▶Dynamicsi
{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).
The information in the entire clause "Common Information Model Dynamics package" is reproduced from the UML with the permission of UCAIug.Package metadata — changes

Package notes
For conventional power generating units (e.g., thermal, hydro, combustion turbine), a synchronous machine model represents the electrical characteristics of the generator and the mechanical characteristics of the turbine-generator rotational inertia. Large industrial motors or groups of similar motors can be represented by individual motor models which are represented as generators with negative active power in the static (power flow) data.
The interconnection with the electrical network equations can differ among simulation tools. The tool only needs to know the synchronous machine to establish the correct interconnection. The interconnection with the motor’s equipment could also differ due to input and output signals required by standard models.Package metadata — changes

An asynchronous machine model represents a (induction) generator or motor with no external connection to the rotor windings, e.g. a squirrel-cage induction machine.
The interconnection with the electrical network equations can differ among simulation tools. The program only needs to know the terminal to which this asynchronous machine is connected in order to establish the correct interconnection. The interconnection with the motor’s equipment could also differ due to input and output signals required by standard models.
The asynchronous machine model is used to model wind generators type 1 and type 2. For these, normal practice is to include the rotor flux transients and neglect the stator flux transients.Package metadata — changes
