Research on Induced Voltage of Insulated Ground Wire
During the operation of transmission lines,the insulated ground wire will generate power frequency induced voltage,which has a significant impact on operation and maintenance,as well as the insulation gap of the ground wire.Therefore,establish a simulation calculation model for the induced voltage of the ground wire of a 500 kV single circuit overhead line,calculate the induced voltage under three conditions:Full insulation of the ground wire,full insulation of the ground wire(single point grounding),and insulation of the ground wire(with effective grounding points along the line),analyze the influence of line length,transmission capacity,grounding point,etc.on the induced voltage,and propose effective measures to reduce the induced voltage.
