Operation risk assessment method and system based on power grid failure rate

The invention discloses an operation risk assessment method and system based on a power grid fault rate. The method specifically comprises the steps of collecting fault data information, detecting the fault information, carrying out data processing on the collected data and the fault information, and storing a processing result. According to the operation risk assessment method based on the power grid failure rate, the power grid system is intensified in a targeted mode, the abnormal condition resistance of the power grid is improved conveniently, and the power grid failure rate is reduced; the invention further provides an operation risk assessment system for the power grid faults, the fault rate of the faults at all the positions can be conveniently calculated through the fault rate calculation module, targeted maintenance can be conducted on the positions with the high fault rates according to data calculated by the fault rate calculation module, and therefore the fault rates of the positions where the fau
