Distribution network line loss management system

Abstract

The invention provides a distribution network line loss management system. The system comprises an operation management subsystem, a standard dictionary database subsystem, a network model management subsystem, a distributed network loss calculation subsystem, a distribution network simulation analysis tool subsystem and a data query subsystem. The operation management subsystem is used for dividing power grid management regions, setting nodes and configuring operation authorizations, the standard dictionary database subsystem is used for setting voltage grade, line type and distribution transform type information of a distribution network and completing power grid model design, the network model management subsystem is used for managing power grid models and setting plant station, feed line and substation region information required by power grid simulation calculation, the distributed network loss calculation subsystem is used for carrying out distribution network loss calculation, the distribution network simulation analysis tool subsystem is used for achieving calculation and analysis under normal operation and various fault conditions of a transmission and distribution network, and the data query subsystem is used for providing a data query function. By means of the system, comprehensive computer management for line loss of region division, voltage division, element division, line division, substation region division, and subsystems, electric quantity balance of a bus, main transformer loss, and line loss small indexes is achieved, the line loss management level is improved, and working efficiency is improved.

Description

technical field [0001] The invention relates to the technical fields of electric power systems and computers, in particular to a statistical comprehensive management system for electric energy line loss of a power network. Background technique [0002] The power loss rate of the power network (hereinafter referred to as the line loss rate) is an important comprehensive economic and technical index of the power system, which reflects the level of power network planning and design, production technology and operation management. According to the national policy of "emphasizing both resource development and conservation, and putting conservation first", the power system has invested a lot of manpower, material and financial resources to reduce the line loss rate and improve economic benefits. However, line loss statistics and management involve many links and data, are related to multiple economic benefits, and have many human factors. [0003] In the prior art, there are many...
