Optimization calculation method of transmission line loss with multi-parameter correction

Abstract

Line loss rate is an important technical and economic index for national assessment of power supply enterprises, and the accuracy of line loss calculation becomes more and more important. The current line loss calculation method does not consider the influence of load level, clock accuracy and metering device, resulting in a large difference between the actual result and the calculated result, which is not conducive to the lean development of line loss management. In this paper, the influence of temperature and humidity on theoretical line loss is considered, and a mathematical model for calculating synthetic line loss rate is established to eliminate the error caused by using single line loss, and the line loss rate is modified by multiple parameters. The case shows that this method is more accurate and closer to the actual line loss rate, which has strong engineering practice significance.
