A Case Study On Condition-Based Maintenance Management For Power Distribution Equipment In D Power Supply Corporation

This case paper is to describe D Power Supply Corporation of the present situation of condition-based maintenance management for power distribution equipment, the problem in management and how to improve the management level to solve the problem. And this paper is in order to explore scientific, reasonable, economic, and adapt to the situation of our country’s maintenance management system.Since the1950s, the power distribution equipment maintenance has been implement preventive maintenance system in our country. With the progress of science and technology and the development of economic, the capacity of the power grid increases gradually, also put forward the higher requirements of customers on the stability of power grid, the traditional system of preventive maintenance have been unable to meet the requirement of network security and operating economy, new maintenance system is put forward. Since the early1990s, the domestic research and exploration of condition-based maintenance has begun. After many years of practical experience summary, in recent years, the condition-based maintenance for power distribution equipment as an important means to reduce maintenance cost has been paid more attention to enhance the reliability of power supply and got a promotion in State Grid Corporation of China. Condition-based maintenance management, however, in the process of gradual popularization also exposed the lack of management on a certain extent, how to fully draw lessons from the successful experience of developed countries in the power grid equipment maintenance, relying on the progress of scientific and technological and the innovation of management, and how to summarize the method adapt to the actual equipment maintenance management will be an important topic.Based on the case study of condition-based maintenance management in D Power Supply Corporation, analysis of the developed countries total production maintenance and reliability centered maintenance strategy, points out the problems of the condition-based maintenance, and put forward new ideas to optimize maintenance management, including the type selection of equipment, comprehensive evaluation of equipment, the way to decision the type of equipment maintenance as well as the suggested corresponding safeguard measures, built an equipment maintenance management model based on TPM, RCM, LCC, risk assessment and other management concept, so that the arrangement of the equipment maintenance tasks becomes more scientific, reasonable and efficient, saving the maintenance of manpower, financial and material resources, to improve the reliability and stability of power system.
