Analysis on Power Load and Consumption Characteristics of Representative Consumers

Based on the investigation of more than one hundred representative consumers in Shanghai,Tianjin and Beijing,this paper compares the load characteristics of several kinds of power consumers and summarizes their basic characteristics from aspects of load density,annual maximum load utilization hours and load characteristic curves.Several solutions are proposed in order to improve the accuracy of distribution network planning for "Twelfth-Five Plan"(2011-2015),including enhancing the collection and management of the power consuming information of power consumers and conducting study on optimal combination of representative consumers.
