Research on Control Strategy of Three Level Static Var Compensator
In recent years,the grid connected power generation of new energy has been increasing.In this context,it is necessary to improve the stability and power quality of the power grid through technical measures.The three-level static reactive power compensator plays an important role in achieving the above goals.The traditional voltage and current dual closed-loop pulse input control strategy has certain shortcomings and cannot adapt to high-power scenarios.The research process focuses on analyzing the multi-step predictive control algorithm in the model predictive current control strategy and applying it to three-level static reactive power compensators.After simulation,this control strategy significantly reduces the total harmonic distortion and switching frequency of the power grid current,making it more practical.
