FACTS (flexible AC transmission systems) technology offers an alternative way in damping low frequency powersystem oscillations. Oriented to the modulation control of UPFC (unified power flow controller), this paper constructs afuzzy modulation controller (FMC) with fuzzy logic incorporated, so as to damp the power oscillations of tie-lines andimprove the dynamic stability of the whole system. The structure of FMC is given in detail, and the key parameters are tunedby gradient descent training method. Furthermore, taking the feature of the shunt--series structure of UPFC intoconsideration, the concept of combined modulation is proposed to get better damping performance than the single--elementmodulation. The digital simulation conducted on a multi--machine interconnected power system shows that the designed FMCis efficient in damping power oscillations, and has better performance than the linear counterpart when operating pointchanges. The simulation results also show that the combined modulation is better than shunt or series modulation.This project is jointly supported by National Scaling Project--B and PGC Foundation of Hong Kong SAR.

A coordinated recovery strategy for multi-infeed HVDC systems under large disturbance is proposed.It has following features.A feed-forward loop is added to original PI controller to realize the coordinated control between the two controlled variables at the two control ends.A constant AC voltage control is applied for a short period after the AC fault is removed.A staggered recovery strategy is adopted for different HVDC subsystems with different restart time intervals,which are optimized using the steepest descending gradient search method.The simulation results for a tri-infeed HVDC system are given,which show that the recovery performance,with the proposed coordinated recovery strategy,has been improved a lot compared with the conventional control strategy.
