IEEE first benchmark for subsynchronous resonance(SSR) study

Has anyone modeled IEEE first benchmark for subsynchronous resonance study in Simulink Specialized power systems? I have built one model myself. Capacitor voltage and generator current looks like the paper very much but generator torque and the torque between LPA and LPB do not match the paper very well. Can anyone help me?

I’m not that familiar with SSR network. Some things you can do to improve the model are: double check the parameterization and check the Three-Phase Fault is set up properly. If the currents and voltages are matching the benchmark but not the torque, this might be an indication that either the parameterization is not 100% right or the initialization is right.
