Problems solved by technology

However, the development of the current protection system is relatively lagging behind and cannot fully keep up with the speed of fault spread in the smart distribution network. Therefore, how to quickly and accurately analyze the fault of the smart distribution network, and isolate and restore it has become the focus of current research.

Abstract

The invention relates to an intelligent power distribution network information physical fusion protection system and method. The system comprises an intelligent power distribution network physical information acquisition layer, a computer network transmission layer, a data analysis layer and a protection equipment execution layer, the intelligent power distribution network physical information acquisition layer is used for acquiring power data of the power distribution network; the computer network transmission layer is used for transmitting the acquired data state information of the power distribution network to the data analysis layer by using a computer network; the data analysis layer is used for detecting whether the power distribution network is abnormal or has a fault by using the acquired data state information of the power distribution network, continuing fault positioning once the fault is detected, and sending a fault isolation command to protection equipment of the protection equipment execution layer; and the protection equipment execution layer is used for receiving the fault isolation command of the analysis layer, controlling isolation equipment, isolating fault nodes and recovering normal power distribution operation as soon as possible. The fault of the power distribution network can be quickly and accurately analyzed, the processing scheme can be given, and quick recovery of power supply operation is realized.

Description

technical field [0001] The present application relates to the field of distribution network technology, in particular to a cyber-physical fusion protection system and method for an intelligent distribution network. Background technique [0002] Power supply includes a series of processes such as power generation, power transmission, and power distribution, among which power distribution is a relatively important link. The main task is to distribute power energy to users according to user needs. With the development of science and technology, the link of power distribution is gradually developing in the direction of intelligence and automation. In this way, while improving the efficiency and quality of power distribution operations, it also makes the power distribution system more closely and deeply integrated, which leads to the fact that once one of the nodes fails, the entire power distribution system will face paralysis, so the power distribution system The equipment wil...
