| 摘 要： | 为解决特高压长线路上的电流差动保护易受分布电容电流影响的问题,提出了一种基于Marti模型的电流差动保护原理和判据,与基于贝瑞隆模型的差动保护相比,该原理考虑了线路参数的频变特性,使计算结果更加精确.在中国第1条交流特高压示范线路上的仿真结果表明,基于该原理差动保护的可靠性和灵敏度均有明显提高.

| Abstract: | To solve the vulnerability of current differential relay protection to the negative impact of the distributed capacitive current in the long UHV transmission line,a principle of and a criterion for current differential relay protection based on the Marti model are proposed.Different from the Bergeron model differential protection,the frequency-dependent characteristic of line parameters is taken into account in this principle so that the calculating result is more accurate.The simulated results concerning t... |
