Embodiment Construction

[0014] The invention is a set of power load monitoring system which adopts wireless special network to integrate management, load monitoring, remote meter reading and anti-stealing.

[0015] 1. The main functions realized by the system: In the central control room, users (monitoring terminals) can be divided into different work groups according to user levels or regions to facilitate group operation; the system has a remote control function, which can be remotely controlled by groups or individually Remote control, the central control room realizes the power limitation program for users through remote control; the system has telemetry functions, which are mainly divided into patrol and selective measurement, that is, automatic remote measurement of each user's information or automatic remote measurement of specific user groups. The remote measurement is: current, Voltage, active power, power factor, active power, reactive power, overload trip times, etc.; the system has remote sig...

Abstract

The invention provides a power load monitoring system realized by wireless communication aimed at the characteristics including many users, wide range, dispersion and low information amount of presentpower load monitoring communication, and aims at solving the technical problem that a present load monitoring system is low in communication efficiency and single in function. The system comprises acentral control room, and the central control room is in bidirectional communication with power load monitoring terminals of primary and secondary bidirectional terminals via a wireless relay station.The power load is monitored remotely and intelligently via a wireless private network, and the system is capable of high-grade management, electricity larceny prevention and remote meter reading. Viathe power load monitoring system, scientific decisions can be made in the aspects of load prediction, plan design and power production plan of the power system, and the power load monitoring system is helpful for safe and economic operation of the power grid.

Description

Technical field [0001] The present invention relates to power load monitoring technology, in particular to a power load monitoring system realized through wireless communication. Background technique [0002] Most of the existing power load monitoring systems were built in the 1980s, and their main function is to balance and control the power load, but this single-function system can no longer meet the requirements of modern power management. The existing power load monitoring system is mainly divided into RS-485 bus mode implementation, low-voltage power carrier mode, public telephone network and wireless data radio communication from the perspective of communication methods, and they have their own advantages and disadvantages. The RS-485 bus method has strong anti-interference ability, but the transmission distance is relatively short, and the number of terminals is limited; the low-voltage power carrier method does not require additional communication lines, but the anti-elec...
