Wide-area Measurement System can retrieval the real time dynamic and static information of the large scale power system under the same time reference, helping to resolve the problems of the dynamic analysis and control for an interconnected power system, especially the low-frequency oscillation. However, communication delay is a non-ignorable factor for the stability of wide-area control. In this thesis, the dynamic model for interconnected power system considering the time delay was established, Simulation of large and small disturbance to a typical four-generator two-area testing system indicates that wide-area damping controller has a strong capability of damping area oscillation and good robustness even at the long wide-area signal time delay.
