Station-domain protection system of intelligent transformer station and function debugging method of system

Abstract

The invention relates to a station-domain protection system of an intelligent transformer station and a function debugging method of the system. A station-domain protector is mounted between an integrated application server and monitor host and a central switch of a process layer, the station-domain protector is networked with the integrated application server and monitor host via MMS messages, and the integrated application server and monitor host is networked with the central switch of the process layer via GOOSE and SV messages. The debugging technology as well as single debugging, network debugging and group transmission methods of station-domain protection of the new generation of intelligent transformer station are included, the workload of equipment maintenance is reduced, wire arrangement is greatly reduced, wiring is simple and convenient, the installation efficiency is effectively improved, the whole construction period is shortened, and the operation stability of the system is improved.

Description

technical field [0001] The invention belongs to the field of intelligent substations, and relates to a new generation of intelligent substation protection device and a function debugging method, key technical debugging points, in particular to an intelligent substation protection system and a function debugging method. Background technique [0002] As a new thing of the new generation of smart substation, station domain protection performs the main protection and backup protection functions within the substation, and is responsible for transmitting these intermediate measurement results to the upper-level wide-area protection unit, accepting and executing the decision-making results of the wide-area protection. The station area protection can be connected to the wide area protection system as a substation, which can not only protect the power equipment of the whole station, but also cooperate with the wide area protection system to protect the safety of the regional power gri...

Problems solved by technology

[0003] However, at present, smart substations are still in their infancy in my country. Although the State Grid Corporation of China has proposed commissioning specifications for related smart substations, the station domain protection devices and functional debugging methods for the new generation of smart substations are still basically in a blank stage.

After searching the literature on the keywords of "smart substation*station domain protection*debugging", the technologies related to this patent mainly include the following aspects, but it does not involve the specific methods and key technical points of the station domain protection device and functional debugging. Unable to guide the development of specific debugging work
