A wind power generating system based on controlling power converter system and control method therefore

摘要

PURPOSE: Wind power generation system and control method thereof based on control are provided to reduce unit cost by controlling operation of a switch for system connection with a power converter system (PCS) within a system. CONSTITUTION: A wind power generation system includes a wind power generation module (100), a PCS module (300) and a control module (500). The wind power generation module includes an electrically excited synchronous generator (130) connected to the blades and exciter (150) applying current. The PCS module includes a machine side converter (MSC) (330) controlling power with a maximum power point tracking (MPPT) mode and a grid side converter (GSC) (350) supplying the power generated in the wind power generation module to the system power supply. The control module controls operation of the wind power generation module and PCS module and switches connection between the wind power generation module and system power supply.
