Overview and objectives1.1 IntroductionThe basic techniques for studying the stability of interconnections of syn

28、chronous generators stem from thelate nineteenth century and the early years of last century. The key concept of transforming stator variablesinto quantities rotating in synchronism with the rotor was developed by Blondel B1,1Park (B62, B63),and others and remains the basis for synchronous machine a

29、nalysis to this day.To some extent, the techniques developed in those early years remained relatively untouched until the lastthree or four decades of the twentieth century. Although it was in theory possible to develop relativelycomplex generator models prior to this time, limited computational cap

30、ability meant that such models wereimpractical for use in large-scale stability studies. However, with the advent of the digital computer, thepicture changed significantly and computational capability continues to grow at a rapid rate. In addition, thegrowing complexity of electric power systems com

31、bined with the advent of more sophisticated generatorand system controls, such as high-speed, solid-state excitation systems, greatly increased the demands onstability programs. In response, the latter part of the twentieth century saw an increased interest in synchronous generatormodeling. This int

32、erest took many forms. For example, initial investigations attempted to correlate theperformance of synchronous machine models with the measured performance of specific machinesfollowing transient disturbances on a power system (Chorlton and Shackshaft B6, Dandeno et al. B12).Other investigators dev

33、eloped alternate techniques for determining machine parameters (Manchur et al.B57). The objective of this and related work, which continues to this day, is to improve the existingcapability to analyze and predict the dynamic behavior of electric power systems. This work becomesincreasingly important

34、 with the ever-increasing demands being placed on power systems as they continue togrow in size and complexity and as deregulation significantly modifies the way these systems are operatedand controlled. The objective of this guide is to summarize available practices in synchronous machine models us

35、ed inpower system stability studies. As will be discussed, computational capability has increased to the point that1The numbers in brackets correspond to those of the bibliography in Annex A.IEEEStd 1110-2002 IEEE GUIDE FOR SYNCHRONOUS GENERATOR MODELING PRACTICES2 Copyright 2003 IEEE. All rights re

36、served.it is possible to model generators (along with their excitation systems and other controls) with a significantlevel of detail, subject to the availability of the appropriate data from which to form the model. 1.2 Specialized problems in stability not discussed in this guideThis guide does not

37、 attempt to recommend specific procedures for machine representation in non-standardor atypical cases such as generator tripping and overspeed operation or models for harmonics or unbalancedoperation. Similarly, modeling suggestions for subsynchronous resonance (SSR) studies are documented inDandeno

38、 and Iravani B9 and IEEE B35. Recent investigations have shown that models developed fromsmall-signal analyses, based on standstill-frequency-response data, are also adequate for SSR investigations.This applies to situations where third-order models have been found to be necessary to cover the frequ

39、encyspectrum from 15 Hz to 50 Hz (IEEE B35).1.3 Overview of the guideClause 3 discusses the various categories of stability studies which are commonly performed during powersystem studies and the corresponding synchronous generator modeling requirements. Clause 4 thenreviews some of the basic princi

40、ples of synchronous generator modeling and discusses the range of modelswhich can be used in the study of synchronous generator dynamic behavior as is summarized in Table 1 ofClause 4. This clause emphasizes the point that a model is uniquely determined only when both itsstructure (e.g., the number

41、of assumed conducting paths in the rotor) and its parameters (as obtained fromtest data or analytical techniques) are specified. Clause 5 next presents guidelines as to how the variousmodels discussed in Clause 4 can be applied to the various types of stability studies which are discussed inClause 3

42、.Clause 6 then discusses the effects of saturation on the performance of synchronous machines and varioustechniques which have been developed for incorporating these effects in synchronous generator models.Included in Annex D is the development of direct- and quadrature-axis saturation functions. Be

43、causesaturation is an inherently nonlinear phenomenon while the commonly-used generator models are linear, thetechniques used for incorporating saturation effects into generator models are somewhat ad hoc. This is anarea in which further investigation is clearly required. Finally, Clause 7 discusses

44、 the techniques which have been developed for obtaining parameters for synchro-nous generator models. Such parameters are found either by test, as described in IEEE Std 115-1995, orfrom calculations by manufacturers.2The issue of the translation of parameters from the inductances andresistances of d

45、- and q-axis models to transient and estrangement reactances and time constants or to transferfunctions form is also discussed. 2.
