Design
UPS System Replacement Project
This project consisted of replacing six 400kVA single module UPS Systems configured in an isolated redundant topology with two 2 module UPS Systems in an active data center. The number 1 criteria for this project was that the computer room must remain fully operational 100% of the time. No outages were tolerable, even during system migration and UPS power must be available at all times. The final design included: two new closed transition automatic transfer switches, two 2 module UPS Systems configured for A/B power distribution topology to the computer room, reconfigured battery room with vented lead acid battery plant and permanent battery diagnostic system, two new UPS output distribution switchboards, wrap-around maintenance bypass, new UPS room cooling system, new EPO system and additional PDU’s and panelboard distribution on the raised floor necessary for additional equipment. Each UPS System was fully commissioned onsite with a portable load bank before placing into service. This project was completed on time within the budget constraints and most important, without any interruptions of power to the computer room.
21kV Ring Bus and Electrical Distribution System Upgrade
This project was for a large custom printing facility (in excess of 500,000 ft2). The existing electrical distribution system consisted of a single utility feed that supports five customer owned substations configured in a radial distribution topology. This system was not concurrently maintainable and was full of single points of failure that could severely impact facility operations. The new electrical distribution system consists of two utility feeders that distribute power to the substations utilizing a segmented ring bus. New substation transformers and distribution switchgear were installed to mirror the existing. When this project is completed, the electrical distribution system will be fault tolerant and concurrently maintainable. A SCADA system interfaces with this system for monitoring and control. A key component of this project is that operational downtime had to be minimized in both quantity and duration. The design had to allow for the new system to be installed and commissioned without interrupting existing operations. The system is expandable to meet future growth. The design also provides for the addition of an engine generator plant to allow the facility to remain in production during utility power outages.
