Active Standard

IEEE 421.1-2021

IEEE Standard Definitions for Excitation Systems for Synchronous Machines

Defined in this standard are elements and commonly used components in excitation systems. Also contained are definitions for excitation systems applied to synchronous machines. An included annex contains one-line block diagrams of some typical excitation systems. These are presented to illustrate the defined terminology referenced in this standard and clarify the understanding of the excitation control system.

Other Activities From This Working Group

Current projects that have been authorized by the IEEE SA Standards Board to develop a standard.


No Active Projects

Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.


No Active Standards

These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.


No Superseded Standards

These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.


No Inactive-Withdrawn Standards

These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.


421.1-2007
IEEE Standard Definitions for Excitation Systems for Synchronous Machines

This standard defines elements and commonly used components in excitation control systems and contains definitions for excitation systems as applied to synchronous machines. These definitions should be useful in the following areas: -- Writing excitation systems specifications -- Evaluating excitation system performance -- Specifying methods for excitation system tests -- Preparing related excitation system standards -- Serving as an educational means for those becoming acquainted with excitation systems -- Modeling excitation systems
