Abstract:

将两端输电系统的综合阻抗保护原理推广到三端或多端输电系统,提出一种新型广域继电保护算法。针对广域保护区域不同故障时综合阻抗的定义和计算分析,区外故障时,综合阻抗反映区域内线路等效容抗,其虚部大小为千欧级,阻抗角约为-90°;区内故障时,综合阻抗反应系统阻抗,其虚部大小不大于600Ω,阻抗角在-ε~90°之间,二者有明显区别。同时,结合广域继电保护对引起差流启动时的不同情况分析,提出三步保护方案以实现输电系统故障判断,正常运行时测量信息错误或变电站直流消失等运行工况的可靠保护。IEEE10机39节点系统仿真结果表明该算法容易整定,具有选相能力,且不受分布电容电流和过渡电阻影响,与广域差动保护相比具有较高的灵敏度。
