Abstract

When induction motor moves, power quality decline of line is risen seriously because provoking voltage drop the moment to system power supply by excessive moving current as well as power-factor drop in case drive by light-load because current reaches in 6 times $\sim$ 8 times of rated current. In this paper, a modeling did an distribution system 13 bus type model and induction machine load presents in IEEE using a PSCAD/EMTDE package, and it displayed an accident conspiracy and a compensating factor of DSTATCOM through simulation show.

유도전동기는 기동 시 전류가 정격전류의 6$\sim$8배에 이르기 때문에 경 부하로 운전하는 경우에는 역률을 떨어뜨릴 뿐만 아니라 과다한 기동전류로 인해 계통전원에 순간전압 강하를 유발시켜 선로의 전력품질저하가 심각하게 대두되고 있다. 본 논문에서는 PSCAD/EMTDC 패키지를 이용하여 IEEE에서 제시한 배전 계통 13버스 모형 모델 및 유도기 부하를 모델링 하여 사고모의 및 DSTATCOM의 보상효과를 시뮬레이션을 통하여 보였다.
