Abstract
In order to solve the problem of zero-sequence protection tripping of 35 kV four-circuit parallel overhead lines on the same tower in a photovoltaic power station in Guangxi,the simplified calculation formula of each sequence unbalance degree of four-circuit parallel overhead lines on the same tower is derived by using the approximate calculation method based on Casson's formula,and compared and verified them with the calculation results of wave recording data and PSCAD/EMTDC software simulation results.By analyzing the generation mechanism and influencing factors of unbalanced current,considering the weight of each imbalance degree,an optimization method of phase sequence arrangement based on analytic hierarchy process is proposed.The optimized phase sequence arrangement scheme calculated by this method is applied to the line,which greatly reduces the unbalanced current and successfully solves the problem of zero sequence protection tripping.关键词
