Integrated control system for electricity distributing and metering

Abstract

The invention relates to an integrated control system for power distribution measurement. The integrated control system of the invention comprises a main control module which consists of a central processing unit and a memory unit used for storing the data of various parameters, and a measurement module, a meter reading module, a control module and an LCD display module which are all connected with the main control module, wherein, the measurement module is used for taking the samples of voltage signals and current signals of a power distribution circuit and an electricity use circuit and sending the signals to the central processing unit after the signals are processed by a digital signal processor; the meter reading module is used for reading the electricity data of an electrical energy meter; the control module is used for controlling the switch-in and switch-out of the power distribution circuit and the electricity use circuit and also detecting the implementation situation. The integrated control system for power distribution measurement of the invention integrates the functions of a high-precision three-phase electrical energy meter, a meter reading concentrator, a distribution and transforming measurement monitoring terminal, a power quality monitoring terminal and a load management terminal in an electric power system into a whole, and also spares complex circuits and repetitive communication modules for the communication among each equipment and between each equipment and a main control station, thus saving cost and ensuring convenient maintenance.

Description

technical field [0001] The invention relates to power distribution, metering, monitoring and control equipment for power systems, in particular to a high-precision three-phase electric energy meter, a meter reading concentrator, a distribution transformer measurement monitoring terminal, a power quality monitoring terminal, and a load management terminal. distribution metering integrated control system. Background technique [0002] In order to facilitate the management of the power system, usually in a certain area, such as a residential area or an office building, a concentrator is set up to collect the metering data of each metering terminal in the area, and distribution transformer monitoring equipment is required to monitor the working conditions of the transformer. Power quality monitoring equipment and load control terminal equipment monitor and control the operation of the power grid. Although these devices can be placed centrally and managed in a unified manner, a ...

Problems solved by technology

Although these devices can be placed centrally and managed in a unified manner, a large number of communication lines still need to be laid between each device to ensure mutual auxiliary work and coordination, and each device must be equipped with a dedicated communication interface circuit to connect to the uplink control master station. Cause duplication of resources, and its repair and maintenance are difficult and costly
