A Compound Positioning and Splitting Criterion for Power System Oscillation Center with Predicting Function

Abstract:

In this paper, an oscillation center fast positioning method and the criterion that determines whether a system is out-of-step are combined together to put forward a compound oscillation center positioning and splitting criterion with predicting function. Simulation of a classical numerical example of four-machine system in two regions and an actual example of central China-north China power grid proves that this method can pre-locate lines where oscillation center lies after out-of-step operation of the system when the system is oscillating intensely but still keeps synchronized.
