GENQEC Generator Model
(A Combination of GENQSC & GENESC)
Outline
2
o What is GENQEC Model
o GENQEC model structure
o Analysis and simulation results
o Simulation results using TSAT (DSATools)
o Conclusion and future work
GENQEC Model
3
o Combination of GENQSC and GENESC proposed earlier
o Based on 2nd-order generator equivalent circuits in IEEE Std 1110
o Same base as GENROU, GENROE, GENSAL and GENSAE models
o Magnetic saturation considered on both stator and rotor inductance terms
o Quadratic or exponential saturation function selectable in model data
o Suitable for representing both round-rotor and salient-pole units
o High accuracy of field current across whole generator operating range
o Field current compensation factor derived from generator zero-power-
factor characteristics, or fitted from field measurement data
o Appropriate for generator model validation using field test data

GENQEC (GENQSC) Results
6
o Derivation process from equivalent circuit to model block diagram given
in reference publications [3] and [4]
o GENQSC steady-state field current accuracy improvement
demonstrated in reference publication [3]
o GENQSC dynamic performance improvement compared in reference
publication [4]
o GENQSC model rotor angle compared in reference publication [5]
using simple magnetic saturation method on both d- and q-axis
o GENQEC model simulation results using TSAT (Powertech Labs
DSATools) presented on following pages
GENQEC TSAT Simulation Results
7
o Results on round-rotor and salient-pole in-service generating units
o Generating unit model parameters previously validated through field
testing, based on manufacture-provided generator parameters
o Simulation results compared with field measurement where applicable
o Compensation factor for GENTPJ & GENQEC was chosen to have high
field accuracy at highest load with high field current
o Compensation factor in GENQEC model has no impact on rotor angle
o Field tests simulated:
o Offline AVR Voltage reference step response
o Online AVR voltage reference step response with and without PSS
o Assumed short-circuits at generator terminals for 0.1 second

Conclusions and Future Work
26
o Better modeled steady-state field current accuracy than all existing 2nd-
order generator dynamic models using a field compensation factor
o Fairly accurate simulated generator rotor angle by simply applying open-
circuit saturation characteristic to both d- and q-axis inductance terms
o Equivalent circuit and block diagram representations facilitate the
application of operational impedance and small-signal stability analysis
o GENQEC simulated dynamic response closely match field measurements
from generator model parameter validation test
o Next: Good results expected for extensive testing of GENQEC using
generator model validation test results
o Next: Acceptance and implementation of GENQEC in commonly-used
power system analysis software
