Development of Dynamic Voltage Recovery Device with Uninterrupted Operation

As being plenty of nonlinear and impact toad, asymmetrical distribution network voltage caused by power network faults, as well as the flicker, fluctuation, harmonic, a tot of electric energy quality sensitive equipments can not be in the normal operation, which causes huge pecuniary toss. This paper introduces the working principle, operation pattern and hardware circuit of UDVR based on modern power electronic technology. The simulation and experiment of UDVR device show that it can be effective to restrain the influences of various voltage disturbance in power network on toad, and is the one of effective means of solving the quality problem of electric energy, to satisfy the power toad demand on quality of power supply. Along with the reduction of hardware cost, UDVR has extensive application prospect in power network.
