Wide Area Measurement System

With the rapid development of interconnected power grid, the phenomenon of power system low-frequency oscillation appears unavoidably. Then, the appearance of wide-area measurement system provided a supporting technology for better scout low-frequency oscillation system and better recognize the oscillation mode . In this paper, the existing oscillation mode identifying methods are analyzed from the viewpoint of calculation speed, criterion, calculation accuracy, etc. Mainly compared the applicability of two methods, Prony and ESPRIT . Based on the above research, a new idea of monitoring power system low frequency oscillation based on WAMS is put forward in this paper.

Damping Controller

To damp the inter-area low-frequency oscillation in power systems, a wide-area damping supplementary inter-area controller, based on output prediction observer and LMI method, was designed in this paper. Simulation results of a test system show that the wide-area damping controller can well damp inter-area low-frequency oscillation, and is insensitive to time-delay to some degree.
