An Optimal Repetitive Control Strategy of Compensation Current for Distribution Static Synchronous Compensator
摘要
Abstract
The combination of proportional-integral (PI) and repetitive control strategy for the distribution static synchronous compensator (DSTATCOM) is able to improve the compensation accuracy of reactive power and harmonic and suppress the low-order harmonic in the output current generated by itself due to dead time,grid harmonic,etc.In order to eliminate the effect of fundamental delay caused by the controller and improve the dynamic performance and stability,the optimal repetitive control based on error adj ustment and the advanced internal model is designed.The input signal of the repetitive controller is dynamically regulated by hysteresis and attenuator according to the error amplitude of the reactive axis.It can reduce the influence of the repetitive controller on the feed-forward path and improve the response speed.According to the harmonic characteristics of the three-phase grid in the synchronous rotating coordinate,the advanced internal model is introduced to reduce the cycle delay to improve the response speed and stability.Simulation and experimental results have verified the feasibility and practicality of the method.关键词
