Abstract :
De-icing schemes and operations for overhead power line in 10kV, 66kV and 220kV networks based on shunt capacitor over-compensation method are proposed in this paper. This novel de-icing method is based on characteristics of sinusoidal AC and theory of shunt capacitor over-compensation. By utilizing 10kV capacitor bank, which is installed as standard apparatus in substation, reactive current can be transmitted to the specific de-icing power line, which leads to over-compensation of network, and temperature of the power line will be increased. This de-icing scheme and operations are proved and verified in 10kV network by on-site experiments. Focus on characteristics and structure of power grid in China, this method is feasible to transferred and applied in 35kV, 66kV and 220kV networks.
