A Grid-connected Control Strategy of NPC Three-level Inverter For Direct-driven Type Wind Power Generator

摘要

Based on the mathematical model of the wind power grid-connected inverter, the proposed space vector PWM current control and double current control realize the decoupling for the current active component and reactive component. The simulation results show that the system can output three phase sine current which meet the requirement of the gird-connected, and the harmonic component is low.
