基于前馈解耦的多电平静止无功发生器控制
Control for Static Multilevel Reactive Power Generator Based on Feedforward Decoupling
摘要
Abstract
The disadvantages of traditional reactive power compensation devices have large loss and low output voltage,which is difficult to meet the requirements of the power grid voltage level and capacity of modern power system,a cascade H bridge multilevel static var generator is designed by establishing the mathematical model of the system. In view of the system with strong coupling,the PI control based on feedforward decoupling is used in the inner loop,the PI controller is used in the outer loop. The simulation results show that the proposed control strategy has fast dynamic response,high stable precision and good compensation effect.关键词
