All rights reserved.IntroductionThis introduction is not part of IEEE Std C37.106-2003, IEEE Guide for Abnormal Frequency Protection for PowerGenerating Plants.There are two major considerations associated with operating generating stations at abnormal frequen

25、cy:1) Protection of equipment from damage that could result from operation at abnormal frequency,and2) Prevention of a cascading effect that leads to a complete plant shutdown as long as limitingconditions are not reached during abnormal frequency operation.The major components of a plant that are a

26、ffected by abnormal frequency operation are the generator andunit step-up transformer, the turbine and/or compressor, and the station auxiliaries. The following majormodications have been brought up to the previous version of the guide (IEEE Std C37.106-1987):a) Addition of a denitions clause (Claus

27、e 3).b) Reference to the IEC standards (IEC 60034-1:1999 and IEC 60034-3:1996)aand their impact on thefrequency operation of generators in particular when they are applicable.c) Addition of a word of caution in subclause 1.1 (“Scope”) about the application of any time-fre-quency characteristic suppl

28、ied in the guide.d) Addition of a word of caution in subclause 1.1 (“Scope”) about the interpretation or application ofany clause originating from the referenced international standards.e) Removal of two turbine underfrequency relay schemes that have been evaluated as obsolete andreplacement by a pr

29、otection philosophy based on the use of modern multifunction generatorpackages.f) Addition of a new clause (Clause 8) on “System Wide Issues.”g) Addition of an informative annex (Annex B) on regional criteria.ParticipantsAt the time this guide was completed, the working group had the following membe

42、ency Protection for Power Generating Plants1. Overview1.1 ScopeThis guide has been prepared to assist the protection engineer in applying relays for the protection of gener-ating plant equipment from damage caused by operation at abnormal frequencies including overexcitation.Emphasis is placed on th

43、e protection of the major generating station components at fossil steam generatingstations, nuclear stations, and on combustion turbine installations. Consideration is also given to the effect ofabnormal frequency operation on those associated station auxiliaries whose response can affect plant outp

44、ut.The guide also presents background information regarding the hazards caused by operating generationequipment at abnormal frequencies. It documents typical equipment capabilities and describes acceptableprotective schemes. Underfrequency protection can be provided by either load shedding or a disc

45、rete under-frequency protective function. If both load shedding and a discrete protective function are used, then theymust be coordinated.It should be borne in mind that much of the information concerning the operation of turbines and generatorsat off-nominal frequency, very often, do not belong to

46、the public domain and may vary from one manufac-turer to another. In view of that situation, it is recommended that any piece of data presented in the guide asctitious, example or typical should be discussed with the equipment supplier in order to obtain the relevantand detailed information for a pa

47、rticular equipment or installation.Furthermore, when specications or clauses originating from international standards are presented and dis-cussed, it is by no means meant that these specications are automatically applicable. Verication should bemade with the manufacturer about which standards the e

48、quipment has been designed to comply with.When reference is made in the text to rated frequency, it is meant as 60 Hz or 50 Hz. When examples areprovided at the specic frequency of 60 Hz, they are also applicable to 50 Hz.IEEEStd C37.106-2003 IEEE GUIDE FOR ABNORMAL FREQUENCY2Copyright 2004 IEEE. Al
