Based on modal analysis, this paper analyzes the shortcoming existing in the modal observability of the control performance of traditional PSS (power system stabilizer). This is further explained by transfer function zero action. To tackle this problem, wide area measurement is adopted as feedback signals to improves the modal observability, and thus damp the inter-area oscillation. Finally, eigenvalue analysis is made on a typical three area interconnected power system to test the performance of different controller and wide area measurement based controller is proved to be effective.
