10kW급 풍력발전용 계통연계형 인버터 시스템 구현

In this paper the implementation of a grid-interactive inverter system for 10kW wind power generator. This system consists of a three-phase rectifier and a three-phase inverter. The three-phase rectifier in the system connects to wind power generator. The output of the three-phase rectifier is connected in series to a DC-link capacitor and the input of the three-phase inverter. The output of three-phase inverter is connected in parallel to a grid. The main function of this system is to provide unity power factor, lower total harmonic distortion (THD) and active power support. A 10kW test model of the system has been built using IGBT controlled by a digital signal processor (DSP).
