摘要
直流系统的安全性、可靠性影响着发电厂、变电站的运行,关系着整个电网的安全生产。近几年来,电力系统中直流系统绝缘监测的研究受到人们的普遍重视,也提出了更高、更迫切的要求。在这样的背景下,对各种直流系统接地故障检测方法的进行相关比较,并提出了在有双电源供电,双回路直流系统中检测接地故障点的新方法。
The safety and reliability of the DC system influent the run of the power plant and substation, relate to the whole power system safety in production. In recent years, the study on the DC system insulation monitoring in the power system have widely received attention increasingly, and raised the much higher, more urgent requirements. The paper is based on this background, comparing the various kinds of the detecting ground fault methods for DC system, and then suggest a new method about detecting ground fault for DC system in the dual power supply, two -circuit DC system.
