Abstract
This paper describes a frequency response method for analyzing the stability of subsynchronous oscillations in power systems, as modeled by a number of synchronous machines and an extensive series compensated transmission network. This method allows the simultaneous detailed modeling of all machine shafts and control loops, and hence permits investigation of possible interaction in the subsynchronous oscillation frequency band between machines in different plants. An example application of the method indicates that such interactions may, indeed, occur.Keywords
