Research on Intelligent Parameter Estimation Method of Distribution Equipment Fault Rate Model

In recent years, with the rapid development of China's economy and power grid construction, the scale of power system and urban power grid has been expanding. The distribution network has been continuously transformed and expanded, and its scale has also been expanding. Reliability is an important standard for evaluating distribution system. In this paper, the intelligent parameter estimation method of distribution equipment failure rate model is studied, the mixed distribution model of component failure is established, the parameter estimation method in the mixed distribution model is proposed, the historical data of a certain stage is selected, and the proposed model is verified by three comparison schemes, The validity of the model is ensured.
