摘 要：This paper proposes a design method for a wide-area measurements based power system stabilizer to improve the mode of concern, which is the dominant inter-area mode, in each system operating point. The design method, which is an iterative one, includes two steps: feedback signal selection and controller parameter tuning. The principle of the feedback signal selection is to maximize the residue of the mode of concern for the feedback signal while minimizing that of other modes. Then the tuning process can focus on only the mode of concern. The proposed method has been tested on the day time operating point of the IEEJ West 10-machine system. The result shows that the designed controller can improve the mode of concern significantly, while it can not affect much the others.
