| Abstract: | The mechanism of power system oscillation damping by FESS(Flywheel Energy Storage System) is studied. The simplified dynamic model of FESS is built,the stator flux linkage orientated control strategy is adopted to decouple the control of its active power and reactive power,and the mechanism of power system oscillation damped by FESS is discussed respectively from the physical analysis,the theoretical analysis based on DTA(Damping Torque Analysis) and the graphic analysis based on equal area criterion. The eigenvalue analysis and non-linear simulative results for a single-machine infinite-bus power system with FESS show that,the damping added to either active or reactive power control loop of FESS can effectively suppress the power system oscillation and that added to its active loop has better effect;three analysis methods have identical right conclusions. |
