Centralized control and centralized copy device supporting to observe and control network in distributing net platform region

Abstract

The invention relates to a user side centralized reading and centralized controlling device of a power network distribution line. The distribution network generally adopts a power line which is lower than kilovoltage, the demands of the information management to the large consumer and the distribution transformation can be basically met in the network distribution, but for the public low voltage users and power supply area which are in enormous quantity and widely used, and effective information management method is deficient. A novel centralized reading and centralized controlling device is led in the invention and is composed of a CPU, a storage, a user input interface, a user controlling interface, and a network distribution area network measuring and controlling interface, after networking, a distribution transformation area is realized to be used as a management unit, and the information management is extended to each user in the area. Because the device is applied to joint the network, the novel functions of remote meter reading, the remote on and off of the power source of the appointed user, the remote alarming according to the electricity of the user, the controlling to the electric quantity user according to the user load and the power supplying according to the prepaid charge can be realized.

Description

Technical field [0001] The patent of the present invention relates to the user-side device of the measurement control and information management system of power transmission and distribution network lines. Background technique [0002] The distribution network generally refers to power lines of 10 kV and below, as well as equipment and facilities such as power transformation, power distribution, protection, and control in the lines. An important task for millions of households. [0003] The most important equipment in the distribution network is the transformer, which usually changes from 10 kV to 400 volts (to the user side, it is generally called three-phase 380 volts or single-phase 220 volts). According to different users, it is divided into exclusive power supply for large users Dedicated transformers and public transformers that supply power to sporadic users, the entire scope of power supplied by a public transformer is called a power supply area, and the power suppl...

Problems solved by technology

Its advantage is to buy first and use later. The power supply company has economic benefits and avoids the difficulty of charging. The disadvantage is that it does not know the user's electricity consumption information at all. If it is too dependent on this method, the power supply staff will not come to check. Stealing electricity can only be let go
