Wind Turbine: Mechanical output power of the turbine (W).

By Sidhartha P and N. P. Padhy

Abstract

Abstract—In recent years generation of electricity using wind power has received considerable attention worldwide. Induction machines are mostly used as generators in wind power based generations. Since induction machines have a stability problem as they draw very large reactive currents during fault condition, reactive power compensation can be provided to improve stability. This paper deals with stability improvement of a distribution system embedded with wind farms by using power electronics based Flexible AC Transmission Systems (FACTS) reactive power compensator controller. The dynamic behavior of the example distribution system, during an external three-phase fault and under various types of wind speed changes, is investigated. The study is carried out by three-phase, non-linear, dynamic simulation of distribution system component models. Simulation results are presented for different cases such as with and without FACTS and also for different modes of operation of FACTS controller. The effect of constant wind speed and linear change in wind speed on stability is also analyzed. The simulation analysis of stability of distributed system with wind farm is performed using MATLAB/SIMULINK. Keywords—Distributed generation, distribution system, FACTS, reactive power compensation, power system stability, wind turbine induction generator
