What's the experience of working in State Grid?

Most operators working in the traditional power grid will say something like "like migrant workers, living in the station and being looked down upon by others is not so good". The traditional operation and maintenance form of power grid companies is time-consuming and laborious, and its efficiency is low. With the birth of big data and artificial intelligence technology, smart grid was born, which can reasonably improve operation and maintenance efficiency and reduce costs.

Taking the substation as an example, from the traditional substation to the intelligent substation, its differentiation is mainly divided into three aspects:

1. primary equipment intelligentization: the intelligentization and informatization of primary equipment is the key to realize the informatization of smart grid. By using the standard digital and information interface, the intelligent primary equipment integrated with online detection, measurement and control protection technology can meet the information flow requirements of the whole smart grid. The equipment layer of smart substation inherits all the functions of the process layer and interval layer of traditional substation.

2. Equipment condition maintenance: On-line equipment condition detection is a brand-new function, which can be said to be one of the core differences between smart substation and traditional substation. Intelligent primary equipment can judge the running state of primary equipment through advanced state detection means, reliability evaluation means and life prediction means, analyze the fault of primary equipment when the running state is abnormal, judge the location, severity and development trend of the fault, thus identify the early signs of the fault, and carry out maintenance before the equipment performance drops to a certain extent or the fault will happen according to the analysis and diagnosis results.

3. Networking of secondary equipment: the secondary equipment in the substation is connected through high-speed network communication, and there will be no repeated I/O field interfaces of conventional functional equipment, so that data and resources can be shared through the network.

Substation is the core link of power grid. The appearance of smart substation has changed the traditional substation operation and maintenance mode, realized the intelligent and green transformation of substation, accelerated the transformation and upgrading of "unattended+centralized control" substation operation and maintenance mode, and promoted the development of smart grid. Promoting the construction of centralized substation control station can speed up the transformation and upgrading of "unattended centralized monitoring" substation reform mode, greatly improve the intensity of equipment monitoring, the fineness of operation and maintenance and the degree of production informatization, and completely solve the problems of low quality of substation operation and maintenance and insufficient number of personnel.

Hajto wave. Build a lightweight three-dimensional visualization scene, build a dynamic digital substation model and a digital double substation visualization system. Multi-dimensional presentation of substation operation and maintenance scenes, real-time monitoring of substation operation status, and interconnection of operation and maintenance equipment, control system and information system. Strengthen the whole state perception and control of substation equipment, improve the safety production support ability of substation, and improve the lean management level of operation inspection.

By expanding the scale of substation management, diversification of management tools, quantitative display of information management and data management, it supports the deep mining and intelligent analysis of substation multidimensional data. The actual production business is seamlessly integrated into the platform, which makes the daily management tasks standardized and automated, and the enterprise intelligent and professional management.
