Adjustable Speed Drive (ASD) Feasibility Analysis
Abstract
Approximately half the electrical load at most Army facilities is devoted to electrical motors that operate much of the time below their rated load or with mechanical dampers to reduce their effect. When planning either retrofit or new installations, designers and engineers must frequently determine the most economical types of drives and motors to specify for a variety of circumstances. The U.S. Army Construction Engineering Research Laboratories (USACERL) is developing ASDAPLUS, a personal computer PC-based software package, to automate the analysis required to determine the most cost-effective combination of drive and motor in each instance. ASDAPLUS computes and compares the life-cycle costs of installing a motor with or without an adjustable speed drive (ASD). ASDAPLUS also computes and compares the life-cycle costs of using standard efficiency motors versus high efficiency motors. ASDAPLUS is designed for use by Directorate of Engineering and Housing (DEH) engineers and others who must make decisions based on such considerations. This report describes the technical derivation of ASDAPLUS, the current status of the development effort, and the work yet to be done.
