Intelligent distributed feed line automation global data exchange method

Abstract

The invention discloses an intelligent distributed feed line automation global data exchange method. In the method, the communication is restricted between every two adjacent power distribution terminals, and each power distribution terminal and the directly adjacent power distribution terminal interact to form a minimum interaction unit which is exhaustible in scale and normalizable in information, so that the minimum interaction units can be abstracted to form a minimum interaction unit class which can be repeatedly used. The multiple minimum interaction units formed by instantiation of the minimum interaction unit class are interconnected to form a larger system through a common power distribution terminal data agent interaction manner, and are continuously iterated in the manner, so that the whole system can be infinitely scalable. By employing the method, the unit stability and system expandability of intelligent distributed feed line automation are achieved through a balance manner, and forceful supports can be provided for the practicability of the intelligent distributed feed line automation.

Description

technical field [0001] The invention relates to an intelligent distributed feeder automation global data exchange method, which belongs to the technical field of distribution network automation. Background technique [0002] The traditional centralized feeder automation collects power distribution terminals and transmits data vertically to the remote centralized control center, and the control center centrally completes the feeder automation function. Due to the long vertical data transmission time and poor real-time performance, the time to restore power supply in non-faulty areas is tens of seconds. With the improvement of power supply reliability requirements, intelligent distributed feeder automation that can shorten the recovery time of power supply has become a popular technology. This technology divides the functions of centralized feeder automation and deploys them separately to multiple independent power collection and distribution In the terminal, the collection a...

Problems solved by technology

The simplest data interaction scheme is that each power distribution terminal performs data interaction with all other power distribution terminals, but this data interaction method has the following problems: 1. The amount of data interaction is large, and there is a lot of useless information exchanged, which aggravates the network and The load of each intelligent power distribution terminal; 2. The amount of data that needs to be interacted and processed by the power distribution terminal varies with the scale of the project, so it is impossible to realize the abstraction of the feeder automation function of the power distribution terminal and achieve reusability; 3. When composed of distributed When any change occurs in the topological relationship of multiple power distribution terminals in feeder automation, all power distribution terminals need to be redeployed, and local modification and local redeployment cannot be realized.
