Calculation and Analysis of the Coupling Effects of High Voltage Transmission Lines in Joint-use Corridors Shared by Multi-systems
Electromagnetic coupling effects among transmission lines threaten the stability and reliability of each system,which the corridor is shared by.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.The model consists of 500 kV double-circuit AC transmission lines and 1000 kV one-circuit AC transmission lines.And then,the effects of various parameters on the generated interferences are analyzed,when 1000 kV AC transmission lines are de-energized.The general rules of induction components among transmission lines changing with different parameters are obtained.This paper provides an insight on how to make the safe distance of transmission lines in the corridors.
