Keep it and return it at the end of the year according to the safety assessment score. Factories and stations (teams) have also improved a series of safety management rules and regulations based on the actual situation, including emergency repair and emergency rescue plans for personnel, equipment, and various natural disaster emergencies, so that the safe production of hydropower can be followed. , Safety management work is standardized and institutionalized.

?3. Existing problems

?1. Some employees have weak safety awareness. Although the accident rate has dropped this year, the safety awareness of a small number of employees is still poor, and the implementation of regulations and systems is not in place.

?2. In terms of management, a few power stations still have untrue records, some managers are not strict in implementing the system, fail to implement safety work in place, and fail to supervise and punish, resulting in poor performance of some employees.

?3. Some power stations still have insufficient training for employees and insufficient publicity and education on laws and regulations, resulting in repeated violations of rules and regulations by employees.

?4. Because the power stations (points) are highly dispersed, there are many problems and safety management is difficult. Some power stations still have aging equipment and many hidden dangers in hydraulic facilities. There are also some villages near the power station where electricity is connected to the machine room, seriously endangering the safe operation of the power station equipment.

?Ensure the realization of the safety goals in 20xx

?The safety goals in 20xx were discussed and approved by the Municipal Bureau Security Committee, and the goals are In line with the actual safety work of our bureau, achieving the above goals requires the joint efforts of all cadres and workers across the board. We must start from the three elements of personnel, system, and equipment, and especially solve human problems. All units must follow the principle of three-level control, from grassroots teams to stations and power supply bureaus, to formulate safety goals that are in line with the actual conditions of the unit, and call on all employees to participate and work hard in accordance with the established goals.

?20xx is the year of deepening the reform of the electric power system. We must complete the third phase of rural power grid transformation as scheduled. A series of problems such as the complexity of the county power grid, tight time, and heavy tasks are before us. Safety work is faced with It is an unprecedented challenge, but we firmly believe that with the correct guidance of superior leaders, the strong support of bureau leaders, the joint efforts of all cadres and workers, and the guarantee of various rules and regulations, the safety goals in 20xx will be achieved.

Flood prevention safety measures for hydropower stations (5 general articles) (Part 5)

? For a long time, power system accidents have caused serious injuries to people and equipment, and caused great economic losses. To this end, operating personnel must always put safety first. While ensuring the normal operation of the unit, they must promptly organize everyone to learn the electrical industry safety work procedures, safety documents issued by the group company, safety briefings and other safety-related knowledge, and enhance Everyone's safety awareness ensures the safe and civilized production of this site. We carefully conduct patrol inspections of equipment at work, report problems in a timely manner and deal with them to ensure the safe and stable operation of the equipment, and strive to complete various goals in 20xx.

? Adhere to the basic policy of "safety first, prevention first, comprehensive management" in work, further implement responsibilities, do a good job in inspections, and actively explore the establishment of a long-term mechanism for safe production. Comprehensively complete all safety production indicators issued by our station, resolutely curb the occurrence of major accidents, control the development of minor accidents, maintain the steady development of the safety production situation, and promote the work of each team to a new level.

?1. The frontline of the power plant works hard to ensure smooth and efficient operation

?Power plant production is the top priority of our station and the source of the economic lifeblood of the power station. All cadres and employees of the plant We have been down-to-earth, worked hard, and achieved good results. The specific performance is as follows:

?1. Strengthen responsibilities at all levels to ensure safe production.

?The power plant has always given top priority to production safety. After signing a safety work responsibility certificate with the station at the beginning of the year, it immediately signed a target management safety responsibility certificate with each duty, and the responsibility was assigned to the shift and the individual. In April, safety regulations and technical lessons were given to power plant employees. In May, on-site training and explanations were conducted at the power plant, and safety and technical examinations were conducted for employees in relevant parts. Those who excelled in the examinations were selected

? Strengthened investigations of downstream flood channels and upstream reservoir areas

?The Gutian River basin covers an area of ??1,325 square kilometers. Illegal reclamation and other phenomena are often found in the basin with an area of ??tens of square kilometers near the reservoir. In order to strengthen the management of the reservoir and safeguard the interests of the factory, our factory insists on conducting inspections of the watershed every quarter. In March this year, together with the Gutian County Flood Control Office, we conducted a comprehensive inspection of the first-level reservoir area watershed, and found and stopped two Reclamation behavior within the reservoir.

During each rainfall and typhoon period during the flood season, factory leaders organize relevant personnel to conduct meteorological trend analysis and implement various flood prevention tasks. During floods and rainfall, power stations at all levels will send additional personnel to the site.
