摘要：
Recently, wildfires have become a key menace to the safe operation of electrical transmission systems (ETS). The existing fire monitoring methods are unable to obtain wide-area fire points and micro-scale meteorology data of the micro-topography area near the transmission lines in real-time, thus cannot accurately calculate the trip risk of transmission lines due to wildfires in real-time. A real-time analysis approach for transmission-line trip risk considering wildfire disaster was proposed. First of all, a dynamic threshold fire-point identify method for small size wildfires based on synchronous satellite was presented, and then a meso-micro scale weather forecast method of multi-nested mesh model was put forward to solve the conflicts between numerical accuracy and tide timeliness, also, a real-time transmission-line trip risk analysis approach which considers various environmental factors such as precipitation, vegetation and wind was proposed. Finally, the approach was applied to a high incidence period of wildfires in Hunan province as a case study, the analysis results show that the proposed approach can effectively analyze the trip risk of transmission-lines due to wildfires in real-time, and also provide supportive data to the safe operation of power grids under circumstance of large scale wildfires. © 2017 Chin.
