| Abstract: | Taking multi circuit 220kV/500kV transmission lines on same tower in Henan power system for example in which two 500 kV transmission lines are from Zhengzhou to East Zhengzhou and two 220 kV transmission lines are from Zhongmu to East Zhengzhou, a model of multi circuit transmission lines on same tower is built, and by which the induced currents and voltages among multi circuit transmission lines on same tower are researched and simulated. Through calculation and simulation, the general rule of induced currents and voltages among transmission lines that belong to different voltage classes and are arranged on same tower is obtained, and the requirements to parameters of grounding switches for 500 kV transmission lines from Zhengzhou to East Zhengzhou and that for 220 kV transmission lines from Zhongmu to East Zhengzhou to East Zhengzhou configured on the same tower are put forward. |
