Research on new type of asymmetric load compensator control strategy

This paper proposes a SVC compensation algorithm based on the new control methods aiming at the growing diversity of asymmetric load conditions, through applying the theory of instantaneous reactive power to static reactive power compensation equipment(Static Var Compensator)control that is used to increase power factor and compensate unbalanced three-phase. Based on symmetrical component method,through the load current decoupling into active component and reactive component,and by the use of the isolated reactive current to calculate the ideal compensation susceptance,the proposed algorithm simplifies the traditional asymmetric compensation algorithm.At last, the proposed control algorithm is simulated and modelled using Matlab/simulink, and the control for SVC is established. The correctness and feasibility of the proposed scheme are verified by simulating results.
