分析变电站直流母线电压异常原因及处理步骤

Analysis on the reasons and treatment steps of DC bus voltage abnormity in Substation

直流系统作为变电站最基本的系统控制以及保护部分,为各种装置(如测控、自动装置)提供工作电源。确保直流系统的正常运作是至关重要的问题。由于计算机网络和通信技术的更新换代,变电站直流系统也对于自动化及系统本身的稳定和可靠运行提出要求。

DC system as the most basic system control and protection of the substation,for a variety of devices（such as measurement and control,automatic device）to provide a working power supply.To ensure the normal operation of the DC system is an important issue.Due to the upgrading of computer network and communication technology,substation DC system is also required for automation and stability and reliable operation of the system itself.
