山火灾害对电网故障率的时空影响
Space-time Impact of Forest Fire on Power Grid Fault Probability
摘要
Abstract
According to the ways and mechanisms of electrical equipment faults caused by forest fire,a modified model of transmission line fault probability is developed.And an early-warning defense method based on the spatial-temporal distribution of power grid fault probability is proposed.Firstly,by combining forest fire information,geographic environments and meteorological information,the method is able to predict the forest fire behaviors and dynamically assess the transmission line flashover probability.Then,the spatial-temporal distribution fault probability can be obtained so that the higher the risk of potential faults is,the greater concern they will receive,thus raising the early-warning ability of power grids to prevent the forest fire.关键词
