Guide for Testing and Evaluation of the Dynamic Performance of Excitation Control Systems

This guide includes criteria, definitions, and test objectives for evaluating the dynamic performance of excitation control systems as applied by electric utilities. The term excitation control system is used to distinguish the combined performance of the synchronous machine, power system, and excitation system from that of the excitation system alone. This guide provides a basis for evaluating the closed-loop performance of excitation control systems, including synchronous machines, for both large and small signal disturbances. Confirming the adequacy of mathematical models for excitation control systems for use in analytical studies of power systems, identifying objectives for tests of excitation control systems and their components, and preparing excitation system specifications and additional standards is also be addressed. Portions of this guide also serve as educational material for people who are becoming familiar with excitation control systems. This guide applies to excitation systems used on all sizes and types of synchronous machines, including those in nuclear power facilities. Large signal performance is associated with equipment specification and acceptance testing, while small signal performance is associated with stability and model studies. Matching actual disturbance data with model simulations, however, requires that both large and small signal performance criteria be considered during design, specification, and acceptance testing, and this guide provides common definitions and methods to allow comparison between different equipment responses and for comparison of actual equipment response and simulated (model) response.

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No Superseded Standards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No Inactive-Withdrawn Standards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.


No Inactive-Reserved Standards
