S Company Case Study Based On RCM Substation Equipment State Overhaul Management

With the progress of electric power technology and the development of power grid scale,power grid is more and more important to our society.In this background,how to comprehensively improve the maintenance strategy for power transformation devices,as well as how to comprehensively promote the condition based maintenance for power transformation devices become an important issue.This paper,based on the topic background and meaning as well as the overview research of condition based maintenance domestic and overseas,elaborated on the theory and technology of equipment maintenance,condition based maintenance and RCM maintenance.This paper set S company's power transformation device as example,analyzed related condition,feasibility and key measures in S company's condition based maintenance for power transformation equipment.According to the status,the paper put forward the strategy,made clear the overall target,organization,assignment,basic demand,procedure and management process,put forward the main method,condition evaluation and the major ways of decision.Also,this paper tried to apply the decision making system of RCM maintenance for power transformation equipment,and elaborated the system requirement,general structure and functions.The system confirmed the means and rules of the weight coefficient in device evaluation,built mathematic model,synthetically judged the priority of repairing based on the condition and reliability of devices,finally built a reliability-oriented evaluating mechanism for power transformation devices,as well as predicted the future improvement and development of condition based maintenance for power transformation devices in S company..This paper applied RCM theory and technology to the area of power transformation equipment maintenance,developed the RCM maintenance management system,built a set of assessment mechanism oriented by reliability,offered a method of priority judgment when fixing equipment based on the health and reliability of equipment,gave mathematical support to the operational analysis of power transformation equipment.Meanwhile,this paper can be a reference to electric power company's condition based maintenance based on the RCM.
