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

Abstract

The invention discloses a fault indicator performance index precision test method and device, and a storage medium. The method for determining the short-circuit fault alarm starting error precision ofa fault indicator comprises the following steps: setting a fault current detection interval [a lower fault current limit value min, an upper fault current limit value max], an intermediate fault current value mid and an exit threshold epsilon; testing a fault identification result of a sample under the intermediate fault current value mid; enabling the min to be equal to the min and enabling themax to be equal to the mid under the condition of identifying a fault; enabling the min to be equal to the mid and the max to be equal to the max under the condition of not identifying a fault; and carrying out the operation till a difference between the max and the min being less than or equal to epsilon and using a short-circuit fault alarm starting error under the current intermediate value midas short-circuit fault alarm starting error precision of the fault indicator. According to the invention, the testing related to sample performance index precision is realized by utilizing the idea of a binary search method and the testing automation of the performance index precision of the fault indicator is realized, so that the obtained precision result is objective and is close to the actualresult of the sample.

Description

technical field [0001] The present application relates to fault indicator accuracy testing, in particular to a method, device and storage medium for testing the accuracy of fault indicator performance indicators. 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 distributi...
