The Study Of The Uniform Maintenance Management Scheme For 35kV Substation Automation System In Gansu's Countryside Electrical Grid

Substation synthetic automation system is kind of system whose secondary devices have been functionally combined and optimally designed. With the utilization of the advanced computer technology, modern electronic technology and signal processing technology, Substation's main equipment and the transmission line can be monitored, metered, controlled and protected automatically by computer. For the operation of substation safely reliably, synthetic automation system is kind of important guarantee in technique.Until now, in Gansu Province's countryside electric grid, almost four hundred 35kV substations have been on service, it enhanced the level of the automation operation and took an active part in grid's safety and stabilization. But at the same time, the 35kV substation's synthetic automation systems in Gansu countryside electric grid have exposed some problems, such as too many kinds of equipments, the quantity of the equipment is too large, the compatibility of the software and hardware is not good and difficult to realize interface. On some levels, it affects the substation's safely, reliably and stably operation.To handle the problems during the maintenance of the automation system, this, article based on the theory of substation synthetic automation system and operation management, coupled with the real situation of the Gansu's countryside electric grid, comprehensively analyzed and demonstrated the whole province's necessity and feasibility of the maintenance management scheme of the substation synthetic automation system, and presented the whole framework. From the point of the keeping the investment and safety of the autornation system, the research is very valuable and magnificent.First, the article analyzed the basic principle and structure of the 35kV substation synthetic automation system, mainly compared the structure mode of the automation system in substation, summarized main function and structure of the 35kV substation synthetic automation system in Gansu countryside electric grid and the inner telecommunication mode including the main operation system; Based on the research on the 35kV substation automation system, in technique, the analysis of the feasibility is presented including the classic faults met in the substation automation system, the performance of different products and substitution of the equipment ; A uniform...
