摘要
UPS是提供高质量、安全可靠备用电源的重要方法之一,为了增加整个电源系统的可靠性,通过将其组成冗余系统,目前大多采用的UPS冗余连接方式为并联与串联。结合变电站应用的实际,分析比较串联冗余和并联冗余的可靠性及技术特点。为变电站选择UPS系统的冗余连接方式提供了参考。
UPS is one of important method to improve quality and reliability of power supply. UPS redundant connection was adopted to enhance reliability of power system. The paper elaborated UPS redundant connection. Then, combining practical situation, the paper compared reliability and features of series redundant with that of parallel redundant to provide reference to choose UPS connection for substations.
