It was subsequently revised in 1995 and reaffirmed in2002. The guide is designed for the protection of typical steam, hydraulic, and c

5、ombustion turbinegenerators (CTGs). Schemes that are judged to be good alternative practice for generator protection areincluded. New schemes that have gained acceptance and usage have been added to the guide.In this revision of IEEE Std C37.102-1995, several areas were improved. Among the most nota

6、ble are thefollowing additions: A new clause (Clause 6) on multifunction generator protection systems (MGPS) A new annex (Annex A) on sample calculations for setting of generator protection functionsNotice to usersErrataErrata, if any, for this and all other standards can be accessed at the followin

28、 protection of synchronous generators presents a review of the generallyaccepted forms of protection for the synchronous generator and its excitation system. It summarizes the useof relays and devices and serves as a guide for the selection of equipment to obtain adequate protection. Theguide is pri

29、marily concerned with protection against faults and abnormal operating conditions for largehydraulic, steam, and combustion turbine generators. Basing generator protection on machine size isdifficult because the desired protection may be determined more by the importance of the generator to thepower

30、 system than by the size of the generator.The recommendations made pertain to typical synchronous generator installations. However, sufficientbackground information relating to protection requirements, applications, and setting philosophy is given toenable the reader to evaluate the need, to select,

31、 and to apply suitable protection for most situations.The protective functions discussed in this guide may be implemented with a multifunction microprocessorbased protection system (digital system). The protection philosophy, practices, and limits are essentiallyidentical to those of the implementat

32、ion using discrete component relays. The algorithms used to performsome of the protection functions may be different, but should produce equal or better protection. However,the performance and capability may be superior using the digital systems such as improved frequencyresponse (bandwidth) and thr

33、esholds (pickup settings). Other additional features may be available fromthese digital systems that enhance the functionality.This guide does not purport to detail the protective requirements of all generators in every situation. Forexample, standby and emergency-use generators are specifically exc

34、luded. 1.1 Description of the guideClause 3 presents a brief description of typical generator design and connections, generator groundingpractices, excitation systems design, and generating station arrangements. The intent of this clause is topresent information that affects the protection arrangeme

35、nt and selection of protective relays.A discussion of auxiliary system transfer and the possible negative impacts of misoperation and faults onthese systems are beyond the scope of this guide.IEEEStd C37.102-1006 IEEE GUIDE FOR AC GENERATOR PROTECTION2Copyright 2007 IEEE. All rights reserved.The met

36、hods employed for grounding and fusing the secondary circuits of voltage transformers (VTs) andthe methods for grounding current transformer (CT) secondary circuits are not generally the same for allinstallations. CT and VT secondary circuits should be grounded in accordance with IEEE Std C57.13.3.1

37、Clause 4 briefly describes the damaging effects of faults and abnormal operating conditions and the type ofdevices and their settings commonly used to detect these conditions. A clear understanding of the effects ofabnormalities on generators will assist the reader in evaluating the need for and the

38、 means of obtainingadequate generator protection in any specific situation.Clause 5 presents a discussion of other forms of protection and factors that may be considered in thegenerator zone.Clause 6 describes multifunction generator protection systems (MGPS) and presents an application on atypical

39、generating unit and includes information on testing of MGPS. Clause 7 presents detailed diagrams that are classified according to the method by which the generator isconnected to the system. These diagrams show the combination of relays (and their control function) oftenapplied for generator and exc

40、itation system protection in accordance with good engineering practices. Thesediagrams also consider the protective devices on other equipment in or adjacent to the generating station thatare connected to trip or shut down the generator.Annex A describes sample calculations for settings of generator
