Abstract
In recent years, with commissioning of EHV transmission projects, main power system network has a successive increasing scale, causing a dramatic increase of transmission lines extend through forest region. Influenced by global warming and widespread drought, wildfire has a obviously rising trend in frequency, which brings about more tripping faults of transmission line. Even worse is that, the operation safety of main power system network can be greatly threatened under circumstance of forest fire breaking out near transmission lines corridor. For the reasons above, in this article, based on the operating data of 500kV transmission lines governed by an EHV transmission company in past 6 years, with consideration of evolution laws of wildfire, by statistical analysis of fault location distribution of line tripping induced by forest fires, the regional feature and spatial-temporal feature is studied, as well as the characteristic of low auto-reclosing success rate after wildfire-caused tripping faults. And on this basis, the suggestion on wildfire prevention in many respects is given, such as fire monitoring, vegetation clearing of line corridor, emergency management and so on.
