Firing Angle Control of Soft Starter for Reduction of Inrush Current during Induction Generator to Gird

유도발전기 계통 연계시 돌입전류 저감을 위한 소프트 스타터 점호각 제어

Simulation model of induction type fixed speed wind power generator is developed. It is shown that the peak value of inrush current during start up changes according to the firing angle control strategy of soft starter. New proposed firing angle control scheme showed $25\%$ of reduction of peak current which results in smaller drop of gird voltage at the point of common coupling during start up.
