Abstract

This paper presents a method for early fire detection and fire position determination inside the nacelle of wind turbine generator system. The rising temperature and obscuration rates inside the nacelle were used as parameters for fire detection, which can minimize the possibility of a fire detection malfunction because these rising rates do not depend on the absolute values of temperature and obscuration. The fire position was determined using the time difference among various sensor positions for fire detection. The performance of the method was tasted using sets of experiments in a nacelle simulator.

본 논문에서는 풍력발전기 나셀 내부의 화재 조기감지 및 화재발생위치를 판단하는 방법을 제안한다. 화재감지 변수로는 온도와 공기 혼탁도 상승률을 이용하는데, 이것은 온도와 혼탁도의 절대 값과 상관이 없이 화재를 감지할 수 있기 때문에 비화재보를 최소화 할 수 있는 방법이다. 화재발생위치는 다수의 화재감지 센서들의 거리에 따른 화재감지 시간차를 이용하였다. 또한 다양한 실험을 통하여 개발된 방법의 성능을 테스트하였다.
