Risk quantitative assessment method, device and equipment for cascading failure of power grid

The invention relates to a power grid cascading failure risk quantitative assessment method, device and equipment, and belongs to the technical field of power system risk assessment. The device comprises a grid structure, a target power grid power supply structure and target power grid overall power flow distribution information; based on a preset model and the risk factor data, determining the occurrence probability of each risk factor and the level of consequences generated after the cascading failure occurs; according to the occurrence probability of each risk factor and the grade of consequences generated after the cascading failure occurs, the risk of the cascading failure of the target power grid is quantitatively assessed, so that the risk of the cascading failure of the power grid is assessed, early warning is performed, loss is reduced, and the problem urgently needs to be solved in the prior art. 本发明涉及一种电网连锁故障的风险定量评估方法、装置及设备，属于电力系统风险评估技术领域，该方法、装置及设备通过获取目标电网连锁故障的风险因素数据，风险因素数据，包括：网架结构、目标电网电源结构、目标电网整体潮
