UPS Power System Design Parameters

This application note is intended to be a source of guidance and to help reduce confusion pertaining to the design, configuration, selection, sizing, and installation of Uninterruptible Power Supply (UPS) systems. This document is a useful information source for electrical consultants, electrical engineers, facility managers, and design and build contractors.

In the recent past, many design engineers have tried to create the perfect UPS solution for supporting critical loads. However, these designs have generally overlooked coverage for changing load profiles (e.g. leading power factor), sleep mode, and advanced scalability solutions. Such solutions and/or options can assist in gaining higher system efficiency, without exposing the critical load to disruptions from the utility.

This paper presents information related to various generic types of current UPS units, complete with their merits and demerits. It covers different topologies and various system solutions for clients. Auxiliary items, such as the battery bank, diesel generator set, and switchgear are included in the document since they also form an integral part of a UPS system.

To aid in the reduction of the carbon footprint, the paper has indicated achievable operational efficiency figures for different solutions.

A typical generic UPS Specification has been included as an Appendix to this paper to support electrical engineering professionals.
