数字化变电站10kV母线保护方案研究

The Study of 10kV bus protection scheme on the digital substation

中压母线在发生短路故障时产生的电弧光对设备及人员造成极大的损害，为了满足继电保护快速性的要求，在一些重要的变电站中压母线配置专用的母线保护。目前数字化变电站的建设已由理论研究走向工程实践阶段，本文结合数字化变电站的建设提出了几种中压母线保护的解决方案。

When the short circuit in the MV bus, the arc win be seriously injurious to the equipments and people. In order to meet the rapidity requirement of relay protection, we set up a specialized MV bus protection in some important substations. Now the construction of digital substations has progressed from theory into engineering steadily. In this paper, combined with the digital substation construction, it is put forward several solutious about the MV bus protection.
