Power distribution network risk assessment method in typhoon disasters based on space-time grid association

The invention relates to a power distribution network risk assessment method in typhoon disasters based on space-time grid association, and belongs to the technical field of power distribution networks. The method comprises the following steps: firstly, carrying out space-time grid division processing on an area where the power distribution network is located; Integrating multi-source informationof the power distribution network under the typhoon disaster, including power distribution network tower equipment information, typhoon meteorological information, topographic information and underlying surface information; Secondly, performing space-time association processing according to the divided grids and the disaster information of the power distribution network; Furthermore, risk grids are screened out according to the wind speed information, and a power distribution network disaster evaluation index system is established. 本发明涉及一种台风灾害下基于时空网格关联的配电网风险评估方法，属于配电网技术领域。本发明采用以下步骤，首先，对配电网所在区域进行时空网格划分处理；然后，整合台风灾害下配电网的
