Research on Decision Support System of Relay Protection Equipment Status Evaluation Based on Mechanical Overhaul

Article Preview

Abstract:

Periodic mechanical overhaul is the most common model for relay protection equipments in power systems of the country. Over-treatment for minor illness or unnecessary treatment for disease-free of relay protection device that didnt need an overhaul would be arose by this model, which caused resource wastes and reduced the availability factor. The paper aims at evaluating and classifying the relay protection equipments, building centesimal evaluation model and prescient mechanical checkout model, as well as improving reliability of electricity grids by building condition-based maintenance, evaluation, decision and support systems of relay protection equipments.
