PWM AC/DC boost converter system for induction generator in variable-speed wind turbines

This paper describes an induction generator system utilizing PWM AC/DC voltage boost control technology for variable speed wind turbine applications. The system consists of an induction machine as a generator and a PWM AC/DC converter (rectifier), followed by an inverter connected to a utility grid. The machine leakage inductance is employed as the boost converter inductance to store the magnetic energy and to transfer it to the electric energy of the DC link for the wind turbine inverter. To accomplish satisfactory performance of the wind turbine PWM AC/DC converter, we have employed the field oriented control (FOC) and deadbeat control methods to control the induction generator. From the simulation studies conducted on a variable speed wind turbine generation system, the proposed system can meet the requirement of the wind turbine for constant DC link voltage under variable wind speeds. The DC link voltage remains constant, so the high quality AC current can be sent to grid
