Performance Analysis of Wind Power Generator through Statcom

In Present Scenario wind power experiences a tremendous development of its installed capacities. Though, the intermittent of wind generation causes difficulties in the management of power systems. Reactive power management is an important issue in Power system. For this problem, the solution is FACTS device. Wind driven induction generator scheme is used. This paper deals with the application of a Self-Excited Induction Generator SEIG in a small wind power conversion system (WPCS). Such conversion system has capability to supply power demand of the loads with constant voltage and frequency, for which a power managing method is proposed. Induction generator connected with a capacitor bank to supply the necessary reactive power supply. The size of the capacitor bank is just enough to provide the support. Under the transient conditions such as faults or loading, the capacitor bank is not sufficient to supply the reactive power to the system. STATCOM will act under contingency conditions for the selected power system. STATCOM is used to handle power flow between the SEIG and loads Strategy for controlling the voltage and frequency of a wind generation system is presented. A mathematical model of wind generation system and asynchronous generator has been developed and MATLAB model of the integrated system is developed for simulation studies under normal and various speed conditions. Under contingency as describe earlier i.e. in fault, and the loading condition, the reactive power demand has to be met up.
