          Revision Standard - Superseded.<br />\n
          Revision of IEEE Std 1110-1991. Reaffirmed September 2007. Categorizes three direct-axis and four quadrature-axis models, along with the basic transient reactance model. Discusses some of the assumptions made in using various models and presents the fundamental equations and concepts involved in generator/system interfacing. Covers, generally, the various attributes of power system stability, recognizing two basic approaches. The first is categorized under large disturbance nonlinear analysis; the second approach considers small disturbances, where the corresponding dynamic equations are linearized. Applications of a range of generator models are discussed and treated. The manner in which generator saturation is treated in stability studies, both in the initialization process as well as during large or small disturbance stability analysis procedures is addressed. Saturation functions that are derived, whether from test data or by the methods, of finite elements are developed. Different saturation algorithms for calculating values of excitation and internal power angle depending upon generator terminal conditions are compared. The question of parameter determination is covered. Two approaches in accounting for generator field and excitation system base quantities are identified. Conversion factors are given for transferring field parameters from one base to another for correct generator/excitation system interface modeling, Suggestions for modeling of negative field currents and other field circuit discontinuities are included.<br />\n
          \t\t\t\t<br />\n
          Review all 7 chapters of the existing Standard and determine which chapters, if any, need updating or significant additions. Correct, where applicable, existing typographical errors. Suggest, when necessary, new figures, illustrations, or references.<br />\n
          The modeling of synchronous machines for stability studies and analyses is subject to continuing review and possible improvements. Both parameter identification for dynamic analysis and accounting for generator saturation must be included. Emphasis will be placed on discussing various aspects of Synchronous Generator/Power System interactions.

          Revision Standard - Superseded.<br />\n
          Revision of IEEE Std 1110-1991. Reaffirmed September 2007. Categorizes three direct-axis and four quadrature-axis models, along with the basic transient reactance model. Discusses some of the assumptions made in using various models and presents the fundamental equations and concepts involved in generator/system interfacing. Covers, generally, the various attributes of power system stability, recognizing two basic approaches. The first is categorized under large disturbance nonlinear analysis; the second approach considers small disturbances, where the corresponding dynamic equations are linearized. Applications of a range of generator models are discussed and treated. The manner in which generator saturation is treated in stability studies, both in the initialization process as well as during large or small disturbance stability analysis procedures is addressed. Saturation functions that are derived, whether from test data or by the methods, of finite elements are developed. Different saturation algorithms for calculating values of excitation and internal power angle depending upon generator terminal conditions are compared. The question of parameter determination is covered. Two approaches in accounting for generator field and excitation system base quantities are identified. Conversion factors are given for transferring field parameters from one base to another for correct generator/excitation system interface modeling, Suggestions for modeling of negative field currents and other field circuit discontinuities are included.<br />\n

          Superseded by 1110-2002. Three direct-axis and four quadrature-axis models are categorized, along with the basic transient reactance model. Some of the assumptions made in using various models, including the basic model, are discussed, and the fundamental equations and concepts involved in generator/system interfacing are presented. The various attributes of power system stability are covered in a general way, with two basic approaches being recognized. The first is categorized under large-disturbance nonlinear analysis. The second approach considers small disturbances, where the corresponding dynamic equations are linearized. Applications of a range of generator models are discussed and treated. The manner in which generator saturation is treated in stability studies, both in the initialization process, as well as during large or small disturbance stability analysis procedures is addressed. Saturation functions that are derived either from test data or by the methods of finite elements are developed. Different saturation algorithms for calculating values of excitation and internal power angle, depending upon generator terminal conditions, are compared. The question of parameter determination is thoroughly covered. Two approaches in accounting for generator field and excitation system base quantities are identified. Conversion factors are given for transferring field parameters from one base to another for correct generator/excitation system interface modeling. Suggestions for modeling of negative field currents and other field circuit discontinuities are included.<br />\n

          This guide contains instructions for modeling synchronous machines in direct- and quadrature-axis equivalent circuits, along with the basic transient and subtransient reactance/time-constants model in view of stability studies. It discusses assumptions made in using various models and presents the fundamental equations and concepts involved in generator/system interfacing. The manner in which generator saturation is treated in network studies, both in the initialization process as well as during large or small disturbance stability analysis procedures is addressed. Approaches for improving the accuracy of field and excitation system quantities are identified and conversion factors are given for transferring field parameters from one base to another for correct generator/excitation system interface modeling. Parameter determination and translation from equivalent-circuits to operational impedances or vice-versa is covered. Data analysis methods for obtaining these parameters using measurements from field tests or finite-element computations are explained and illustrated with a wide range of generator and test data. However, this guide refers to applicable standards (such as IEEE Std 115) or contract specification for scheduling such tests. Also, this guide does not attempt to recommend specific procedures for machine representation in non-standard or atypical cases such as generator tripping and overspeed operation or models for harmonics or unbalanced operation.<br />\n
          The modeling of synchronous machines for stability studies and analyses is subject to continuing review and possible improvements. The guide addresses both parameter identification for static and dynamic stability analyses while accounting for generator saturation. Emphasis is placed on discussing various aspects of synchronous generator/power system interactions in steady and dynamic operation modes

          Revision Standard - Superseded.<br />\n
          Revision of IEEE Std 1110-1991. Reaffirmed September 2007. Categorizes three direct-axis and four quadrature-axis models, along with the basic transient reactance model. Discusses some of the assumptions made in using various models and presents the fundamental equations and concepts involved in generator/system interfacing. Covers, generally, the various attributes of power system stability, recognizing two basic approaches. The first is categorized under large disturbance nonlinear analysis; the second approach considers small disturbances, where the corresponding dynamic equations are linearized. Applications of a range of generator models are discussed and treated. The manner in which generator saturation is treated in stability studies, both in the initialization process as well as during large or small disturbance stability analysis procedures is addressed. Saturation functions that are derived, whether from test data or by the methods, of finite elements are developed. Different saturation algorithms for calculating values of excitation and internal power angle depending upon generator terminal conditions are compared. The question of parameter determination is covered. Two approaches in accounting for generator field and excitation system base quantities are identified. Conversion factors are given for transferring field parameters from one base to another for correct generator/excitation system interface modeling, Suggestions for modeling of negative field currents and other field circuit discontinuities are included.<br />\n
          \t\t\t\t<br />\n
          Review all 7 chapters of the existing Standard and determine which chapters, if any, need updating or significant additions. Correct, where applicable, existing typographical errors. Suggest, when necessary, new figures, illustrations, or references.<br />\n
          The modeling of synchronous machines for stability studies and analyses is subject to continuing review and possible improvements. Both parameter identification for dynamic analysis and accounting for generator saturation must be included. Emphasis will be placed on discussing various aspects of Synchronous Generator/Power System interactions.

          New IEEE Standard - Superseded.<br />\n
          Superseded by 1110-2002. Three direct-axis and four quadrature-axis models are categorized, along with the basic transient reactance model. Some of the assumptions made in using various models, including the basic model, are discussed, and the fundamental equations and concepts involved in generator/system interfacing are presented. The various attributes of power system stability are covered in a general way, with two basic approaches being recognized. The first is categorized under large-disturbance nonlinear analysis. The second approach considers small disturbances, where the corresponding dynamic equations are linearized. Applications of a range of generator models are discussed and treated. The manner in which generator saturation is treated in stability studies, both in the initialization process, as well as during large or small disturbance stability analysis procedures is addressed. Saturation functions that are derived either from test data or by the methods of finite elements are developed. Different saturation algorithms for calculating values of excitation and internal power angle, depending upon generator terminal conditions, are compared. The question of parameter determination is thoroughly covered. Two approaches in accounting for generator field and excitation system base quantities are identified. Conversion factors are given for transferring field parameters from one base to another for correct generator/excitation system interface modeling. Suggestions for modeling of negative field currents and other field circuit discontinuities are included.<br />\n

          This guide contains instructions for conducting the more generally applicable and accepted tests to determine the performance characteristics of synchronous machines. Although the tests described are applicable in general to synchronous generators, synchronous motors (larger than fractional horsepower), synchronous condensers, and synchronous frequency changers, the descriptions make reference primarily to synchronous generators and synchronous motors. The tests described may be applied to motors and generators, as needed, and no attempt is made to partition this guide into clauses applying to motors and clauses applying to generators. It is not intended that this guide shall cover all possible tests, or tests of a research nature, but only those more general methods which may be used to obtain performance data. The schedule of factory and field tests which may be required on new equipment is normally specified by applicable standards or by contract specifications. This guide should not be interpreted as requiring the making of any specific test in a given transaction or implying a guarantee to meet specific performance indices or operating conditions. The term specified conditions for tests as used in this guide will be considered as rated conditions unless otherwise agreed upon. Rated conditions apply usually to the following quantities listed on the machine nameplate. These include MVA, terminal voltage (or kilovolts), armature current, and power factor.

Although the tests described are applicable in general to synchronous generators, synchronous motors (larger than fractional horsepower), synchronous condensers, and synchronous frequency changers, the descriptions make reference primarily to synchronous generators and synchronous motors. The tests described may be applied to motors and generators, as needed, and no attempt is made to partition this guide into clauses applying to motors and clauses applying to generators. It is not intended that this guide shall cover all possible tests, or tests of a research nature, but only those more general methods which may be used to obtain performance data. The schedule of factory and field tests which may be required on new equipment is normally specified by applicable standards or by contract specifications. This guide should not be interpreted as requiring the making of any specific test in a given transaction or implying a guarantee to meet specific performance indices or operating conditions. The term specified conditions for tests as used in this guide will be considered as rated conditions unless otherwise agreed upon. Rated conditions apply usually to the following quantities listed on the machine nameplate. These include MVA, terminal voltage (or kilovolts), armature current, and power factor.

          New IEEE Standard - Superseded.<br />\n
          Superseded by 1110-2002. Three direct-axis and four quadrature-axis models are categorized, along with the basic transient reactance model. Some of the assumptions made in using various models, including the basic model, are discussed, and the fundamental equations and concepts involved in generator/system interfacing are presented. The various attributes of power system stability are covered in a general way, with two basic approaches being recognized. The first is categorized under large-disturbance nonlinear analysis. The second approach considers small disturbances, where the corresponding dynamic equations are linearized. Applications of a range of generator models are discussed and treated. The manner in which generator saturation is treated in stability studies, both in the initialization process, as well as during large or small disturbance stability analysis procedures is addressed. Saturation functions that are derived either from test data or by the methods of finite elements are developed. Different saturation algorithms for calculating values of excitation and internal power angle, depending upon generator terminal conditions, are compared. The question of parameter determination is thoroughly covered. Two approaches in accounting for generator field and excitation system base quantities are identified. Conversion factors are given for transferring field parameters from one base to another for correct generator/excitation system interface modeling. Suggestions for modeling of negative field currents and other field circuit discontinuities are included.<br />\n

          New IEEE Standard - Superseded.<br />\n
          Superseded by 1110-2002. Three direct-axis and four quadrature-axis models are categorized, along with the basic transient reactance model. Some of the assumptions made in using various models, including the basic model, are discussed, and the fundamental equations and concepts involved in generator/system interfacing are presented. The various attributes of power system stability are covered in a general way, with two basic approaches being recognized. The first is categorized under large-disturbance nonlinear analysis. The second approach considers small disturbances, where the corresponding dynamic equations are linearized. Applications of a range of generator models are discussed and treated. The manner in which generator saturation is treated in stability studies, both in the initialization process, as well as during large or small disturbance stability analysis procedures is addressed. Saturation functions that are derived either from test data or by the methods of finite elements are developed. Different saturation algorithms for calculating values of excitation and internal power angle, depending upon generator terminal conditions, are compared. The question of parameter determination is thoroughly covered. Two approaches in accounting for generator field and excitation system base quantities are identified. Conversion factors are given for transferring field parameters from one base to another for correct generator/excitation system interface modeling. Suggestions for modeling of negative field currents and other field circuit discontinuities are included.<br />\n
