Research and Application of Fire Risk Assessment Based on Satellite Remote Sensing for Transmission Line

Forest fire risk estimation is essential for China national grid company for their routine transmission line maintenance. The risk assessment model needs both remote sensing and meteorology data as input. This paper showed a wildfire risk assessment system which has been successfully applied in Hubei province covered all the 500kV transmission power lines and towers. This system has realized the classification of risk for different areas in transmission line. The results have shown that, combined with data fusing methods, such as, internet technology, remote sensing technology, expert system and data mining, areas along transmission line with high wildfire risk can be effectively obtained by the proposed system. This system could be used as a guide for forest fire and wildfire estimation which will be useful for the Hubei grid company to arrange their routine maintenance.
