Simulation Results

The design of a Dynamic Voltage Restorer that is suitable for compensating regional voltage sags in 10kV distribution system is introduced in this paper. The design of the main circuit based on cascaded H-bridge, the device for energize DVR and the transformer-less coupled circuit are presented. For the voltage sags in neutral point non-grounded system, a reference voltage calculation method with the aim is to restore the line voltages on the load side is put forward. The simulation model of a substation including the designed DVR device has been built in PSCAD, and the compensation results under different fault types are simulated and analyzed, the influence of the energize device on the distribution system is studied. The simulation results verify the correctness and effectiveness of the design of DVR hardware and the reference voltage calculation method.
