Energy efficiency management system based on intelligent transformer area

Abstract

The invention relates to an energy efficiency management system based on an intelligent transformer area. The energy efficiency management system comprises a system master station, a transformer area sub meter, an intelligent centralized control device and an intelligent interactive terminal, wherein the intelligent centralized control device is installed in a transformer area; the intelligent interactive terminal is installed on a user side; the transformer area sub meter is an intelligent ammeter provided with a ZIGBEE transmission module; the intelligent centralized control device comprises an ammeter concentrator, an interactive terminal concentrator, transformer area wireless communication equipment, reactive-load compensation equipment, intelligent communication equipment and a distribution transformer monitoring terminal; compensation modes can be adaptively selected by an SVG (Scalable Vector Graphics) digital control system, so that a main circuit can adapt to external connection. According to the energy efficiency management system, an information technique, an electronic technique and an automated technique are applied to establish a stable and reliable communication network and an advanced master station and background integrated management system. By using the energy efficiency management system, the intelligent level of a power supply area is improved, and online monitoring of an operating state of the transformer area is realized; the long-standing problems of harmonic suppression and three-phase imbalance of a rural power network are solved; the loss of the transformer area is reduced; the user initiative is mobilized, and energy conservation and loss reduction are promoted.

Description

technical field [0001] The invention relates to an energy efficiency management system based on an intelligent station area, and belongs to the technical field of energy efficiency management and comprehensive application of information technology. Background technique [0002] In rural areas of our country, there are many phenomena such as large line loss of low-voltage power grid, unbalanced three-phase, large harmonic content, low degree of intelligence, and little interactive information between the power sector and users. These problems have not been fully resolved so far. And with the implementation of tiered electricity prices in China, how to build an interactive platform between the power sector and users, provide users with effective power-saving solutions, and cut peaks and fill valleys to achieve efficient energy use has become an urgent problem to be solved. Contents of the invention [0003] The technical problem to be solved by the present invention is to p...
