Abstract


In recent years , the development of grid scale , the probability of the line across the forest area increases, more and more under the influence of factors such as global warming hill fire line trips caused power outages , a threat to the normal operation of the power company normal production and the national economy . Outbreaks of the large area of hill fires affect the number of transmission lines , will pose serious challenges to the safe and stable operation of power grid . In order to reduce and prevent the occurrence of such incidents in the paper from transmission lines hillfire forecast , monitor and change the run prevention hill fires studied the grid Prevention hillfire measures . This paper the use of extreme learning machine to predict the hill fires , training learning using statistical fire data and verified with the transmission lines hillfire 2009 data , the results showed that the extreme learning machine in the hillfire forecast there are good accuracy . Monitoring system the transmission lines hillfire transmission line disaster monitoring network and satellite infrared remote sensing system combined , the system will not only be able to monitor to a transmission line near the small range of hill fires , but also to predict and near-real-time grasp the development trend of the fire . Predicting and monitoring the results will the grid Prevention hill fire and start transmission lines hillfire accident plans to provide a reference . Topography, climate and customs of other factors combined Hunan analysis Hunan 2-4 months of hill fires multiple reasons , but also qualitative analysis of the reasons , and the vast majority of the hill fires caused by transmission line trip trip reclosing failed . formulated the grid the prevention hillfire measures to provide theoretical support . The paper also analyzes the transmission line load transfer affected by hill fires upcoming outage of the line , such as changing the operating mode of the program is applied to the transmission the line anti hillfire feasibility , and PSASP software WSCC nine - node system simulation analysis to prove this program is viable ; final analysis the the transmission lines hillfire contingency plans for its system , and systematic so the grid hillfire prevention measures . Hill fire prevention measures on the grid integrated , system analysis , power grid companies can quickly and orderly processing to provide a reference for the transmission line hillfire accident .
