Fault indicator performance index accuracy test method, device and storage medium

Abstract

The invention discloses a method, a device and a storage medium for measuring the performance index accuracy of a fault indicator, which are used to determine the accuracy of a short-circuit fault alarm start-up error of a fault indicator. min, the upper limit of fault current max], the intermediate value of fault current mid and the exit threshold ε; the fault identification result of the test sample under the intermediate value of fault current mid; if a fault is identified, let min=min, max=mid; if If no fault is identified, set min=mid, max=max; until max-min≤ε, and take the short-circuit fault alarm start-up error under the current intermediate value mid as the short-circuit fault alarm start-up error accuracy of the fault indicator. The invention utilizes the idea of ​​the binary search method to realize the test related to the accuracy of the performance index of the sample, realizes the automation of the test of the accuracy of the performance index of the fault indicator, and makes the obtained accuracy result more objective and closer to the actual result of the sample.

Description

technical field [0001] The present application relates to fault indicator accuracy testing, and in particular, to a method, device and storage medium for fault indicator performance index accuracy testing. Background technique [0002] For the test items related to the accuracy detection requirements in the distribution line fault indicator test plan, the tester usually needs to perform multiple tests to examine the test results of the samples under different accuracy indicators, so as to gradually approach the actual accuracy of the tested samples. This test method is cumbersome to modify the test parameters, and obtaining the test accuracy results depends on the design of the test plan, which may not objectively obtain the actual accuracy of the tested sample, and is not conducive to the automation of the test process. The invention discloses a fault indicator accuracy test method, which is suitable for test items with accuracy detection requirements in a distribution line...
