摘　　要：为保证保护装置的可靠性、选择性、灵敏性和速动性,需要对其进行定期校验。目前大部分校验工作及结果判断都由人工完成,保护装置的性能高低、功能正确与否与校验人员评判标准及校验误差息息相关。为减少人为因素的参与,对继电保护的自动校验装置及自动校验系统两种校验方法进行研究,设计无干扰、无影响的校验方式,以期进一步提升继电保护装置校验的智能、高效水平。In order to ensure the reliability,selectivity,sensitivity and rapidity of the protection device,it is necessary to calibrate the protection device regularly.At present,most of the calibration work and result judgment are done manually.The performance and function of the protection device are closely related to the evaluation standard and calibration error of the calibration personnel.In order to reduce the participation of human factors,the two calibration methods of automatic calibration device and automatic calibration system of relay protection are studied.In order to further improve the intelligent and efficient level of relay protection device calibration,a non-interference and non-impact calibration method is designed.
