Abstract

As a new Korean grid code which includes LVRT requirement to wind farm of which capacity is greater than 20MW is activated in 2012, this paper developed the analytical model of the Korean LVRT for the simulation based feasibility study of the wind farm interconnection into power systems. The developed model of the LVRT is verified by applying it into the performance evaluation of the wind farm interconnected power systems and the effect of Korean LVRT is analyzed through case studies considering typical disturbances of power systems.

본 논문은 국내에서 설비용량 20MW 이상의 신재생발전기에 대해 계통연계 유지조건을 의무화하는 송배전용 전기설비 이용규정이 2012년부터 적용됨에 따라 이를 모의해석 기반의 풍력발전기 계통연계 검토 시에 고려하기 위한 풍력발전기의 LVRT(Low Voltage Ride Through) 전사모형을 개발하고 이를 풍력발전기가 연계된 전력계통의 성능평가에 적용하여 전사모델의 유용성을 검증한 후 전력계통의 대표적인 상정고장에 적용하여 국내 풍력발전기 계통연계 유지조건의 적용효과를 분석하였다.
