【摘要】 基于综合阻抗的纵联线路保护原理,具有不需要补偿电容电流、受电抗器影响小等优势,本文论述了该原理在不同运行情况,包括转换性和发展性故障、振荡、非全相运行等情况下的性能,理论分析和动模数据仿真结果表明,基于综合阻抗的纵联保护原理在上述各种情况下都可以正确工作。更多还原

【Abstract】 The line pilot protection principle based on the integrated impedance needn’t compensating the line capacitive current,can work under the condition with or without shunt reactor.This paper analyze the performance of the new principle under the condition sof cross country fault,swing and only two phases operating,the analysis result shows that the new criterion can work correctly under these conditions,and the conclusion is verified with the physical model simulation result.更多还原
