Problems solved by technology

To test the accuracy of telemetry, it is necessary to build a test system consisting of a relay protection tester, a measurement and control device, and a monitoring master station. Each part of the test system operates independently, and testers need to participate in the control of the relay protection tester and the reading of the monitoring master station. Data, test result calculation, etc., consume a lot of manpower
[0003] At present, the test method for the accuracy of measurement and control telemetry is generally to artificially connect the relay protection tester to the AC acquisition loop of the measurement and control device, and then control the relay protection tester to apply AC to the measurement and control device through the client software of the relay protection tester. The telemetry data sent by the device is read through the monitoring master station connected to the measurement and control device, and the corresponding data information is manually calculated. During the whole test, each test equipment is independent of each other, and human participation is required throughout the process, and the test results are calculated. The workload is heavy, the test efficiency is low, and the existing measuring and controlling instruments can only test one-to-one each time, and do not have the ability to test multiple devices together, which seriously affects the test efficiency.

Embodiment 3

[0072] An automatic test system for telemetry accuracy of power system measurement and control devices, the other structures are the same as those in Embodiment 1 or 2, the difference is that, specifically, there are N test data feedback interfaces 402, N≥1, and N is a positive integer.

[0073] Specifically, the judging component 400 is provided with M sub-judging units 401, and the sub-judging units 401 are matched and connected with the simulation master station component 300 and the test data feedback interface 402 respectively, M≥1, and M is a positive integer.

[0074] In this embodiment, there are five test data feedback interfaces 402 and five sub-judgment units 401 respectively, which can increase the test effect of the system on the measurement and control device.

[0075] In the actual use process, the number of test data feedback interfaces and sub-judgment units can be adjusted in time, such as being set to 3, 6 or 7 at the same time, etc., and adjusted according t...
