| Abstract: | The paper introduces a dynamic AC voltage stabilizer that is used to solve the problem of power quality about vohage sags, voltage swells and harmonics in power system. The theory is to inject series voltage to eliminate the voltage disturbances by series inverters for realizing voltage stability on load. Using the statespace averaging method,this paper sets up the mathematic model of the voltage stabilizer and discusses its control strategies. In order to improve the equipment performance, a current feedback control strategy for the dynamic AC voltage stabilizer is proposed. Experimental results verify the validity and effectiveness of the equipment. |
