{A71B9185-6D48-40f4-B618-485C08C4F269}
Package notes
The CIM dynamic model definitions reflect the most common IEEE or, in the case of wind models, IEC, representations of models as well as models included in some of the transient stability software widely used by utilities.
These dynamic models are intended to ensure interoperability between different vendors’ software products currently in use by electric utility energy companies, utilities, Transmission System Operators (TSOs), Regional Transmission Organizations (RTOs), and Independent System Operators (ISOs). It is important to note that each vendor is free to select its own internal implementation of these models. Differences in vendor results, as long as they are within accepted engineering practice, caused by different internal representations, are acceptable.
Unless explicitly stated otherwise, the following modelling conventions are followed:
- limited integrators are of the non-windup type;
- it shall be possible to enter a time constant of zero (where it makes sense).

Package notes
This subclause contains standard dynamic model specifications grouped into packages by standard function block (type of equipment being modelled).
In the CIM, standard dynamic models are expressed by means of a class named with the standard model name and attributes reflecting each of the parameters necessary to describe the behaviour of an instance of the standard model.Package metadata — changes

{829F67E7-F698-4aa7-95C2-13C616AB6B78}
Package notes
The excitation system model provides the field voltage (<i>Efd</i>) for a synchronous machine model. It is linked to a specific generator (synchronous machine).
The representation of all limits used by the models (not including IEEE standard models) shall comply with the representation defined in Annex E of IEEE 421.5-2005, unless specified differently in the documentation of the model.
The parameters are different for each excitation system model; the same parameter name can have different meaning in different models.Package metadata — changes

Class notes
IEEE 421.5-2016 ST4C excitation system model. This model is a variation of the Type ST3C model, with a proportional-integral (PI) regulator block replacing the lag-lead regulator characteristic that was in the ST3C model. Both potential and compound source rectifier excitation systems are modeled. The PI regulator blocks have nonwindup limits.
Reference: IEEE 421.5-2016, 8.9.Class metadata — changes
