Study on Double Closed-Loop Control Strategy of the Side Grid Inverter for Wind Power Generation System
For wind power system with external power grid connection, the grid inverter system to grid electricity must satisfy the requirement of the grid voltage and frequency. In analysis system based on the mathematical model of current transformer, this paper puts forward a network side inverter based on reactive voltage regulating voltage and current double closed-loop control strategy, through adjusting reactive power system bus voltage amplitude stability, also has realized the active reactive power decoupling control system, and low output current harmonic content, enables the system to the grid stable and constant frequency power. Through the simulation analysis, under the condition of load change system can realize stable control and has good current robustness, verify the feasibility of the control strategy effectively and accuracy, research on wind power grid technology has a certain practical value.
