Problems solved by technology

With the development of the economy, the upgrading and transformation of distribution network line equipment continues to deepen, and the contradiction of using different communication protocols for intelligent distributed equipment of different manufacturers has become increasingly prominent. After upgrading the same line or ring network line, if you want to maintain the intelligent distributed function, you must use the equipment of the original manufacturer. Or replace the entire line of intelligent distributed equipment, which not only seriously affects the upgrading and transformation process of distribution network line equipment, but also brings huge economic losses
At present, the communication protocols adopted by the intelligent distributed technology of different manufacturers are different, and the information cannot be transmitted correctly between each other, so that the switches cannot cooperate correctly. This situation seriously affects the speed of the upgrading and transformation of the distribution network.

Embodiment 1

[0055] This embodiment provides a single intelligent distributed power distribution terminal control method based on peer-to-peer communication, including the following steps:

[0056] 1.1. Establish an intelligent distributed single-node model for peer-to-peer communication, such as figure 1, the switch SW needs to be connected with other switches on both sides, so the connection areas on both sides of the switch SW are defined as the M side and the N side respectively. The nodes of each branch can be expanded with reference to this model. For the first switch and the last switch, there are only 1-side nodes on the M side and the N side. In order to ensure that the intelligent distributed function only operates once in a system failure, the intelligent distributed power distribution terminal is designed with a fault isolation charging and discharging state. When the system fault is isolated, the intelligent distributed power distribution terminal is designed to restore the ...

Abstract

The invention discloses a single intelligent distributed power distribution terminal control method based on peer-to-peer communication. Through the peer-to-peer communication method, the intelligent distributed switches of different manufacturers can be correctly matched, the faulty switch is found, and the fault point is isolated in time, so as to The most economical mode speeds up the upgrading of the distribution network, improves the safe operation factor of the power grid, and ensures reliable power supply to users.

Description

technical field [0001] The invention relates to the field of power grid operation and maintenance, and more specifically, to a control method for a single intelligent distributed power distribution terminal based on peer-to-peer communication. Background technique [0002] In recent years, the scale of my country's power grid has been continuously expanding, and the automation level of the power grid has been continuously improved. Therefore, intelligent distributed distribution network automation technology has been widely used. Each manufacturer has its own independent set of communication protocols. At present, the intelligent distributed feeder switch of the same line or ring network line adopts the equipment of the same manufacturer. With the development of the economy, the upgrading and transformation of distribution network line equipment continues to deepen, and the contradiction of using different communication protocols for intelligent distributed equipment of diff...
