要約(日本語): This paper proposes a design strategy 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 strategy, which is based on a concept of adaptive controller, is an iterative method including two steps: feedback signal selection and parameter tuning. The proposed feedback signal selection is based on a optimal problem of maximizing the residue of 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 design framework has been tested on two system operating points of the IEEJ East 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. It is also seen that the design strategy is appropriate for a concept of an adaptive controller.
