Equipment Operation and Maintenance Management of Shanghai Power Distribution Network After Power System Reform

At present, China is in the process of reforming the electric power system. The reform of the power system has a significant impact on the investment and construction of power distribution network. Therefore it is indispensable to focus on fine management of the operation and maintenance of equipment. In this paper, the current situation of distribution network in China including Shanghai has been presented. Then, based on the influence of policy documents of power system reform, not only its impact on the operation and maintenance of the power grid enterprise and the distribution network equipment but also measures to enhance the economic benefit of distribution network has been discussed. Furthermore, by analyzing each equipment and the probability and severity of its defects according to the defect data in production management system (PMS), the methods of the whole life cycle cost (LCC) and the potential failure mode and effects analysis (FMEA) have been applied to analyze the operation and maintenance of the distribution network from the two aspects of the economy and reliability. Finally, focus on acceptance as well as operation and maintenance management measures in the current distribution network has been put forward.
