结合轨道交通机电系统的特点,提出集中设置UPS的可行性及方案。各机电系统可采用UPS部分整合或全部整合的方案,以达到节约能源,降低投资的目的。轨道交通机电系统较多,各系统对电源的性能和后备时间不尽相同,因此大多数系统采用了单独设置不间断电源或EPS的方式,具有将电源故障风险分散,各系统互不影响的优点,但也有设备重复设置,设备品牌、型号及规格多,不易维护管理,设备房占用面积大,设备管理分散等缺点。通过对各系统电源分析,针对分散设置UPS存在的问题,本着合理设置,节约能源,减少投资的目的,提出集中设置UPS的可行性和方案。
Combined with the characteristics of rail transit electromechanical system, put forward the feasibility of centralized UPS and programs. The various mechanical and electrical systems UPS can be part of the integration or integration of all the programs in order to save energy and reduce investment purposes. There are many mechatronic systems in rail transportation, and the performance and backup time of each system are different from each other. Therefore, most systems adopt a method of setting uninterruptible power supply or EPS separately and have the advantages of dispersing the risk of power failure and not affecting each system independently of each other However, there are some shortcomings such as repeated equipment setup, equipment brands, models and specifications, difficulties in maintenance and management, large equipment room occupancy, and equipment management. Through the analysis of the power supply of each system, aiming at the problems of decentralized setting up of UPS, this paper put forward the feasibility and plan of centralized setting up of UPS based on the reasonable setting, energy saving and investment reduction.
