Abstract

This paper proposes a method to prevent cascading trip based on the action of relay protection and the output of generator as the optimization variable for aiming at the cascading trip in power grid. Firstly, the critical state of cascading trip is discussed, and the safety index of cascading trip in power grid is analyzed based on the analysis of the performance of cascading trip and the action of relay protection. On the basis of this index, a kind of optimized model of cascading trip prevention is given while considering the various constraints of power grid synthetically. This paper presents a complete algorithm flow for solving the optimized model combined with particle swarm optimization algorithm aiming at the proposed optimized model. Finally, on a IEEE39 system, an example is analyzed by the MATLAB program, which verifies the rationality of the proposed method.
