Embodiment 1

[0032] This embodiment provides a relay protection testing system, including:

[0033] Control center, which establishes relay protection simulation models for multiple devices under test;

[0034] A plurality of relay protection testers, the plurality of relay protection testers are respectively connected to a plurality of the devices under test, and the plurality of relay protection testers are all connected to the control center by communication;

[0035] Wherein, the control center performs real-time simulation calculation according to the relay protection simulation model, generates test data and expected test results, and sends the test data to the relay protection tester;

[0036] The relay protection tester sends the test data to the device under test, and receives the feedback data from the device under test, and the relay protection tester also sends the feedback data to the control center;

[0037] The control center and a plurality of relay protection testers are ...

Embodiment 2

[0047] This embodiment provides a relay protection testing method, such as figure 1 As shown, the steps include:

[0048] Perform real-time simulation calculations based on the relay protection simulation model, generate test data and expected test results, and send the test data to the relay protection tester;

[0049] The relay protection tester sends the test data to the device under test and receives the feedback data from the device under test, and the relay protection tester also sends the feedback data to the control center;

[0050]The bookkeeping node packs the test data, expected test results and feedback data to generate blocks. The blockchain consists of the control center and multiple relay protection testers connected to the control center as nodes. The selection methods of the bookkeeping nodes include: Each node calculates the hash value of the test data and the current timestamp information respectively, and the node whose hash value is less than the preset t...

Abstract

The invention discloses a relay protection test method and system. The relay protection test system comprises a control center, which is used to establish relay protection simulation models for a plurality of to-be-tested devices; and a plurality of relay protection testers. The control center generates test data and an expected test result, and sends the test data to the relay protection testers;each relay protection tester sends the test data to to-be-tested equipment and receives feedback data of the to-be-tested equipment to form a block chain by taking the control center and the plurality of relay protection testers as nodes, and an accounting node packages the test data, an expected test result and the feedback data to generate a block. According to the invention, a plurality of to-be-tested devices can be tested at the same time, test data is generated in real time through the relay protection simulation model, and the test efficiency is high; and a test result is stored through the block chain, so that the security, traceability and tamper resistance of the data are ensured.

Description

technical field [0001] The invention relates to the field of power systems, in particular to a relay protection testing method and system. Background technique [0002] Power system relay protection devices detect faults or abnormal conditions in the power system, issue trip commands or alarm signals, and isolate and remove faulty parts. The effective and reliable operation of relay protection devices is directly related to the safety of the power grid. [0003] At present, relay protection devices generally need to manually set test data, and relay protection devices need to be tested separately, the test efficiency is low, and the safety of test results cannot be guaranteed. [0004] Therefore, there is an urgent need to design a technical solution that can overcome the above-mentioned defects to a certain extent. Contents of the invention [0005] The purpose of the present invention is to provide a relay protection testing method and system, which simultaneously tests...
