Abstract

To solve the problems such as the increasingly close structure of the 500kV/220kV electromagnetic loop network and the high level of short-circuit current in power system, it is of great significance to study a practical and economic comprehensive optimization method for limiting short-circuit current. In this article, a comprehensive optimization method of short-circuit current limiting measures is proposed considering the safety efficiency cost of current limiting measures. Firstly, a dimensionality reduction strategy considering the sensitivity of current limiting measures is proposed. And then a comprehensive optimal allocation model of current limiting measures considering system stability, current limiting effect and investment cost is established. Finally, the order optimization algorithm is used to solve the model. The accuracy and effectiveness of the proposed method are verified by an actual power grid in a province of China.
