About Dynamics Model Validation
Sept 22, 2014

Dynamics model validation is performed with Single Machine Infinite Bus (SMIB) model.
The SMIB model has:
(1) 3 buses:
    Bus number,   Bus name,      Voltage(kV),    Type,  PLOAD(MW),   QLOAD(Mvar),  PGEN(MW),   VSET(p.u.),   MBASE(MVA)
    1,            'MACHINE',     20.0,           PV,    0.0,         0.0,          300.0,      1.0,          350.0
    2,            'SUBSTATION',  242.0,          PQ,    1000.0,      200.0,        0.0,        N/A,          N/A
    3,            'SLACK',       242.0,          Slack, 0.0,         0.0,          ~700.0,     1.0,          10000.0
(2) 1 transformer:
    From bus,  To bus,   Gmag(pu),  Bmag(pu), R(pu),   X(pu),   Tap1(pu), Tap2(pu)
    1,         2,        0.0,       0.0,      0.0001,  0.008,   1.0,      1.0
(3) 2 lines
    From bus,  To bus, Ickt,  R(pu),   X(pu),   Total charging(pu)
    2,         3,      '1',   0.001,   0.02,    0.01
    2,         3,      '2',   0.001,   0.02,    0.01

Event is set as:
Bus fault at line 2-3 '1' (at bus 2 side)  with fault P+jQ=0+j(-2e9) MW/MVar, and cleared after 0.05s with line trip

Machine at bus 3 is modelled as GENCLS with H=999.0, D=0.0.

Machine at bus 1 is tested with different dynamics models. Model parameter can be found in the validation spreadsheet.

For machine model validation, generator models are provided.
For AVR, turbine-governor, PSS, and other models, the parameter of test model is listed in validation spreadsheet. And the generator of bus 1 is modelled as GENROU with:
      1 'GENROU' 1     5.7000      0.30000E-01  0.35000      0.50000E-01
          3.000        2.000      0.25400      0.24100      0.48000E-01
         0.48000E-01  0.29000E-01  0.29000E-01   0.0000       0.0000 
No saturation is modelled for the GENROU model.
