Electric energy acquisition and operation management system and method based on platform zone centralized service terminal

Abstract

The invention provides an electric energy collecting and running management system on the basis of a station area concentrative service terminal, and a method thereof. The electric energy collecting and running management system is provided with a master system, a station area concentrative service terminal, an electric energy meter collector, a station area electric energy meter and a resident electric energy meter; the master system is in charge for services such as data collecting, processing, managing and analysing, output and the like; the running state of the system is monitored and undated; two communication channels such as GPRS or CDMA and RS232 are used between the master system and the station area concentrative service terminal; the station area concentrative terminal has the functions of distribution transform monitoring, electric usage site management, meter concentrator meter reading and the like; the downlink selects a RF narrowband wireless radio frequency data transmission/power carrier/RS483 interface to be communicated with the electric energy meter collector; meter reading task is sent down to the electric energy meter collector; the terminal collects the electric meter information read by various collectors and analyses all electric meter information; and the uplink transmits all data to the master system by the GPRS/CDMA channels.

Description

1. Technical field [0001] The invention belongs to the technical field of electric power automation, in particular to a power distribution automation system used in electric power systems. 2. Technical background [0002] Western developed countries began to actively carry out distribution automation work in the late 1970s. The purpose is to reduce operating costs, improve power supply reliability and quality, and win more users. In the 1970s, Japan began to implement high-voltage and large-capacity power distribution methods, and began to develop a method of relying on power distribution equipment and relay protection for automatic operation of distribution networks. The reliability of power grid power supply has been significantly improved. In 1997, Japan’s average annual 0.1 household power outages, with an average of 8 minutes each time, the reliability ranks first in the world. In 1994, the Long Island Power Company of the United States used 850 FTUs and wireless digit...

Problems solved by technology

At present, the power distribution monitoring equipment developed abroad is not fully suitable for the current situation of my country's power distribution network and the needs of power marketing management due to operating methods, technical differences and high prices.

At the same time, with the rapid development of computer technology, communication technology and electric power industry, many domestic manufacturers and research institutes have developed and developed various distribution automation products with certain technical application value, and realized a power consumption site mana
