A Study On The Application Of Live Detection And On Line Monitoring Technology In Zhoushan Powr Grid

The Zhoushan islands locates in the estuary of the Yangtze River,which has been recognized that the traffic is inconvenient and the grid structure is weak.Because of the sea barrier,it is difficult for personnel to arrive at the scene in time.Compared with the mainland power grid,they cannot grasp the critical data of the error operation equipment for the first time.Since 2009,the company has started to implement the maintenance mode,which focuses on the status of online monitor and electric test.Uploading the real-time online monitor data,combining with the artificial charged detection regularly,the staff can monitor the equipment running status at any time in the office.However,due to configuration plan of the provincial company's online monitor device and the electric test plan is short of pertinence for the actual situation in the island area,therefore,this thesis mainly studies and improves on the application of these two kinds of detection technology in Zhoushan power grid.This thesis firstly analyzes the geographical features of Zhoushan power network,introduces the research background and significance,and reviews the development and current situation of online detection monitor technology with line detection and application in Zhejiang power grid.The second chapter summarizes the principle and application of online detection and online monitor technology,mainly about the UHF detection method,ultrasonic detection method,infrared detection method,DGA method and so on.The third chapter gives a brief summary of the characteristics of Zhoushan power grid and the application status and problems of online detection and online monitor technology in Zhoushan power grid.The fourth chapter puts forward the configuration scheme of online monitor device that is suitable to Zhoushan power grid.The online monitor device for the key equipment of the transformer substation in the island area is strengthened,and the corresponding electrified inspection program is optimized,which appropriately prolongs the detection period and reduces the pressure of manual operation.The fifth chapter combines the actual project cases and introduces the solutions to the integrated online monitor system that is suitable for island regions.This part refers to the actual case that the author encounters in the work,and analyzes the rationality and superiority of the scheme.In the end,the paper summarizes the application of the integrated electric detection and online monitor technology in Zhoushan power grid,prospects the future work and put forward some shortcomings.
