A research of adaptive detection algorithm for D-STATCOM

This paper puts forward a new instruction current detection method, namely the model reference adaptive control algorithm for Distribution Static Compensator (D-STATCOM). The method is a kind of instructions from the adjustment of the online algorithm. Using MATLAB/Simulink tool for simulation of FBD method and adaptive method, results show that the dynamic response is fastest and the performance is best when using the adaptive control algorithm of DSTATCOM for compensation of reactive power and unbalanced loading. Simulation and experimental results demonstrate the effectiveness of model reference adaptive algorithm, and the stable operation of application, also proves that using adaptive detection algorithm of D-STATCOM device to dynamically compensate reactive power and unbalanced three-phase and restrain harmonics has good dynamics and practicability.
