Calculation and Analysis of the Coupling Effects of High Voltage Transmission Lines
Introduction :
Electromagnetic coupling effects among transmission lines threaten the stability and reliability of each system. This paper investigates the effects of various parameters on the electromagnetic interference among transmission lines in detail. The influencing factors include erection parameters,soil parameters and operation parameters of power system . A multi-conductor transmission line model is established to calculate the coupling effects of transmission lines with EMTP(a simulation software)
The model consists of 500kV double-circuit AC transmission lines and 1000kV one-circuit AC transmission lines. And then,the effects of various parameters on the generated interferences are analyzed, when 1000kV AC transmission lines are de-energized.
