Description

technical field [0001] The invention relates to the technical field of a method for calculating power frequency parameters of high-voltage transmission lines, and belongs to the application of computer technology in the estimation of power frequency parameters of high-voltage transmission lines. Background technique [0002] The transmission line is an important part of the power system, and the power frequency parameter is the important characteristic data of the transmission line. It is necessary for the establishment of the mathematical model of the power system before the power flow calculation, relay protection setting calculation and selection of the power system operation mode. Parameters, the accuracy of power frequency parameters is related to the safe and stable operation of the power grid. There are two ways to obtain line parameters: one is obtained through actual measurement, and the other is obtained through theoretical calculation based on the line arrangement...
