The Power-Frequency Parameter Measurement Method Of Single-Circuit Transmission Lines Based On Transmission Line Equation

Firstly, a power-frequency parameter measurement method of single-circuit transmission lines based on transmission line equations is proposed; then a model is built by using MATLAB, and simulation comparison with the Newton - Raphson method is carried out, and the transmission lines' resistance, inductance and capacitance per unit length are obtained; then different measurement error is superposed upon the input of two different methods, and the stability of the calculated values is analyzed. The results show that the power-frequency parameter measurement method of single-circuit transmission lines based on transmission line equation is better.
