| description | Analyzing the impact of equipment maintenance on the failure rate of relay protection equipment is helpful to the formulation of relay protection equipment maintenance plans and the realization of long-term stable and reliable operation of the power grid. Using the Matlab toolbox to fit the failure rate function of the segmented data based on the failure data of the relay protection device in a certain area. Then the genetic algorithm is used to fit the failure rate adjustment factor, a failure rate adjustment factor model based on data fitting is established. Finally, the model in paper and the model based on the Delphi method were evaluated based on equipment failure data in multiple regions. Research indicates: The failure rate adjustment factor model based on the Delphi method underestimates the ability of maintenance to reduce the failure rate of equipment. The model in the paper has a smaller cumulative residual error than the model based on the Delphi method. It can more accurately reflect the impact of maintenance on the failure rate of relay protection equipment. |
