Intelligent substation relay protection training room

Abstract

The invention discloses an intelligent substation relay protection practical training room, and relates to the field of substation relay protection training. The intelligent substation relay protection practical training room is internally provided with cable grooves, a screen position ground plug, a direct current feeder screen cabinet, an alternating current feeder screen cabinet, an optical fiber switch screen cabinet, an analog circuit breaker screen cabinet, a clock synchronous screen cabinet and a plurality of mobile standby screen cabinets, the screen position ground plug is connected with the optical fiber switch screen cabinet through optical fiber, the screen position ground plug are connected with the analog circuit breaker screen cabinet, the direct current feeder screen cabinet and the alternating current feeder screen cabinet by cables correspondingly, and the optical fiber and the cables are laid in the cable grooves. According to the intelligent substation relay protection practical training room, flexible disassembly, mobility and interconnection of secondary equipment can be realized, protection of a whole test can be carried out, and intelligent station protection logic verification, integrated self-system debugging, secondary fault troubleshooting and the like can be carried out in the training room, and the training room can be used for protection of an intelligent substation, factory alignment of the integrated self-system, skills training of relay-protection employed persons and the like.

Description

technical field [0001] The invention relates to the field of substation relay protection training, in particular to an intelligent substation relay protection training room. Background technique [0002] Relay protection is the first line of defense for the safe operation of the power grid and the patron saint of the power grid. The rapid development of power system puts forward new requirements for relay protection. With the rapid development of electronic technology and computer technology, since the 1990s, my country's relay protection technology has entered the era of microcomputer protection. In recent years, relay protection technology has become Computerization, networking, intelligence, and integration of protection, control, measurement, and data communication continue to develop. The construction of UHV power grids and the engineering application of IEC61850 standard smart substations have injected new vitality into the development of relay protection technology. Ne...

Problems solved by technology

[0003] The substations that are actually put into operation are all live equipment, and it is impossible to carry out training for relay protection practitioners at any time. As a result, relay protection personnel only have theoretical knowledge in books, and the type of technical practice is single. It is difficult to get started in actual operation, and the time cost to achieve proficient operation is high; at the same time, there are many types of relay protection devices, and the models are different, so it is difficult to gather together. The trainees also have different requirements during the training process. However, at present The training room adopts the training operation of fixed devices, and a single training method is difficult to meet the needs of rapid development

[0004] In addition, before the smart substation starts construction, it is necessary to carry out the factory joint debugging of the secondary equipment, and because the construction unit lacks a place for debugging the secondary equipment, it is necessary to coordinate and transport the secondary equipment of all the manufacturers involved to the integrated manufacturer for the secondary equipment. Secondary equipment factory joint debugging, there are problems such as long equipment transportation time, long debugging cycle, etc.
