Design And Implementation Of Power Marketing Decision Support System

With the in-depth reform of China's power system,people's requirements for the production and operation of the power industry are getting higher and higher.In order to make the operation of the power grid more stable and reliable,the State Grid has fully carried out the construction of power informatization.Under such a large environment,traditional power companies must use information technology to improve the efficiency of production management and operation and maintenance in order to keep up with the development trend of the power industry.In the production management and operation and maintenance of power companies,a lot of basic data and business data are generated,especially substations are the core part of the power system.During the transmission or distribution process,the state stability of the substation equipment will be Directly affect people's electricity life.Therefore,it is particularly critical to maintain the stability of the operation of the substation equipment.In order to accurately determine the stability of the operation status of the substation equipment,usually in the operation and maintenance of the substation,the method is to obtain the operation status data of the substation equipment,and conduct an experimental analysis to determine the equipment Whether the running status is normal.In this paper,the operation and maintenance of a substation of a power company is selected as the research object,combined with the actual operation and maintenance work of the power company,the advanced development technology is used to design and implement the intelligent analysis system of substation operation and maintenance integrated data.Provide the necessary equipment status analysis data for the operation and maintenance of the substation equipment of a power company.The main research work of this thesis is as follows:(1)Research the related theoretical technology of the analysis and development of substation operation status data,and summarize the current status of the analysis of the operation status data analysis of substation equipment at home and abroad by referring to the literature.Relatively mature,China's power industry has already carried out the construction of intelligent operation and maintenance,and there are many mature system architectures that can be used for reference.(2)On the basis of theoretical research,through in-depth on-site business demand survey,and UML technology to conduct a demand survey to comprehensively summarize the needs of a power company's substation equipment operating status data analysis.Based on the demand analysis,the paper uses the popular MVC framework to design the substation operation and maintenance integrated data intelligent analysis system architecture,and uses lightweight SSH technology to implement the architecture.In the database design stage of the system,this thesis uses a powerful relational database SQL Server database system.And detailed design of the database concept and logical structure.(3)The paper uses JAVA language to develop system functions and interfaces,and implements the three-layer architecture of user interaction layer,business logic layer and data layer of the power enterprise substation operation status data analysis system.The system mainly includes status acquisition monitoring and status analysis Five functions of diagnosis,operation status evaluation,status risk assessment and fault status early warning.At present,the system has been successfully applied in the daily operation of a power company's substations.The system operates stably and meets the current requirements of substation equipment operation status monitoring and data analysis.Not only does it bring new informational methods to the operation and maintenance of the power company's substations,and improves work efficiency,but the data obtained by analysis can provide the management personnel of the power company with decision-making basis for substation production operation.
