Embodiment Construction

[0028] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0029] Such as figure 1 As shown, the dual-circuit acquisition and tripping interface device of the present invention is equipped with multiple acquisition units of the same type, including power acquisition units and non-electric power acquisition units. exist figure 1 Among them, the device is connected to three non-power collection units, which are non-power collection unit A, non-power collection unit B and non-power collection unit C; it is connected to three power protection units, which are power protection A and power protection B and power protection C. These six acquisition units are equally divided into two ways to connect to the device of the present invention. After the device logically processes the two signals of the same device, i...

Abstract

The invention relates to a dual loop collecting and tripping interface device. The dual loop collecting and tripping interface device comprises two collecting and tripping circuits arranged redundantly; each collecting and tripping circuit comprises an input module and an interface processing module connected with the input module; the interface processing module is also connected with a processing module and an export module for outputting control signals for splitting and closing the circuit breaker; the dual loop collecting and tripping interface device also comprises a GOOSE input interface module connected with the processing module; each input module comprises a plurality of interface units, and the interface processing module controls the corresponding interface unit; and the dual loop collecting and tripping interface device comprises an optical fiber interface module and a GOOSE output interface module. The dual loop collecting and tripping interface device accesses multiple identical data sources and makes logical discrimination, therefore, the device is upgraded again on the basis of enhanced reliability; the data source and protection tripping of the device are designedinto two loops with independent collecting and independent tripping, therefore, the malfunction of the project can not be caused by the damage of a single device or single loop; the reliability of the system is improved, and the normal operation of the system is ensured.

Description

technical field [0001] The invention belongs to the technical field of direct current transmission, and in particular relates to a double-loop acquisition and tripping interface device. Background technique [0002] In order to further improve the reliability of the operation of the DC transmission system, the Biotechnology Department of the headquarters has deeply analyzed the results of 137 DC forced operation failures and 3,878 hidden dangers since 2003, and analyzed and refined them one by one. Twenty-One Anti-accident Measures for Unipolar and Bipolar Forced Outages (hereinafter referred to as anti-accident measures). According to the requirements of countermeasures, the reliability of protection tripping is improved through engineering design for non-electricity tripping components and electric quantity tripping components. During the working process of the DC transmission system, it is inevitable that there will be malfunctions, which will seriously affect the stable...
