State Evaluation Technology of Secondary Equipment in Distribution Automation System
Distribution network secondary device is an important guarantee for the safe and stable operation of distribution network.This paper intends to establish a failure probability estimation method for distribution network secondary device based on state score by identifying and constantly paying attention to the risk of distribution network secondary device,so as to achieve a quantitative description of the overall risk loss and risk size of secondary device.On this basis,combined with the actual operation of the power system,a maintenance plan for the auxiliary system of the power system based on the operation status of the power system is proposed,and the operation status of the power system is evaluated.
