【正文】 t or subsystems leading to serve a particular load would receive uniform and consistent level of maintenance in all departments, thus enhancing and optimizing the maintenance process. In order to establish a maintenance program, the RCM process needs to be the driving point. Figure 2. Shows different strategies required for a maintenance optimization program. The classical RCM process involves identifying the systems to be studied, their functions, functional failures, failure modes, failure causes, and the maintenance task selection The most critical pieces of equipment which affect the overall function of the system need to be identified. In other words, we need to identify equipment with severe consequences when 一種實用的供配電系統(tǒng)的維護優(yōu)化計劃 12 failed. Also, critical customers and the equipment leading to their loads need to be identified. All equipment affecting these customers need to be analyzed, and the most critical pieces of equipment should be determined. We also need to understand the customer needs in terms of reliability, safety, power quality, cost, etc. These attributes must be weighted to determine the optimum maintenance policy to deal with these customers. In order to optimize the utilities’ maintenance program, all relevant information must be used to most effectively initiate, schedule, track, record, and analyze maintenance tasks. An open munication protocol that enables various monitoring devices (regardless of the manufacturer) to talk to each other, with utilityoffices, and with control centers would best suit the needs of electric utilities by integrating various data sources and other software modules. Currently, many large utility organizations perform some equipment diagnostic tests. Many have puterized their maintenance work management functions including retaining maintenance histories, logging significant operational activities, and maintaining a library of design information for equipment. The proper munication, integration and analysis of all of this information would result in more accurate remendations concerning when to perform maintenance and/or how to operate a specific piece of equipment. A typical problem in the industry is that, at times, a large amount of data is collected but it is not integrated and processed expediently for a quick evaluation. This results in the inability to make immediate Oamp。Mremendations, therebyadding cost for the collection of data while failing to provide cost benefit which could have been realized. Other factors that may contribute to maintenance improvement are: application of inexpensive sensor techniques and effective diagnostics to maintain equipment’s health。 data coordination from multiple sources for analysis and decision making。 a system for efficient exchange of information across Tamp。D and substations。 and experienced pool of trained professionals. The management should be prepared to invest in staff and hardware/software to actively manage the maintenance program. A team approach to RCM must be retained and the concept of RCM must be accepted in the organization. In order to use appropriate software and hardware, education and training efforts should be an integral part of this process. The understanding of the basics of utility’s maintenance program and the working knowledge of the tools required by the staff must be assured. The key to sustaining a successful maintenance program is the development of a process that will ensure the continuance of maintenance program over a long period of time. It is necessary to periodically review and update the maintenance program using a structured method. Today, cutting operations and maintenance costs and preserving service reliability are the top priorities for managers of utility transmission and distribution systems. The concept of RCM is sound and should provide utilities with a structured approach to a maintenance program with an optimum balance between cost of maintenance and reliability improvement. RCM and PdM analyses plement each other, and when performed simultaneously, offer an excellent approach to maintenance optimization. [1] G. J.
