Article Preview

Considering that conventional AC de-icing method has many shortcomings such as complicated braking operation and difficult arrangement for power operation modes, we propose the new AC de-icing technology using capacitor compensation. On this basis, a novel regulative capacitor series-wound compensating AC de-icing equipment is developed, which works through controlling the line current to be within the permitted range in order to melt the ice. By the unique design mechanism of changing the series-parallel connection modes of capacitor combination and capacitor number for each combination, this equipment can make reasonable compensation for transmission line of arbitrary length within 40 km. Field test at JiLi 220kV substation of Hunan province manifests that this new-style AC de-icing equipment has remarkable effect with low energy consumption, simple operation and low engineering cost, thus has bright prospects of engineering application.
