Power distribution system reliability evaluation based on blind number
Haiwei Wang · Power System Protection and Control · 2011
Traditional power distribution system reliability evaluation takes the reliable parameter as point value to carry on the evaluation. But limited by the objective conditions,the reliable parameter has uncertainty,which will cause the inaccurate reliability evaluation. Through analyzing the various uncertainty factors in distribution network reliability evaluation,the methods to reasonably describe and process uncertainty information are researched. On the basis of the existing method in processing uncertainty question,this paper introduces blind number theory into distribution network power supply reliability evaluation,uses it to describe and process uncertainty information in distribution network reliability evaluation,and improves the accuracy of distribution system reliability evaluation. Through the example, the validity of the method is confirmed.
