Wide-area intelligent protection system based on genetic algorithm

Abstract

This article brings forward a wide-area intelligent protection system based on abundant power network information by analyzing the practical application of wide area protection and further combining it with the recent development of power network. The system works with main protection system and strengthens the capability of power system relay protection and simplifies the backup protection. This paper also gives the decision-making and working mode of a new intelligent protection including the principle of state correlation wide-area protection and the principle of fault identification based on genetic algorithm. A fault mathematical model based on genetic algorithm is developed. The results of the simulation test prove that the validity and good fault-tolerance capabilityof the model proposed.
