This demo illustrates use of the Three-Phase Transformer Inductance Matrix Type block to model a three-phase core-type saturable transformer. It also demonstrates that using three single-phase transformers to simulate a Yg/Yg core-type transformer is not acceptable. Solid-Oxide Fuel Cell Connected to Three-Phase Electrical Power System (power_SOFC) Mechanical Coupling of Synchronous Generator with Exciter System (power_SM_exciter) Three-Phase Core-Type Transformer (power_Transfo3phCoreType) 17 SimPowerSystemsTM Release Notes Three-Phase Matrix Converter (power_three_phase_matrix_converter) This demo illustrates a three-phase matrix converter driving a static load. Indirect space-vector modulation allows direct control of input current and output voltage and hence allows the power factor of the source to be controlled. As a result, the demo outputs the unity power factor at the source. This demo illustrates the use of a shunt active harmonic filter (AHF) to minimize the harmonic content propagated to the source from a nonlinear load. Three-Phase Active Harmonic Filter (power_active_filter) 18 Version 4. 5 (R2007b) SimPowerSystemsTM Software Version 4. 5 (R2007b) SimPowerSystems Software This table summarizes what's new in Version 4. 5 (R2007b): New Features and Changes Yes Details below Version Compatibility Considerations Yes--Details labeled as Compatibility Considerations within descriptions of new features and changes, below. Fixed Bugs and Known Problems Bug Reports Includes fixes Related Documentation at Web Site No New features and changes introduced in this version are · "New Battery Block" on page 19 · "New Stepper Motor Block" on page 20 · "Three New Transformer Blocks" on page 20 · "New Measurement Option Available for the PI Section Line Block " on page 21 · "New SimPowerSystems Demos" on page 21 · "Renamed psbhysteresis Command" on page 22 New Battery Block A new block, Battery, has been added to the Electrical Sources library. It implements a generic battery that models most popular battery types, such as Nickel-Metal-Hybride, Lead-Acid, Lithium-Ion, and Nickel-Cadmium. User-Defined Battery type allows you to modify detailed parameters to represent any particular discharge characteristics. The Hybrid Electric Vehicle (HEV) Power Train demo (power_HEV_powertrain), which was introduced in Version 4. 4 (R2007a) and shows a multi-domain simulation of a HEV power train based on SimPowerSystems and SimDriveline blocks, has been modified to use the 19 SimPowerSystemsTM Release Notes Battery block. It is now called Hybrid Electric Vehicle (HEV) Power Train Using Battery Model. New Stepper Motor Block A new block, Stepper Motor, has been added to the Machines library. Depending on the motor configuration specified by the Motor type parameter, this block models: · A two- or four-phase permanent magnet or hybrid stepper motor · A three-, four-, or five-phase variable reluctance stepper motor Three New Transformer Blocks Three new transformer blocks have been added to the Elements library: · Grounding Transformer implements a transformer that is used to provide a neutral in a three-phase, three-wire system. The transformer consists of three two-winding transformers connected in a zigzag. The nominal voltage of each of the six windings is Vn/3. · Three-Phase Transformer Inductance Matrix Type (Two Windings) represents inductive coupling between windings located on different phases of a three-limb or a five-limb core. It also allows modeling of a three-phase transformer built with three single-phase units (no coupling between phases). The transformer R L parameters are obtained from no-load excitation tests and short-circuit tests in positive- and zero-sequence. When core type is specified as Three-limb or five-limb core, the transformer is modeled by 9 coupled windings; otherwise, it is modeled by 3 sets of 2 coupled windings (Z0=Z1). · Three-Phase Transformer Inductance Matrix Type (Three Windings) represents coupling between windings located on different phases of a three-limb or a five-limb core.

[. . . ] Such blocks serve as interfaces between the part of your model connected by Simulink signal lines and the part connected by electrical connection lines. Compatibility Considerations Converting Version 2 Models to Version 3. Version 3. 0 provides the psbupdate command to convert your old Version 2 models to the new block library and interface of Version 3. See the HTML or PDF forms of the special documentation for model conversion. If you are viewing these Release Notes in PDF form, note that the HTML form of the Release Notes provides links to both forms of the conversion guide. [. . . ]
