The power grid automation system detection and evaluation technology of the Electric Power Technology Institute is internationally leading

On September 10, after the appraisal of scientific and technological achievements, the research and application results of key technology research and application projects of power grid automation system detection and evaluation undertaken by China Electric Power Research Institute reached the international advanced level
.
、

The research and application project of key technologies for grid automation system detection and evaluation constructs the overall architecture of grid dispatching automation system detection and evaluation based on typical test cases.
A closed-loop disturbance simulation method is proposed to correlate the local disturbance data with the full-section data of the power grid, and realize the customizable simulation of the grid disturbance environment with multiple time scales, multiple voltage levels and different accident scales.
The construction method of standard interoperability test framework based on labeling technology is proposed, and a special standard interoperability test platform and online monitoring and evaluation system of main station operation status indicators are constructed.
The detection method of integrated monitoring system of substation was proposed and the detection platform was constructed.
An integrated intelligent component detection environment is built to realize the simulation test
of intelligent component operation.

It is understood that the overall detection and evaluation method of the scheduling automation system of the project and the simulation method of multi-source closed-loop disturbance environment have reached the international leading level
.
The project realized the detection and evaluation of the power grid automation system for the first time at home and abroad, which greatly improved the stability, standardization and reliability
of the power grid automation system.

At present, the research results of the project have been fully applied in the State Grid Corporation's grid dispatching automation system, substation integrated monitoring system, and conventional and grid access detection of intelligent components.
In addition, the online detection of scheduling system has been applied in many provincial control centers such as Jiangsu, Gansu, Henan, and Ningxia, and the centralized evaluation of system operation status has been realized for the first time, and the reliability
of system operation has been improved.

The results obtained in the research and application project of key technologies of grid automation system detection and evaluation ensure China's international leading position in similar technologies, fill the gap of well-known foreign testing institutions such as the Netherlands and Germany, and also make up for the shortcomings of domestic and foreign power grid automation system equipment products, and play an important role
in ensuring the safe and reliable operation of power grid automation system.
