Simscape Power Systems Power Consumption

Power Consumption

Simscape Power Systems enables you to model the loads in your system at the desired level of fidelity. In addition to generic components, it provides a library of electric drives. It combines the key components (machines, power converters, and controllers) into a single block with an interface that helps you modify key parameters and add or neglect switching effects.

Power Converters

Simscape Power Systems includes power converter models. It also provides rectifiers,inverters, and converters with common topologies such as buck and boost. These converters use piecewise linear models of the power electronic devices for efficient simulation, and these device models are included so that you can model custom power converter topologies. The power electronic devices can include heat generation by the device and heat transferbetween the device and the environment.

Alstom Generates Production Code for Power Converter Controller (User Story)
Alstom engineers reduced development time by 50%, generated defect-free, safety-critical code, and verified behavior under a range of conditions, including faults.

AC-DC-AC PWM Converter (Example)
A 60 Hz, voltage source feeds a 50 Hz, 50 kW load through an AC-DC-AC converter with a rectifier and an inverter controlled by a PI voltage regulator.

Quantifying IGBT Thermal Losses (Example)
Generate a temperature profile based on switching and conduction losses in an insulated-gate bipolar transistor (IGBT).

Motors

Simscape Power Systems provides models of synchronous and asynchronous three-phase machines. You can also enable nonlinear effects such as saturation. Standard and simplified models let you select the level of fidelity appropriate for your task. The models offer multiple parameterization methods that let you enter the values you have available, and the blocks calculate per-unit base values.

Simscape Power Systems AC and DC electric drive models with key parameters available in a dialog box (example shown bottom). Models can include or neglect switching effects.

Drive Controllers

Models of elements in drive controllers are provided in Simscape Power Systems, including current controllers, speed controllers, and modulators. You can use these blocks to implement control strategies such as field-oriented control, vector control, and direct torque control. The models enable you to incorporate or neglect the effect of drive circuit switching on your system.
