Foreword
(This
Foreword is not a part of ANSI/IEEE Std 421.1-1986, IEEE Standard
DeÞnitions for Excitation Systems for Synchronous Machines.)
This
standard deÞnes elements and commonly used components in excitation
systems and contains deÞnitions for excitation systems applied to
synchronous machines, for general requirements of a synchronous machine
refer to ANSI C50.10-1977.
A synchronous machine
excitation control system operating under automatic control is a
feedback control system.Thus, the working group Terminology of the
Excitation Subcommittee of the Power Generation Committee adopted
deÞnitions that had common basis to excitation systems. Efforts were
made not to conßict terms found in ANSI/IEEE Std 100-1984 , IEEE
Standard Dictionary of Electrical and Electronics Terms, but to clarify
or more fully deÞne terms as related speciÞcally to excitation of
synchronous machines. The task of the working group can be divided into
two areas
