Research On Distribution Equipment Condition-based Maintenance Management Of Shengzhou Power Supply Company

Shengzhou power supply company has been using the preventive test and maintenance mode of regular power outages for many years,as an important means to supervise and evaluate the operation status of equipment.However,with the development of economy,the equipment of the power grid is increasing rapidly.The original maintenance mode has many problems,such as more power outages,large manpower and material resources,long time interval between maintenance and lack of pertinence.Condition maintenance work can be applied to many live detection technology,operation of power equipment to carry out experimental work in the premise of ensuring the level of technical supervision to improve the maintenance efficiency,saving the cost,is the inevitable direction of development and trends in maintenance mode.First of all,the development process and characteristics of equipment maintenance mode at different stages are studied,and the application and development direction of equipment maintenance are analyzed.Shengzhou city power grid equipment comprehensive survey of the company,maintenance mode and maintenance power,starting from the application of on-line detection technology,change the mode of maintenance outage and compared,taken by extending or even replace regularly pre-test equipment overhaul period and reduce the number of solving the disadvantages and problems of periodic preventive test maintenance mode,solve the shortage of maintenance the difficulties.At the same time,the establishment of state maintenance organization structure,standardization process and safeguards system,do a good job of data acquisition,state assessment,fault diagnosis and maintenance decision of each link,to test results to guide the specific maintenance decision.Based on the reliability of the failure rate model,based on the economy of the maintenance income model and the three aspects of the decision making and constraint conditions of the maintenance,a number of criteria for the maintenance decision are constructed.The necessity and trend of decision support system are put forward.It provides a scientific and effective way for the orderly maintenance of condition based maintenance and the decision of maintenance.
