| 摘 要： | 针对目前太原地区220 kV变电站均设置单母差保护的情况,通过计算冶峪220 kV母线故障对系统稳定性的影响,提出了适时调整继电保护动作行为,以提高枢纽变电站无母差保护时系统运行稳定性的措施,并对母差保护校验工作和系统运行的安排提出了建议。

| Abstract: | In the light of the actual state of 220 kV substation in Taiyuan installed single busbar differential propction,the paper presents some measures to improve the realy protection adjustment and enhance the stability of system operation when the load-center substation has not been installed busbar differential protection through calculating the influenece of 220 kV busbar fault in Yeyu substation to the system stability,and puts forward some suggestions to the arrangement of busbar protection inspection and system operation. |
