Modeling and simulation of the fixed speed wind power generation system for grid studies

The paper aims modeling and simulating a wind turbine and its induction generator (WTIG) system as an electricity source in the power networks. System simulation has been done using the facilities offered by MATLAB/SIMULINK software. At first, equivalent models of various parts of a wind turbine generation system (WTGS) with fixed speed wind turbine (FSWT) are presented, and then an equivalent model of a wind turbine that operates in a grid connected mode is achieved by integrating these sub-models. The proposed equivalent models provide high accuracy for representing the dynamic response of wind power generation systems (WPGS) and can be used for power system simulations. Likewise, the analysis of the reactive power management of a WTGS consisting of FSWTs is carried out by using a static synchronous compensator (STATCOM). Regarding this matter, the rating calculation of the compensator for a FSWT is performed, and the effect of the network strength on the compensator rating is studied. Furthermore, the compatibility of FSWT with the mathematical models is evaluated by using simulation in MATLAB/SIMULINK environment.
