Electrical Shares Calculation of AC Transmission Line Based on Instantaneous Value
摘要
Abstract
ABSTRACT:The correct calculation of multi-electrical-user’s share coefficients on the AC transmission line is about the objective and fair solutions for many power system’s technical and economic issues. However, the problem has not yet reached a consensus on computation method. This paper reviewed and found that the research ideas of the existed methods were generally based on the mean values of AC circuit physical quantities and established calculation formula of electrical shares from the phasor analysis. These ideas might store up method’s theoretical defect from the start. This paper returned to probe into solution of problem from the AC circuit instantaneous value. Firstly, defined instantaneous electrical share (ES) coefficients of AC transmission line according to the actual direction and magnitude distributions of electrical-user’s and transmission line’s instantaneous powers or currents. Secondly, calculated the mean values of instantaneous ES coefficients for a specific period of time. The way of calculating the mean value after calculating the instantaneous value of a studied physical quantity conforms to the general assessment idea for relevant physical quantities with arbitrary continuous time processes. Based on the above analysis, this paper derived analytical formulas of instantaneous and mean ES coefficients of transmission line for different connected- mode users such as receiving-bus equivalent load users, sending-bus equivalent source users, sending-bus equivalent source and load users, and receiving-bus equivalent source and load users. Theoretical proof and numerical comparative analysis show that the calculation method of ES coefficients from instantaneous value analysis is of more theoretical correctness, and there can be as early as possible for obtaining the consensus results.关键词
