Research Of The Power Distribution Equipment Maintenance Models Based On Condition Monitoring

In this thesis,the background and significance of the implementation of Condition Based Maintenance about equipments of power distribution network were introduced. This article described the basic theoretical knowledge associated with models of Condition Based Maintenance, analyzed the present situation of primary equipments'maintenance as well as the necessity and feasibility of CBM to carry out in distribution network equipments. The acquisition of state information and the process of CBM model were described in detail. This paper concentrated on the application of PHM in the decision-making process of CBM of distribution network equipments. A program in MATLAB simulation platform was written to achieve the parameter estimation of PHM. Took the transformer for an example, a set of monitoring data about transformer oil dissolved gas was selected to illustrate the application process of PHM model in the decision-making process of transformers condition based maintenance .
