Revision Standard – Inactive – Withdrawn. Project scope: Original Scope: The guide is intended to cover the application of drive systems designed for connection to power plant electrical auxiliaries systems (normally rated between 2300V and 13,800V). It includes drives system terminilogy, drive classifications, typical applications and their unique charasteristics and design considerations, protection, packaging – interfaces and interactions. Revised Scope: 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. Project purpose: Original Purpose: To provide guidelines on drive selection and applications for electric generating station applications. Revised Purpose: The purpose of this Guide is to provide a fundamental understanding of the operation, selection, and application of ASDs for use in electric power generation plant motor-driven systems connected to electric service rated at 2400 volts to 13,800 volts.
