摘要
简要介绍应急电源(EPS)的种类,根据实际工程项目中的负荷特点及其特殊性,全面阐述了EPS的特点、技术方案、原理、关键技术及应用结果,通过多次模拟停电测试及实际电网停电故障的检验,EPS完全按照设计方案、在规定的切换时间内正确启动,保障了项目装置的可靠运行及人身安全,并在国内煤化工领域获得了首次成功应用。
The type of Emergency Power Supply （EPS） is briefly introduced. The characteristics, technological solutions, principles, key technology and the application results are comprehensively explained based on load character and specialty of the actual construction projects. During the simulation test of power out of service and inspection of actual power failure, the EPS can start up correctly within the fixed switching time in accordance with the design scenario, which had guaranteed the reliable running of the project and personal safety, and had to be the first successful application in the field of domestic coal chemical.
