The Design Of Line Loss Fine Management System According To Line And Power Supply District

Power consumption and line loss rate is the power grid enterprises core managementindex， is directly reflect the power sector income and cost the most important data，especially the loss of each link loss rate index in power network operation， embodiesthe production， scheduling， marketing and other core business management level.Attention to the electricity sector consumption and line loss management oflong-term，strengthen the organization system，and constantly improve the meteringdevice， carry out the construction of information system， a strong guarantee for theelectric quantity and line loss management. The power company has always adheredto the "unified leadership，graded management，division of labor" principle，by thedevelopment of centralized collaborative ministry， the professional sector， theestablishment of a complete consumption statistics and line loss management system，normalized to carry out power exchange， power plant， power supply， electricitysales Internet gateway and other statistical work and power line loss "four"management， index of line loss management， theoretical line loss managementwork.This paper first construction of line loss management system carried out a detailedneeds analysis， and then to the system construction to give a reasonable solution，the main content of the "three sets of five" overall development strategy under theguidance of the general construction principle， the construction of line lossmanagement system as the system construction， system integration， unifieddevelopment index data standardization.Technical standard of this project to follow the people’s Republic of China electricpower industry standard DL/T686-1999"power loss calculation guide" and IEC61803："Determination of Power Losses in High-Voltage Direct-Current (HVDC)Converter Stations"， part of the contents and the formula of removal and adaptedfrom the China Southern Grid Corp "line loss theoretical calculation technologystandard". This paper will make full use of the existing power company technicalachievements and data resources， integration and power loss generated information about the process， the realization of transmission and distribution， with the processof electricity automatic collection， monitoring， and scientific line loss calculationbased on the model， to realize the automatic generation and analysis of various indexof line loss， prevent unknown loss， reduce the management loss， make the lineloss management mode by the direct management of the results to process real-timemonitoring， can refine the help of line loss management of power companies and thedeep push， improve the overall management level.Due to the improvement of management optimization， line loss management systemput into use，in addition to the main social benefits，will also bring certain economicbenefits for the power company.
