Retrofit Installations of Adjustable Speed Drives to Conserve Energy at Industrial Facilities
MetadataShow full item record
This paper is a progress report on a study funded by the Electrical Power Research Institute (EPRI). The purpose of the study is to identify and analyze existing installations that appear to offer opportunities for energy conservation through the use of electrical adjustable speed drives in retrofit installations. The full study addresses utility installations as well as industrial applications; this paper deals only with the industrial applications. Several cases were analyzed to determine potential energy savings, reduction in operating costs, and estimated costs for equipment and installation. A sequence of the activities required for each installation under study is discussed; commercially available equipment is reviewed; and harmonic generation and related consequential effects on the electrical system are addressed.
