Construction And Design Of Substation Power Balance Analysis System

In order to improve the level of power system economic operation and to enhance the electrical energy utilization efficiency and effectiveness,power grid enterprises attach importance to the management of line loss case and need to a set of applicable to the electric power enterprise power balance analysis system,this thesis designs a power oriented enterprises to solve the line loss management of power balance analysis of the client software system.The thesis mainly provides a solve the power grid equilibrium statistical analysis of design thinking and frame,design of substation electric energy balance analysis system with Excel VBA language based design and development,data on the system implementation approach,and the realization of system development needs the running environment of the system,calling data,analysis of statistical functions,the functions of communication and report output design and analysis.Substation power balance analysis system design includes the analysis based on the principle of system,functional structure design,process design,interface design,network design and database design.The key system of statistical analysis function design and function module design.The statistical analysis function design covers the grid within the framework of the substation,cross line and distribution network design part;function module design part of the system management,statistical analysis,report output,four module data management module design;in addition to statistical analysis function and module management of the two part of the design,but also on the message log function,query function,client and other functions are designed in detail.The design scheme and the corresponding design,fit for electric power enterprise reality,integrated power system energy balance analysis index data,provide reliably solve the line loss management of substation and power balance analysis scheme for users of the system.System overall design effect conforms to the requirements of power user electric energy balance analysis,through the transformer substation power balance analysis system research and development,the substation power balance analysis simple,systematic,automation,reduce the workload of the power supply company staff,improve work efficiency.
