Problems solved by technology

The intelligent unit and the circuit breaker control cabinet each maintain the original electrical secondary circuit. The secondary circuit is still very complicated and cumbersome, and has not been simplified and optimized.
Operation and maintenance are still relatively complicated
[0004] 2) A large number of high-protection grade outdoor cabinets need to be configured on site, which increases project investment and site
[0005] 3) The interoperability is not good. The intelligent operation box needs to communicate with the compartment layer equipment of different manufacturers, and it needs to have good interoperability
Otherwise, the application is very limited

Embodiment Construction

[0022] The technical solution of the present invention will be described in further detail below according to the accompanying drawings.

[0023] The invention discloses a switch intelligent interface unit, such as figure 1 As shown, the switch intelligent interface unit includes GOOSE and PLC modules, input modules, output modules and power modules.

[0024] The switch intelligent interface unit includes GOOSE and PLC module, input module, output module and power supply module. The GOOSE communication and PLC module, input module and output module are connected by high-speed internal bus. The ground cable is connected with contacts such as the tripping and closing positions of the circuit breaker to complete the collection of switch state quantities; The control of the circuit breaker is completed; the GOOSE and PLC modules complete the GOOSE communication initialization, GOOSE receiving, and GOOSE sending functions according to the configuration file, and realize the softwa...

Abstract

The invention discloses a switch intelligent interface unit which has the technology comprising: the switch intelligent interface unit is directly installed inside a circuit breaker and forms an organic whole together with the circuit breaker, and an outdoor installation cabinet can be omitted; a software programmable logic (PLC) way is used for replacing a great deal of hardware of a base relay and realizing a secondary circuit of the circuit breaker, so that the secondary circuit of the circuit breaker can be simplified and optimized; and IEC 61850 configuration and GOOSE communication mechanism are supported. The switch intelligent interface belongs to the control field of an electric power system, and can be used for solving the problems of process layer state quantity information acquisition and switch control of a digitized substation.

Description

technical field [0001] The invention belongs to the field of power system control, and in particular relates to a digital interface unit which can be used to solve the acquisition and control process of switch state quantities in the process layer of a digital power station. Background technique [0002] The main feature of digital substation is "intelligent primary equipment and networked secondary equipment". Considering the current level of circuit breaker technology and the transformation of old stations, it is generally used to add smart terminals to traditional switches to realize the digitization of circuit breaker signal collection and control processes. At present, the layout mode of smart terminals is mainly to install on-site in the switch yard through the outdoor cabinet. This method has the following disadvantages: [0003] 1) Although the space distance between the intelligent unit and the circuit breaker is shortened, the connection and cooperation method re...
