Abstract

The system includes following parts: control center connected to Internet and control terminal, and through Internet, control terminal is able to connect to the control center; mobile communication network connected to Internet; communication terminal connected to mobile network wirelessly; terminal for monitoring feed line connected to communication terminal and electric devices respectively. Through Internet, control terminal sends control command to the control center. Through Internet and mobile network, the control center sends control command to communication terminal, which transfers the received command to the monitoring terminal. The monitoring terminal sends monitored state information at site of power distribution to the communication terminal, which sends the information to control center through mobile network and Internet. The control center returns the information bake to control terminal. Advantages are: short building period, easy of upgrading etc.

Description

technical field [0001] The invention relates to a power distribution system in the electric power industry, more specifically, to a power distribution automation system used in the electric power industry. Background technique [0002] Distribution automation refers to the use of modern electronics, computers, communications and network technologies to integrate online and offline data, distribution network data and user data, power grid structure and geographic graphics to form a complete automation system.
