摘要
Abstract
There is a controversy for the -48 V DC power supply to communication devices in substations of 110 kV or above: whether "AC-DC independent power supply" or "Operating power supply + DC-DC integration power supply" should be adopted. Aiming at the issue, this article analyzes the two kinds of power supply and makes comparison between them, resulting in a conclusion that "Operating power supply + DC-DC integration power supply" is not recommended for the power supply to the system communication devices in the substations as its functional level, reliability and power source quality are worse than that of "AC-DC independent power supply".关键词
