Power System Blockset 2.1 Release Notes

New Features

Note    Power System Blockset was renamed SimPowerSystems as of Release 13, Version 2.3.

This section introduces the new features and enhancements added in the Power System Blockset Version 2.1 since the Power System Blockset Version 1.1 (Release 11.0).

Faster Circuit Topology Analysis

Power System Blockset now dramatically speeds up circuit topology analysis, allowing your power system simulations to start much more quickly. The blockset can now handle larger, more complex models with reduced simulation overhead.

Simulation Enhancements

Powerful discretization features have been added to Power System Blockset. These can dramatically speed up your simulations - especially those with Power Electronics blocks.

• In addition to the continuous simulation of power systems, you can now also discretize your models, using the fixed-step trapezoidal method (illustrated in the Current Transformer Saturation demo). See the Powergui block in the Power System Blockset library for more information.
• You also now have- especially those with power electronics devices. the ability to generate code from discretized Power System Blockset models through Real-Time Workshop for even more simulation speed.

The forward voltage of discretized power electronic devices (e.g., diode, thyristor, IGBT, and GTO) is now simulated in all cases, including discrete and continuous (with Lon=0).
