Performance Investigation of Wind Turbine Induction Generators connected with a Single-Area Power System

Abstract

Wind turbine power is a vital source of renewable energy and accounts for major plants in generating electricity in various countries. The aim of this paper is to developthephysicalmodel of three types ofwind-turbineinduction generatorsand to investigate their impacts on the frequency in a single-area power system. The generator types are as follows: (i) squirrel cage induction generator (SCIG); (ii)doubly-fed induction generator (DFIG) and (iii) brushless doubly-fed induction generator (BDFIG). The analysis scenario isdemonstratingthe effect of variablewind speedson the grid frequency under load variations. The simulation results show that BDFIG achieves better performance in comparison with DFIG and SCIGin terms of maintaining the grid frequency.
