| 摘 要： | 根据三段式阻抗继电器动作边界特性的不同,分别给出了相应的动作方程,并在此基础上提出了两种测试阻抗继电器动作边界的方法跳跃法和边界法,成功地解决了因三段式阻抗继电器有公共出口而导致测试过程过于繁琐的问题。这两种方法已经应用于投入使用的变电所二次设备微机全自动在线检测软件中,取得了满意的效果。

| Abstract: | According to the different operation characteristics of the distance relay with three sections, the corresponding operation equations are given, and two methods of skipping and boundary method to test the operation margin of the distance relay are proposed. These two methods simplify the test proceess and have been used in the software to test the secondary device of substation. Satisfactory results are obtained in practical applications. |
