UNINTERRUPTIBLE POWER SYSTEM MODULE ANALYSIS.
Abstract
A module analysis was conducted to determine the optimum rating of module which, together with identical modules, would best satisfy the contractual requirements for an uninterruptible ac power (u-p) supply system for use in Federal Aviation Administration (FAA) Air Route Traffic Control Centers. In determining the optimum module output capacity, due consideration was given to incurring the lowest initial and recurring cost over a 10-year period, the possibility of future u-p supply installations at 18 other centers in addition to the present Islip, N.Y., installation under contract with regard to (1) their initial critical load magnitudes (98-381 kva); (2) ultimate loads of 500 kva; (3) ultimate loads of a presently indeterminable kva; and (4) the interchangeability of modules between Air Route Traffic Control Centers. Also considered in this analysis was a quantitative economic and operational determination of various module output capacities and module circuit configurations as they relate to critical loads of both a steady state and transient nature, electrical performance, efficiency, redundancy, maintainability, space and future expansion requirements, and reliability requirements. Six basic circuit configurations were investigated at power levels ranging from 50 kva modules to 250 kva modules. (Author)
