Global Data Exchange Method for Intelligent Distributed Feeder Automation

Abstract

The invention discloses an intelligent distributed feeder automatic global data exchange method, which limits the communication between two adjacent power distribution terminals, and each power distribution terminal interacts with its directly adjacent power distribution terminal to form a minimum interaction unit. The interaction unit is the smallest unit whose scale can be exhausted and information can be normalized, so it can be abstracted into a reusable smallest interaction unit class. The multiple minimum interaction units formed by the instantiation of the minimum interaction unit class are interconnected into a larger system through the shared power distribution terminal data proxy interaction, and iterates continuously in this way to realize the infinite scalability of the entire system. Therefore, this method solves the problems of unit stability and system scalability of intelligent distributed feeder automation in a balanced manner, and can provide strong support for its practical application.

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.
