【摘要】 后备电源的设计与选择是保障车站应急照明系统在电源故障或者灾害情况下发挥作用的关键环节。通过比较UPS和EPS两种静止型后备电源后认为 ,在地铁车站应急照明系统中应采用EPS型静止型后备电源。从对电网的适应能力、满足负载要求的常规输出指标、输出能力和可靠性、智能管理和通信功能等四个方面系统分析了EPS的性能指标。最后还介绍了确定EPS额定容量和蓄电池容量的方法以及系统集成时应该注意的问题更多还原

【Abstract】 Design and selection of Spare Power Supply is the essential to emergency lighting power supply system. It is found that the Emergency Power Supply (EPS) adapted to emergency lighting of the substations on the basis of comparing Uninterrupted Power Supply (UPS) with EPS, which are two types of Static Spare Power Supply. The performance index of the EPS was analyzed including the ability to adapt the power network of the city, the general output performance index meeting the load requirement, the loading capability and reliability, intelligence management and communication. Finally, the methods ascertaining the raed capacity of EPS and storage battery, and some advertent things for system integration were introduced.更多还原
