Optimal control strategy of UPQC on variable phase angle control method

Abstract

The United Power Quality Conditioner(UPQC) is proposed one of the most promising solution for reducing PQ problems of load and source sides. Because of its outstanding performance.UPQCmade up of two types of power converters, it expansion of price.The optimal VA ratings in this paper the converter in the upqc are investigated compensating requirements due to system. Based on the phase angle control (PAC) method both active and reactive power supports series converter. PAC has the advantage of the displacement angleby adustingof corresponding changing online loading of VA. VariablePAC methodbacedon,the shunt and series of ratings converters to optimizea two-stage algorithm is utilized to obtain maximum power converters rates of utilization in the UPQC. Moreover, the proposed UPQC to minimize VA loadings of online for the dissimilarcompensating performances control alogorithms utilized. For proposed optimization algorithm the advantage with other approaches the proposed UPQC are compared. With the simulation proposed algorithms are validated.
