Power device safety operation evaluation method

The invention belongs to the technical field of power system power devices, and particularly relates to a power device safety operation evaluation method. According to the evaluation method, a relation model between evaluation parameters is firstly built, on the basis, weighting and other mathematical adjustment are carried out on each parameter, results after adjustment are subjected to crossing and integration, and the data after crossing and integration are adjusted again. The power device safety operation evaluation method has advantages of accurate evaluation by an information redundancy technology method and also advantages of convenient operation by a scoring method; on the basis of not changing the algorithm, evaluation parameters are increased and decreased, and degradation and extension are easy; and in addition, when the method is adopted to evaluate the power device operation state, all evaluation indexes do not need to be traversed, the G matrix of the invention only needs to be monitored, and th
