18、ers of IEEE Standards documents should be aware that these documents may be superseded at any time by the issuance of new editions or may be amended from time to time through the issuance of amendments, corrigenda, or errata.

When a document is more than ten years old and has not undergone a revision process, it is reasonable to conclude that its contents, although

36、tion This introduction is not part of IEEE Std 421.2-2014, IEEE Recommended Practice for Overvoltage and Insulation Coordination of Transmission Systems at 1000 kV AC and Above. This guide presents dynamic performance criteria, definitions, and test objectives for excitation control systems as appli
37、ed by electric utilities. It should be specifically noted that the term excitation control system refers to the entire control system including the synchronous machine and power system as well as the excitation system. The Working Group on Excitation Control System Dynamic Performance of the Excitat
38、ion Systems and Controls Subcommittee of the Energy Development and Power Generation Committee adopted many definitions and performance criteria, which are common to all control systems, and derived others specifically related to excitation control systems. In doing this, the material in IEEE Std 42
39、1.1, IEEE Standard Definitions for Excitation Systems for Synchronous Machines and the now discontinued IEEE Std 100-1988, IEEE Standard Dictionary of Electrical and Electronics Terms (ANSI) was heavily used. Efforts were made not to conflict with existing definitions and criteria, but to clarify, s
40、upplement, and more fully define them as related specifically to excitation control systems. Definitions from these standards, which are reproduced in this standard, are included in Clause 3. In preparing this guide, the working group recognized that both factory testing and field testing of excitat
41、ion control systems and some of their components are costly and often impractical. Alternator-rectifier excitation systems in which the terminals of the exciter may not be available may preclude field testing of the exciter separately. Compound source excitation systems whose power is derived from t
42、he generator currents and voltages present special difficulties. Providing a load which reasonably duplicates the generator field characteristics, so that regulation effects and proper waveforms can be adequately simulated, may not be economically justifiable. Field tests on units under normal opera
43、ting conditions are constrained to comply with the operating and security requirements of the power system, which often prohibit large excursions of the excitation control system variables. For many applications, it is necessary to devise practical test procedures for individual components and then
44、by analytical means, to verify the total excitation system performance. The need for models that accurately simulate the operation of excitation control systems during system disturbances demands effective test methods. However, the practical limitations on tests make it difficult to measure the par
45、ameters required for models. One solution is the collection of more complete data during system disturbances. Present instrumentation practices generally do not include the collection of data from enough excitation control system variables to permit the data to be used for model refinement. Improvin
46、g the quantity and quality of data collected during system disturbances may be the only practical way to obtain the data required to significantly improve the accuracy of large signal models. This revision incorporates a general introduction to the dynamic performance classification section to aid u
47、nderstanding, and the effects of excitation limiters are introduced. Clarifications have been introduced where technology advancements have changed approaches in modelling, such as the introduction of integral control terms whereby open-loop steady-state gain is considered infinite. Additional and i
48、mproved figures have been introduced and some typical parameters are shown. It is important to note that this document is part of the IEEE 421 series of guides on the various aspects of excitation control systems for synchronous generators and that the IEEE Excitation Systems and Controls Subcommitt
49、ee has also produced a tutorial on Power System Stabilization via Excitation Control which provides substantial supplemental material. Copyright 2014 IEEE. All rights reserved. viii Contents 1.
