Problems solved by technology

Therefore, at present, the inspection of relay protection devices is generally carried out manually, that is, the inspectors go to the relay protection site to inspect the corresponding functions of the relay protection device in sequence according to the purpose of the inspection function, but the speed of manual inspection is relatively slow. , making the test less efficient

Embodiment 1

[0048] see figure 1 It shows a schematic structural diagram of Embodiment 1 of an inspection system for a relay protection device provided by the present application, and the system includes: an acquirer 101 and an analyzer 102;

[0049] Wherein, the acquirer 101 is configured to receive a request for inspecting the purpose inspection function of the relay protection device, analyze the request, and obtain parameter information and output signals of the relay protection device corresponding to the request;

[0050] When inspecting a relay protection device, it is first necessary to make an inspection request for the function that needs to be inspected, that is, the purpose inspection function. According to the signal corresponding to the purpose inspection function, the acquirer 101 acquires the parameter information and output signal of the relay protection device corresponding to the request, and according to the parameter information and output signal, the relay protection ...

Embodiment 2

[0061] see figure 2 It shows a schematic structural diagram of Embodiment 2 of an inspection system for a relay protection device provided by the present application. figure 1 In the shown structure, it also includes: analysis model builder 103;

[0062] Wherein, the analysis model builder 103 is used to generate an analysis model according to preset inspection regulations / standards and work instructions.

[0063] Analysis models include analysis procedures and standard formats for analysis results.

[0064] The analysis model builder 103 is a part that provides the analysis model for the analyzer 102 .

[0065] When inspecting relay protection devices, it needs to be carried out based on the inspection regulations / standards and work instructions. The inspection items and inspection requirements need to be based on the inspection regulations / standards. The inspection results should be filled in the report form in the operation instructions. . Therefore, the analysis proce...

Embodiment 3

[0076] see Figure 4 It shows a schematic structural diagram of Embodiment 3 of an inspection system for a relay protection device provided by the present application. figure 2 In the shown structure, it also includes: a memory 104;

[0077] The memory 104 is used to store parameter information, output signals and analysis results of the relay protection device.

[0078] The memory 104 stores the data information of each test, such as the parameter information and output signal acquired by the acquirer 101, the analysis result of the analyzer 102, and the time when the test is carried out, etc., and the data information has a unique ID (IDentity, serial number) identification, used as a historical inspection report for query, statistics, analysis, etc.

[0079] In actual implementation, the memory 104 is based on the B / S (Browser / Server, browser / server) mode, using SQL Server2000 or Oracle database, can realize the process management of the entire inspection process, so tha...

Abstract

The invention provides a testing system and testing method for a relay protection device. The testing method comprises that an obtaining device receives the requirements for testing a purpose testing function of the relay protection device, analyzes the requirements, and obtains parameter information and output signals of the relay protection device corresponding to the requirements; an analyzer analyzes the parameter information and the output signals according to a preset analytical model, and generates analysis results; and the analytical model comprises a standard format of analysis processes and analysis results. The relay protection device can be corrected according to the analysis results so as to protect sensitivity of the relay protection device. By adopting the testing system and testing method for the relay protection device, the relay protection device can be automatically tested, and efficiency is high.

Description

technical field [0001] The application belongs to the field of power systems, and in particular relates to an inspection system and an inspection method for a relay protection device. Background technique [0002] A relay protection device is a device that combines one or more protection elements (such as relays) and logic elements as required to complete a specific protection function in the current system. [0003] When the power components in the power system (such as generators, lines, etc.) or the power system itself fail to endanger the safe operation of the power system, the relay protection device can send a warning signal to the operator on duty in time, or directly send a warning signal to the controlled circuit breaker. The device issues a trip command to terminate these event developments. It can be seen that in the power system, the role of relay protection devices is very important. [0004] In order to ensure that the various functions of the relay protectio...
