Research on DC-Side Voltage Simple Fuzzy Control Method of DSTATCOM
The stability of DC-side capacitor voltage is the prerequisite that distribution static synchronous compensator (DSTATCOM) can work properly．To solve the problems of the traditional control method which include large amounts of overshoot and starting current during the establishment of DC-side voltage,a simple fuzzy controller is designed．The controller is from the angle of regulating DC-side voltage reference value,and achieves the effect of ladder type non-overshoot boost of DSTATCOM．The new method not only resolves the problems of the conventional PI controller which requests the higher precision of models,easily leads to overshoot and has poor ability to resist disturbance,but also reduces latency time brought by the general fuzzy control effectively．The proposed simple fuzzy control strategy is verify by MATLAB and a self-made 10KVA DSTATCOM experimental prototype,and results prove the effectiveness and feasibility of the new DC-side control strategy．
