Abstract
A device for loop closing and breaking of a power distribution grid based on decoupled voltage regulation is provided. The device comprises a voltage-regulation phase shifter, a control system, a voltage acquisition device and a loop closing switch. The voltage acquisition device acquires voltage signals on two sides of the loop closing switch performing a loop closing or breaking operation and transmits the voltage signals to the control system. The control system calculates a compensating voltage amplitude and phase-angle according to the voltage signals, and sends an instruction to the voltage-regulation phase shifter according to the compensating voltage amplitude and phase-angle. The voltage-regulation phase shifter outputs the compensating voltage amplitude and phase-angle according to the instruction from the control system, to compensate for a voltage difference between the two sides of the loop closing switch.
