| 摘 要： | 基于稳定控制装置安装处的测量阻抗值在线路无故障跳闸时和潮流转移时具有明显差异的机理,形成了基于本地电气量的无故障跳闸新判据,利用HYPERSIM实时数字仿真系统和物理动模系统通过UFV-200C型稳定控制装置对该判据的正确性、可靠性和有效性进行了验证。实验结果表明:基于新判据的稳控装置能可靠区分线路对侧跳闸和潮流转移过程。

| Abstract: | Based on the mechanism of the measured impedance having distinct different values in non-fault line tripping out and power swing, this paper describes the new criterion of identifying non-fault line tripping based on local impedance measurements. The use of UFV-200C Stability Control Device validates the effectiveness and reliability of the new method by HYPERSIM real-time digital simulation and physical model test. Results of the tests show that the new method can distinguish between non-fault line tripping and system power flow transfer. |
