The Calculation of 750kV Line Parameters Based on ATP-EMTP Simulation
2016 International Symposium on Computer, Consumer and Control (IS3C)(2016)
Abstract
Transmission line is one of the major components of the power system. It is great significance to accurately obtain the frequency power parameters of transmission line for the entire power system to operate safely and reliably. In order to acquire the power frequency parameters of 750kV overhead line, a new method is proposed in this paper. This method gets the transmission line parameters by artificially eliminating the ground wires. Namely through steady calculation, the head end of voltage and current parameters of the lines are obtained, next transmission line parameters equal the voltage value divided by the current value. In this paper, the author does a simulation to calculate the 750kV transmission line parameters by ATP-EMTP, and out of this comes the transmission line parameters derivation formula, which is also verified by using ATP-EMTP model, and ensures the correctness of the calculation.
