On April 28th, the State Grid Corporation pilot project “Online Monitoring and Analysis of Distribution Network Operation Efficiency†was officially launched in Xiamen, Fujian. The implementation of the project means establishing a systematic analysis and evaluation model for the efficiency of distribution network operation, and will provide supporting decision support and lean management basis for key links such as distribution network planning and construction, operation management and material procurement. Continuously improve the focus of the operational monitoring system and the level of control of other business systems.
It is understood that according to the strategic decision of State Grid Corporation to accelerate the construction of modern distribution network and the requirements of lean management of the company, the development of distribution network will realize the shift from focusing on quantity and quality to focusing on efficiency and efficiency. In this context, last year, State Grid Corporation proposed the “Online Monitoring of Distribution Network Operation Efficiency†project, and selected four cities including Xiamen as a landing pilot. The project will measure the operational efficiency of distribution network assets from a new perspective of security and economy of the power grid, and solve the key problems of weak distribution network, thereby promoting the improvement of power supply capacity, improving power supply quality and meeting the needs of economic and social development.
In November last year, the pilot project was officially launched. In the construction process of more than half a year, Xiamen Power Supply Company combined with the power grid structure and operation characteristics of Xiamen area to complete the access, matching, cleaning and calculation of data of each business system. At present, the project has achieved five major functions: load monitoring, efficiency monitoring, coordination monitoring, decision analysis, and simulation prediction.
According to Shen Xiaoqiu, director of the Transportation Supervision Center of Xiamen Power Supply Company, the company's “Online Monitoring and Analysis of Distribution Network Operational Efficiency†system took the lead in realizing the calculation of the full amount of equipment in the State Grid Corporation, integrating GPMS3.0, GPMS2.0, EMS, and The detailed data details of multi-service systems such as electric information collection realize the penetration between 10 kV public transformer, 10 kV feeder, 35 kV main transformer and line, 110 kV main transformer and line data. Through this system, the distribution network operation data analysis can be realized, and the input and output efficiency of the regional distribution network can be objectively and fairly evaluated, thereby creating considerable economic and social benefits.
“In terms of management efficiency, the project will promote comprehensive coordination and deep integration of operational monitoring and analysis work with the main business, and provide auxiliary decision support and management technical means for distribution network management; in terms of economic benefits, the project will pass weak links. Analysis and optimization measures effectively improve the operational efficiency of the distribution network, significantly reduce or delay investment, significantly improve the efficiency of input and output of the distribution network, achieve sustainable development of the distribution network, enhance the overall efficiency of the company, and reflect the social value of diversification and The company's social responsibility." Shen Xiaoqiu said.
In the next step, on the basis of the pilot operation of the Xiamen Power Supply Company, the Fujian Electric Power Company will also deepen the application and function of the “On-line Monitoring of Distribution Network Operation Efficiency†system, and further improve the system operation analysis, promotion and application and big data.
