| Abstract: | The ice-melting device based on power electronics possesses functions of ice-melting by DC current and static var compensation, so there is a broad application prospect of this device. Taking the DC ice-melting project applied in Fuxing substation for example, its structure and features are analyzed, and a protection scheme for this DC ice-melting device, including AC over-current protection, AC under-voltage protection, short-circuit protection for valves, over-current protection for DC circuit, under-volt... |
