Version 1.6
Electrification Library 1.6 is part of Modelon’s 2021.2 release. New versions of Modelon libraries are sold and distributed directly from Modelon, as well as approved resellers.
New Features
Tutorials
- New Getting started tutorials, covering basic features and common pitfalls.
Three-phase AC machines and inverters
- Electro-magnetic models of the most common three-phase AC machines.
- Power electronic DC/AC Inverters (switched and averaged implementations).
- A set of experiments for AC machines that are useful for verification and validation.
- New system example: ACMachineInverter
- Examples of different fidelities of machines and inverters.
Batteries
- An example of SoC balancing between cells in a battery pack.
- Stochastic initialization of SoC for individual cells in battery packs (example experiment).
- Example battery with parameter variations defined using the new stochastic parameters feature in Modelon Base Library.
Machines
- Position control mode is now part of the MultiMode machine controller (example experiment).
- Added initialization of machine speed and angle (Initialization tab). This can also be used in the machine interface in experiment templates.
- Introduced steady state initialization for the machine controller (speed and voltage.
- Improved parametrization of rotor inertia for machines using a gear box.
- It is now possible to visualize the reference frame of the Rotational3D flange in Multibody3D machines like other Rotational3D components using the visualize_reference parameter.
Thermal
- The fixed_temperature parameter is now found at top level in components like batteries and machines. This allows defining experiment templates that define if thermal dynamics should be enabled.
- Added temperature limit monitors to thermal domains of all components.
- Vectorized thermal interfaces for converters and machines (enabling more thermal discretization).
- Diagram representation of heat losses in components.
Control
- External controller input signals now need to be explicitly enabled. This means e.g. that the external reference torque of machines are disabled by default.
- Added scaling factor (k_pMax) to component limit controllers. This is a simpler alternative to using a centralized allocation controller.
- Additional control bus signals for machines and batteries.
Other
- More information about power flow and temperatures in summary records.
