IEEE 958-2003

This guide applies to DC link type, AC adjustable speed drives (ASDs) as illustrated in Figure 1-1 and does not address other drive systems such as cycloconverters. The guide is intended to cover the application of drive systems for use in electric power generation stations designed for connection to electric service rated between 2400 volts and 13,800 volts. The guide includes ASD terminology, theory of operation, and a discussion of the factors that can influence equipment selection. It also defines drive system classifications and addresses typical applications. Drive system design considerations, and the interactions between the ASD and the supply system and the driven load are also discussed. Finally, guidance on ASD specifications and installation are provided.
