配置细节
为了突出强调在选择一款无冗余科士达UPS与一款N + 1 UPS时的权衡取舍，我们已经分析了三种具体的配置。在这三种情况下，我们选择了1MW的额定容量。
1、基准的1N配置：一款单一的1000 kW UPS，没有冗余(由四个“内部”250千瓦模块组成);属于基本情况
2、内部“模块化”冗余N + 1配置：一款模块化的1000 kW UPS，包括五个“内部的”250 kW模块(其中四个用于容量和一个用于冗余)
3、并联冗余N + 1配置：三款500 kW UPS “框架”配置作为并联冗余(两个用于容量和一个用于冗余)
基本的1N配置
借助一款1N 科士达UPS设计，任何组件的故障都需要转移负载到科士达UPS旁路或环绕旁路。简单的例子是一款单一的科士达UPS额定支撑整个负载。某些科士达UPS被设计成模块化和规模化，而某些则是具备固定的容量。我们所分析的1N UPS是一种模块化设计，由在一个单一的框架内的四个250千瓦的模块组成，以达到1000千瓦的额定容量。1N也可以由多个单元并联在一起以共同实现所需的容量来实现。下图2展示了我们所分析的1N UPS。
Assist in a 1N Corstal UPS design, any component failure needs to transfer load to or around the Corstal UPS bypass. The simplest example is a single Costa UPS rating that supports the entire load. Some Corstal UPS are designed to be modular and large-scale, while others have fixed capacity. The 1N UPS we analyzed is a modular design consisting of four 250 kW modules in a single framework to achieve the rated capacity of 1000 kW. 1N can also be realized by parallel connection of multiple units to achieve the required capacity. Figure 2 below shows the 1N UPS we analyzed.
