摘要
针对牵引变电所微机保护装置中阻抗保护测试存在的问题,对四边形自适应阻抗保护动作特性进行了分析,提出现场测试方法和校验公式,快速、准确地完成阻抗保护动作边界校验,提高工作效率,有效缩短停电时间,保障微机保护装置动作可靠性。
Concerning the test problems of micro-processor based Protective device impedance protection,This paper analysis operating characteristic of Quadrilateral adaptive impedance protection,puts forward test methods and checking formulas.Using these methods can finish the test of trip boundary quickly and accurately,improve work efficiency and Shorten the blackout time effectively,assure reliability of micro-processor based Protective device.
