Development and application of the real-time stability control system in small scale power grid

The advantages and disadvantages of three realization ways of stability control strategies are analyzed. The development and application demand about the online real-time stability control system in small scale grid is proposed. Firstly, the implementation including hardware structure, software structure and main technical specification of the online real-time stability control system based on ultra real-time simulation is introduced. Then the main technical problems involved in the system are elaborated, including the ultra real-time simulation algorithm, stability control decision, high speed real-time communication program and coordinate scheme with multi-decision ways. The engineering practicability is verified by the application of the online real-time stability control system in independent local power grid and enterprise owned power grid. Finally, the research direction of popularizing the online real-time stability control system in large power grid is expected.
