Damping of Power System Sub-Synchronous Resonance Oscillations through Fuzzy-Logic Dynamic Brake Control
نویسندگان
چکیده
Dynamically switched resistor banks connected to the generator transformer bus are known to improve transient stability of the power system. In this article, a braking resistor control strategy designed through fuzzy logic control theory has been proposed to damp the slowly growing subsynchronous resonant (SSR) frequency oscillations of a power system. The proposed control has been tested on the IEEE second benchmark model for SSR studies. The generator speed variation and acceleration were employed as the input to the controller. It was observed that the fuzzy controller provides very good damping control.

متن کاملStability Improvement During Damping of Low Frequency Oscillations with Fuzzy Logic Controller
Low Frequency Oscillations (LFO) occur in power systems because of lack of the damping torque in order to dominance to power system disturbances as an example of change in mechanical input power. In the recent past Power System Stabilizer (PSS) was used to damp LFO. FACTs devices, such as Unified Power Flow Controller (UPFC), can control power flow, reduce sub-synchronous resonance and increase...
