Research On Condition Monitoring Applications In Shanghai Power Grid

With the power system towards the development of UHV era of highly integrated, highly automated, reliable operation of the electrical system is particularly important to the traditional repair techniques can not meet the requirements of the development. Traditional maintenance equipment on a regular basis stops the service, not only to produce the equipment suspended service to a lack of planning, lack of maintenance projects targeted, but also result in the maintenance costs accounted for the proportion of the cost of electricity has continued to improveIn recent years, the state detection in the power system is increasingly subject to the attention of management, research, operations and engineering and technical personnel. State detection technology through online, offline, and other high-tech means of detection, electrical equipment without suspended service, charged to diagnose the health of the different devices.This paper briefly describes the history of the development of the state detection technology and trends, and cited a variety of grid device state detection method. Detection example described by the state of grid equipment testing methods using a variety of state run power equipment health diagnosis and the role of the early incidents are identified and addressed, and proposed state detection technology in the future improvement ideas.State detection technology for the safe operation of power equipment to provide a strong protection to rule out potential causes of accidents, the optimization of the maintenance cycle has obvious advantages, convenient to the Shanghai grid operation and management, the realization of scientific and intelligent managementis of great significance; to improve the accuracy of grid operation and maintenance management, tight, fast, has a significant role in promoting.
