Evaluation of distribution network reliability based on network equivalent

Abstract

The reliability of distribution system of electricity is one of the most important indicators to measure the ability that the power supply system sends electric power to the load continually. Also it is an important technical and economic indicator for the power supply enterprise. In this paper, the theory about the reliability of distribution power system have been studied, a method of network equivalent is introduced. The validity of this method is examined by an example of distribution system of Pudong International Airport. Finally, the article analyses a number of factors which may influence the indicators of reliability. © 2011 Springer-Verlag Berlin Heidelberg.
