해상풍력 발전단지의 전력망 연계방식에 따라 설치비용이나 고장전류의 크기가 달라진다. 그렇기 때문에 단지의 용량과위치 등을 고려한 효율적인 전력망 연계 방법이 필요하다. 특히 해상풍력 발전단지의 전력케이블은 대부분 비용 및 효율적인부분을 고려하여 3-core를 사용한다. 케이블 단락 같은 고장이 발생하면 케이블 전체를 교체해야 하므로 수리비용 및 터빈정지 기간을 고려하였을 때 비용적인 측면에서 상당한 손실이 발생할 수 있다. 따라서 본 논문에서는 제주해상에 설치될 100MW 풍력단지에 방사형, 링형, 성형 방식을 도입하여 이에 따른 3상 단락고장을 PSCAD/EMTDC 프로그램을 활용하여 컴퓨터 해석을 수행하고, 그 결과를 분석하여 모델 단지에 알맞은 전력망 연계방식을 제안하고자 한다.
Abstract
The installation cost or the magnitude of the fault current varies depending on the grid connection method of theoffshore wind farm. Therefore, there is a need for an efficient power grid connection method considering the capacity andlocation of the complex. In particular, most power cables in offshore wind farms use 3-core considering cost andefficiency. In the event of a failure such as a short circuit, the entire cable must be replaced, which can lead tosignificant losses in terms of cost, considering repair costs and turbine downtime. Therefore, in this paper, a radial, ring,and molding method is introduced into a 100 MW wind farm to be installed at Jeju offshore, and a three-phase shortcircuit failure is performed using a PSCAD/EMTDC program to perform computer analysis. I would like to propose asuitable power grid connection method.
