Abstract
Taking Shandong Power Grid’s Yantai 500 kV switch station-Zhongxing Penglai Power Plant’s multi-circuit transmission line on the same tower as an example, a multi-circuit transmission line model on the same tower was established to study the induced voltage and induced current between the multi-circuit transmission lines. Under the above conditions, a digital simulation of the power system is carried out. Through calculation and analysis, the factors that affect the magnitude of the induced voltage and induced current between the circuits when the multi-circuit transmission line is erected on the same tower are obtained. Based on these influencing factors, the use of machine learning algorithms to quickly and accurately predict the magnitude of the induced voltage and the induced current is of great significance for judging the insulation requirements of switchgear for switching induced currents and the selection of grounding switches.
