Study on Induced Voltage and Current of 500kV Common Tower Double Transmission LineSwith Parallel Reactors

摘要

Induced voltage and induced current of 500kV Common-tower Double-transmission Line are analyzed in this paper. Theory analysis for induced voltage and induced current of parallel reactors has also been demonstrated. Jmarti model is often used in transmission line models. It is a frequency dependent model with constant transformation matrix. Induced voltage and induced current is verified by electromagnetism transient simulation software EMTP. Reasonable selection of parallel reactors is suggested by calculation results. It has practical significance for designing and choosing Earthing Switch(ES).
