VFD retrofit provides 3.75-MW boost to air-cooled Wyodak Power Plant

The traditional benefit of installing ac variable-frequency drives (VFD) includes power savings at partial speed operation. In the case of forced-draft, air-cooled condenser fans at power stations and cogeneration facilities, this typically occurs during mild ambient temperatures. However, a VFD retrofit last year at the Wyodak Power Plant in Gillette, Wyo., resulted in significant process improvements at temperature extremes. In fact, of the 3.75-MW average capacity increase achieved from the VFD installation, only 25 percent is a result of power savings at partial speed operation. Considered uneconomical when the plant was built, technology advances eliminated VFD operating problems.
