摘要
通过对电流采样值差动保护原理和判据形式的研究,定量分析了采样值电流差动保护抗TA饱和的作用,体现了采样值差动保护动作的可靠性将高于有效值差动保护。
Based on the research on the principle and the criterion form of the current differential protection of sample values,the quantificational Analyzing the anti-TA saturation reflects of the current differential protection of sampling values shows that the sample values differential protection to be higher than virtual values differential protection for the reliability of activity protection.
