Georgia Hospital Chooses Cummins Power Generation
To meet the increasing electrical needs of WellStar Kennestone Hospital's 633-bed, 1.2-million-square-foot facility, hospital officials selected a Cummins Power Generation Inc. system including new generators and paralleling system to provide emergency/standby power from a 4,700-square-foot central energy plant. The new equipment was interfaced to existing transfer switch equipment.
Working with Cummins Power South LLC, and Perry, Crabb and Associates Inc., the consulting engineers on the project, the design team selected the PowerCommand® digital paralleling system from Cummins Power Generation for integration with the generators and the ability to meet performance and interoperability requirements with existing equipment. The system features field-proven generator-set-mounted PowerCommand paralleling controls, and a system master control with separate touch-screen control panels for the generators and transfer system.
The emergency requirements for the hospital campus total approximately 2,400 kW, with the system serving emergency loads in two massive bed towers, a center for women’s health and a cancer center. With three 2 MW generator sets, there is redundancy in place to provide a premium level of reliability for the healthcare facility’s critical load requirements.
While the system has yet to experience a utility outage, “it has performed flawlessly, as specified and designed” during the required acceptance tests, according to Sam Jenkins, project engineer for WellStar Health Systems. Once the generators are operating and ready for load — which takes about 10 seconds — the system transfers power smoothly to the generators. Then the system senses when the utility comes back online, and again makes a smooth, coordinated switch back to the utility power.
