Problems solved by technology

At present, the development of rural distribution networks is relatively lagging behind, some lines have small cross-sections, large power supply radii, low reactive power compensation ratios, high losses in lines and distribution stations, and "three rates" (line loss rate, voltage pass rate, Reliability of power supply) needs to be solved urgently. Actively carrying out comprehensive energy-saving transformation of distribution network has very important practical significance for improving the "three rates" of distribution network

Abstract

The invention provides a power distribution network monitoring and management system which comprises an energy efficiency terminal device installed on site, a preposed server and an energy efficiency service platform. The energy efficiency terminal device is responsible for energy efficiency measurement of an installation spot, also conducts reactive compensation automatically as needed, improves the power factor and voltage of the installation spot, and provides a data source for the system. The preposed server is used for collecting operation information of the energy efficiency terminal device and realizing information interaction between the energy efficiency service platform and the energy efficiency terminal device. The energy efficiency service platform takes charge of data processing, service application and data interface service for a distribution automation system (DMS), an electricity utilization marketing system (AMI) and a production management system (PMS), wherein a high-volume database is introduced in the data processing to realize information storage, the service application comprises the functions of monitoring, analyzing, managing and evaluating energy efficiency, and a data bus is used for realizing reliable message transmission when the multiple systems are in interconnection in the data interface service. The power distribution network monitoring and management system has great guide significance in energy conservation and loss reduction improvements and economic operation of medium and lower voltage power distribution networks.

Description

technical field [0001] The invention relates to the field of distribution networks, in particular to a distribution network monitoring and management system. Background technique [0002] The distribution network has always been a weak link in the development of the power grid. At present, the development of rural distribution networks is relatively lagging behind, some lines have small cross-sections, large power supply radii, low reactive power compensation ratios, high losses in lines and distribution stations, and "three rates" (line loss rate, voltage pass rate, The problem of power supply reliability needs to be solved urgently. Actively carrying out comprehensive energy-saving transformation of distribution network has very important practical significance for improving the "three rates" of distribution network. [0003] Comprehensive management of the "three rates" of the distribution network, the access and consumption of new energy, the management of energy forms,...
