Voltage and Frequency Control of SEIG in Small Wind Power Plant Using VFC

Abstract

This paper deals with the application of an 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. Voltage Sourced Converter (VSC) along with Battery Energy Storage System (BESS) is used to handle power flow between the SEIG and loads. The proposed control scheme, using a single voltage closed-loop control, is found to be suitable to regulate both voltage and frequency. A strategy for controlling the voltage and frequency of a wind generation system is presented in this paper. A mathematical model of wind generation system and synchronous generator has been developed and MATLAB model of the integrated system is developed for simulation studies under varying load conditions. It is found that a wind generation system along with a synchronous generator and STATCOM is able to maintain the voltage and frequency of the system constant. The synchronous generator helps in reducing the reactive power supplied by STATCOM and hence a reduced capacity STATCOM could be used for the purpose
