Strategy control converter to enhance the performance in the grid-connected PMSG wind power generation system

Currently, there are several power converter topologies applied to wind power generation. The converters allow the use of wind turbines operating at variable speed, enabling better use of wind forces. The high performance of the converters is being increasingly demanded, mainly because of the increase in the power generation capacity by wind turbines, which gave rise to various converter topologies, such as parallel or multilevel converters. The use of converters allow effective control of the power injected into the grid, either partially, for the case using partial converter, or total control for the case of using full converter. In this work, is proposed an implementation of a wind cogeneration system using a permanent magnet synchronous generator (PMSG) associated with a power converter, in order to inject active power and improve harmonics compensation in the electrical power grid, in according to standard IEEE and IEC. The control strategy of the active power delivered to the grid by cogeneration is based on the philosophy of indirect control.
