New features and changes introduced in this version are described here:
The machines library of powerlib contains a model of a Switched Reluctance Motor that allow you to model three typical configurations of such a motor. The library also contains a model of a Single-Phase Asynchronous Machine that can be configured as a split phase, a capacitor-start, or as a capacitor-start-run motor mode.
The core saturation can now be specified for the Asynchronous Machine block when the block is used in a phasor simulation. The saturation model of the Asynchronous Machine is based on the fundamental component of the current and does not include the third harmonic. The saturation parameter is available only when the simulation is in phasor mode. When the Powergui block is set to continuous or discrete mode, the parameter is disabled in the mask of the block.
The Permanent Magnet Synchronous Machine block allows you to specify a trapezoidal flux distribution as an alternative to the sinusoidal flux option of the previous version of the block.
The Series RLC Branch block, Parallel RLC Branch block, Three-Phase Series RLC Branch block, and Three-Phase Parallel RLC Branch block now have a new parameter that allows you to directly specify the elements that are present in the branch: the R, L, C, RL, LC, RC, and RLC configurations can be specified. It is no longer required to specify an Inf value for the Capacitance in a Series RLC Branch block to get rid of the capacitor device in the branch or to specify 0 value of resistance to get rid of the resistor of a Parallel RLC Branch block.
The seven DC drives blocks, and the AC2 and AC6 AC drives of the electricdrivelib library now have a new parameter that allows you to specify average value models, as opposed to detailed models, for the converters.
To switch to the average-value representation, open the block dialog box and set the Model detail level option in the bottom portion of the dialog box to Average.
The Discrete System block and the Machine Measurement Demux block are no longer supported in V4.1 (R14SP2+).
The table below indicates blocks that are obsolete as of the current version, and lists blocks that you can use as replacement for the obsolete blocks.
