Abstract

This paper presents suitable designs of Proportional-Integral (PI) controllers for Rotor Side Converter (RSC) and Grid Side Converter (GSC) of wind turbine generator type Doubly Fed Induction Generator (DFIG) in order to control the current, voltage, and the power in RSC side and the power in GSC side of Wind Energy Conversion System (WECS). Besides, the proposed controllers have been designed to reduce the overshoot fault current when different types of disturbances occurred. The optimal parameters design of the proposed PI controllers is presented too by using intelligent technique namely; Bee Colony Optimization (BCO). The first stage of this paper includes the constriction of PI controller based on trial and error method in order to study the full performance of the WECS system. The second stage contains the construction of an intelligent controller; PI based BCO in order to get the optimal parameter design that meets all the requirements. In each stage, the wind speed has taken to be fixed and variable. Three types of faults have been implemented at the terminal of wind generator namely; Single Line to Ground fault (SLG), Double Line to Ground fault (DLG), and Three Line to Ground fault (TLG). The proposed approach has been implemented on a wind energy system connected to a network similar to Iraqi national network in voltage magnitude and frequency. Finally, the study shows that the use of PI controller based BCO is a suitable choice for reducing the overshoot fault current and in enhancing the full performance of WECS.
