For the short-shunt configuration, the authors of  concluded that adding series capacitors ensures a successful IM starting and highlighted the presence of the subsynchronous
resonance phenomenon due to large variations in the total load impedance for such a topology.
As they are being pushed to these new extremes of operation the designs must also adapt to accommodate the consequences of these extremes including increased rotor flexibility and an increased likelihood of subsynchronous
Figures 6 and 7 show the capabilities of the NPI controller to improve system damping, MPPT, LVRT, and its contribution to network support at both subsynchronous
and supper synchronous conditions.
This device is considered as one of the most effective FACTS and is widely used to regulate the power flow in transmission lines, dampen the power oscillations, mitigate subsynchronous
resonance (SSR), enhance power system stability, and so forth by changing the reactance of transmission line .

mode or partial load mode at below rated speeds: the stator of the DFIG supplies power to the grid and slip power to the rotor via the converters and slip rings.
Between 1966 and 1968, we launched twenty-seven DSCS I satellites--as many as eight at a time--into a subsynchronous
