The Design of Circuits and the Research of Samples Based on the Phenomenon of Voltage Instantaneous Dither

Voltage instantaneous dither affects the stability of power system seriously, resulting in serious consequences and enormous economic losses. In this paper new circuits of super capacitors and AC sample circuits are designed. Via an algorithm the system can judge whether voltage instantaneous dither occurs quickly and accurately, microprocessor controls relays, releasing super capacitors energy to power the load via the inverter. The energy storage system designed making the super capacity fast charge and discharge, while energy storage system discharging, the super capacitors take advantage of its circuits recharging partially. The whole system can effectively resist incidents caused by voltage instantaneous dither phenomenon, ensuring factories to continue production and enable enterprises to avoid unnecessary losses.
