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