Abstract
Abstract
At present, the conventional localized equipment calibration technology mainly adopts the manual way to check the equipment parameters, which leads to low calibration accuracy due to the lack of analysis of the calibration error sources. In this regard, the localized equipment calibration technology for substation relay protection considering electromagnetic interference is proposed. The calibration error value is calculated by simulating a high-precision localized equipment unit, designing the pre-circuit for fast voltage and current sampling, and analyzing the calibration error source. The experimental results show that the proposed calibration technique can effectively reduce the delay characteristic error value of the equipment and has a high calibration accuracy. The delay characteristic error of the average calibration is lower than 23%.
