Research And Implement Of Monthly Line Loss Rate Volatility Analysis System Of Electric Power Enterprises

Line loss rate is a comprehensive technical indicator that reflects the reasonable degree of electric power network and operation mode,power supply enterprise management level and power new technology application level. The line loss rate historical dates currently show monthly line loss rate of provinces and cities fluctuations greatly, even to be negative in some historical month of the year,make the statistical line loss rate don't reflect the power supply enterprises product and management, bring great inconvenience to product management analysis and planning of the production technology department of power supply enterprise.According to the scientific management work need of the electric power enterprise monthly line loss rate, after the theoretical analysis, practical research and the monthly loss rate statistical processing, this paper develops a set of line loss management database and line loss rate self analysis software, which provide a scientific basis for the line loss rate management.The main work of this paper includes: (1) research of the potential factors of line loss rate management influence on line loss rate fluctuations, analysis of the calculation method of various management factors contribution to line loss rate fluctuation based the line loss management process. (2) research of the potential factors of electric load composition influence on line loss rate fluctuations, theoretical analysis of the calculation method of various technical factors contribution to line loss rate fluctuation. (3) research of the potential factors of the electric power network change influence on line loss rate fluctuations, theoretical analysis the various electric power network parameters on approach and calculation method of line loss rate fluctuations.(4)taking Microsoft Visual C++ as development environment and taking Microsoft Access 2003 as background database development software, joint develop a set of line loss management database and line loss rate self analysis software, which includes line loss rate management database, line loss rate statistical analysis system and line loss rate loss rate fluctuation reason analysis system.Through hardware and software environment comprehensive test, test that the project is fully functioning includes line loss rate management database, the analysis of power supply and power sale and line loss rate, the automatic generation of a line loss rate analysis report file etc. The software satisfies demand of enterprises scientific management to the power line loss rate requirements of daily work.
