7.2.3

Complete List of Changes in ARTEMiS 7.2.3

• Compatibility with RT-LAB 11.2.3
• Renamed SSN Ground Referencing Resistor block.
• Fixed certain RT-LAB compatible online demos: ssn_9LevelDrive_xfozigzag, ssn_DFIM_wind_turbine_with_crowbar and SSN_IEEE_123Node.

• Correction to SSN resistance model.

7.2.2

Complete List of Changes in ARTEMiS 7.2.2

• Compatibility with RT-LAB 11.2.2
• Compatibility MATLAB 2011b, 2015a-SP1 (prefered version), R2016b, R2017a (64 bits)
• SSN solver and discretization methods are now used for all-electric subsystems, even if the model is not modeled with SSN (flag DISABLE_SSN_FOR_NON_SSN_MODELS can be used to use old state-space S-function)
• SSN initial conditions now set to 0 automatically
• Added scientific paper section to the demos
• Added benchmark section to the demos
• New Kundur 4-machine, 2-area model with SSN synchronous machine
• New IEEE 123 node test feeder using SSN demo
• SSN printout of matrix invertibility condition number when USE_MFILE_SSN_SFUNCTION=1 is set in the workspace
• Updated 3 winding 3-phase OLTC transformer demo using SSN: now without S-function builder block.
• Bipolar HVDC with switched filter banks online demos modified to have a better numerical response with LDLT solver.
• 3-level NPC TSB model: ground connections are now implicit.
• Code correction in SSN-OLTC model v2 (without S-function)
• New SSN demo containing distributed parameter line with breakers and faults at both ends

7.2.1

Complete List of Changes in ARTEMiS 7.2.1

• Compatibility with RT-LAB 11.2.1
• Major scientific papers at ARTEMiS-SSN now accessible in the on-line demo section
• SSN benchmarks accessible in the on-line demo section
• Various small corrections to demo models
• RT-LAB snapshot functionality for Simscape Power Systems sfun_discreteVariableDelay S-Function. This allows support for the following blocks: in powerlib_meascontrol/Measurements: Fundamental(PLL-Driven), Mean(Variable Frequency), Positive-Sequence(PLL-Driven), Power (PLL-Driven, Positive-Sequence); and also in powerlib_meascontrol/PLL blocks.

7.2.0

Complete List of Changes in ARTEMiS 7.2.0

• Compatibility with RT-LAB 11.2
• Compatibility MATLAB 2011b, 2015a-SP1 and R2016b (prefered versions)
• New LDLT Factorization option in SSN to improve real-time speed.
• Adding Delayed Speed Term option in most SSN rotating machine models (SM, DFIM, and PMSM)
• Major bug correction for SSN solver affecting Rotating machine models mainly: the model admittance matrix was copied in the global system admittance matrix in a transposed way. The copy of the admittance matrix is now correctly done. This only affects machine models, without delayed speed terms, because these have asymetric matrices.
• Model corrections to SSN-SM and SSN-DFIM to have a delayed discrete B matrice used during SSN model calculation. This delayed B matrice corrects a discrepancy between internally computed current and external ones in the case with the machine connected to very small loads.
• Model updates for SSN-SM: more measurements available
• New SSN Custom models available: Parallel RLC, Series RLC, R, all with on-line changeable RLC parameters.
• New Reconfigurable breaker model available with script and demo. Using this model, one can turn breakers into fixed/closed circuits using a single model running multiple test scenarios.
• Installer correction: IEEE 39 bus 10 machine demo is now really accessible
• Removal of iteration printouts by default in offline mode. op_ssn_print_iteration_info variable must be set in workspace now.
• HELP available for iMOV, TSB 2-level, TSB 3-level and other blocks
• SSN Dynamic load demo available. More stable than the injection-based dynamic load of SPS. (beta version)
• New RT-LAB and ARTEMiS SSN Monte-Carlo test demo using the snapshot feature
