Abstract: A model predictive current control strategy is proposed for neutral point clamped（NPC） static var generator（SVG）.Since the prediction model of SVG is an open loop model,there is current tracking error between the actual output current and the instruction current on the AC side.Under the premise of balancing the calculation amount and the tracking accuracy,the evaluation function of current tracking accuracy error is designed,and the feedback correction of the predicted current is carried out to fulfill a closed-loop optimization.Taking advantage of the multi-step prediction of the prediction algorithm,the paper proposes a two-step prediction method to compensate the delay caused by sampling,calculation and control in the system,which improves the compensation performance of SVG.A simulation model is built in Matlab/Simulink for verification,and the simulation results show the effectiveness of the proposed strategy.
