Network windstorm restraining method of intelligent substation process level IED

Abstract

The invention relates to a network windstorm restraining method of an intelligent substation process level IED, and belongs to the technical field of electrical power system substation automation. According to the method, the network data transmitting and processing procedure of a merging unit device is utilized, a hardware module, a network drive module and an application module are controlled to receive and process message data, three-layer network protection is achieved, and the purposes that the data processing and device performance of other sets of an Internet port cannot be affected by the abnormity of data flow of a set of messages of the Internet port and the data processing performance of other Internet ports and the performance of the whole device cannot be affected by the abnormity of the data flow of one or several Internet ports are achieved. When the pressure of some sets of network messages of one Internet port is abnormal, other sets of messages of the Internet port cannot be affected. The possibility of device moving refusing or mistaken moving is eradiated under the bad network environment, and the reliability of device running is guaranteed.

Description

technical field [0001] The invention relates to a network storm suppression method of an intelligent substation process layer IED, and belongs to the technical field of power system substation automation. Background technique [0002] The intelligent merging unit is a new IED device in the smart substation. It is an integrated device of the smart terminal and the combiner. It is suitable for various primary switch bays or transformer bays in the smart substation. The two most important parts of the smart terminal unit are Functions: 1) Receive the control command from the process layer network or the direct control command from the relay protection device, and drive the corresponding outlet circuit to complete the control function of the primary equipment, and has the function of preventing misoperation. 2) Collect real-time data such as equipment location signals and alarm signals once, and publish them to the process layer network through GOOSE services. Due to the key po...
