Transient Processes of Electrical Machinery
Requirements - Modeling - Simulation
The dynamic characteristics of electric drives are largely determined by the transient behavior of electrical machinery. For this reason, transient modeling and simulation of the electrical machines as part of the system are essential during drive system development (such as the design of motors and control systems).
Developers of electrical machines as well as electric drive systems; engineers who deal with the dynamics of electric drives or are responsible for putting drive systems into operation.
Basic knowledge of electrical machinery is required.
Seminar contents will be explained on computers using practical examples and include the following topics:
- Overview of transient processes for different types and applications of electrical machines
- Requirements for machine and drive design due to dynamic loads
- Mathematical models of electrical machines
- Determination of model parameters: analytical, using FEA, from test field measurements
- Numerical simulation of transient processes
- Modeling of parasitic effects: iron saturation, air gaps, current displacement, eddy currents
- Selection of the required modeling depth
- Model coupling and interaction with converters, control systems, and mechanical systems
- Overview of software tools for transient simulation of electrical machines and drives
In this seminar, participants will learn about and practice methods of transient modeling, model parameterization, and simulation of electrical machines. Following an overview of typical transient processes, modeling and simulation basics as well as tips for correct parameterization and selection of the appropriate modeling depth based on the simulation objectives will be explained. Additionally, model coupling and co-simulation with other drive components (inverters, mechanical systems) will be discussed.
Contents and practical examples include:
- Machine types: ASM, PMSM, SPSM
- Applications: motors connected to power converters, motors and generators connected to the power grid
- Transient scenarios: short circuits, grid failure, start-up, synchronization, load changes
