Design And Implementation Of Maintenance Management Information System For Substation Operation Equipment Of Power Supply Company

The substation equipment should be overhauled,in order to remove the possible hidden dangers of the equipment and reduce the probability of accident in the substation operation equipment.At present,with the development of economy and the enlargement of the scale of the power network,the traditional way of equipment maintenance can no longer meet the development of the current situation.Changing the way of equipment maintenance has become a necessity.The condition based maintenance of equipment is a new method of maintenance,which has been formed after accident maintenance and rugular maintenance.The substation equipment maintenance information management system from the introduction to today,have improved and developed greatly,but there are some problems: one is the software behind the choice of procedure gradually can not meet the information requirements;two is open enough,the team set less,to the repair work must not bring three is the most uncertain;substation maintenance information management system have not been able to consider the establishment of the mathematical model of the problem as a whole,it will cause it has some out of touch with the substation maintenance work.Equipment condition maintenance,mainly based on the on-line monitoring data,historical data and related data of similar equipment,evaluate equipment running status,find the hidden danger of the equipment fault in advance.The development of condition based maintenance is mainly based on two considerations: first,in order to meet the requirements of power supply reliability;the two is to improve the quality and efficiency of electrical equipment maintenance,so as to achieve the purpose of ensuring system safety.The substation equipment maintenance information management system from the introduction to today,have improved and developed greatly,but there are some problems: one is the software behind the choice of procedure gradually can not meet the information requirements;The two is that theopenness is not enough and the group role is set less,which brings some uncertainty to the maintenance work.Three,substation maintenance information management system have not been able to consider the establishment of the mathematical model of the problem as a whole,it will cause it has some out of touch with the substation maintenance work.Considering the above factors,a reasonable information management system for substation operation and repair equipment is designed and developed for reasonable maintenance of substation operation equipment.The operation data of the electric equipment maintenance information system operation monitoring collection of substation equipment,and these data and parameters are judged by the expert diagnosis module,that is currently running the substation equipment whether the normal operation of the conclusion,once found the equipment problems,must develop the equipment maintenance scheme to solve the problem of the.This paper first gives a brief introduction of the power company substation operation status of equipment maintenance,analyzed the domestic and foreign research status and development trend of state maintenance,and a reasonable choice of the substation equipment maintenance information management system development mode,modeling language and technical support.Secondly,from the economic feasibility,technical feasibility and other aspects of the development of the system must,at the same time,the system's functional requirements,performance requirements and other aspects of the further determined,according to the requirements put forward the overall design of the system,and introduces the design of each module.At the same time,the function requirements and performance requirements of the system are further determined.According to the needs,the overall design plan is proposed,and the design of each module is introduced in detail.Finally,after testing the system,we can confirm that the system can achieve better management of the substation operation equipment and improve the efficiency of the staff.Compared with the traditional way ofmaintenance,the system is more practical and economic value.
