【 摘 要 】

This paper proposes a novel method of locating the disturbance source of forced power oscillation based on equivalent electrical distance. Firstly, actual grid nodes are mapped onto complex plane on the basis of equivalent electrical distance theory. Secondly, PMU monitoring nodes are selected according to the defined index of coupling degree of generator and load. Lastly, the disturbance source is effectively located by resolving optimization problem based on Geiger theory on seismology and the half-plane method. This proposed method can be implemented by acquiring and analyzing waveforms of frequency variance of several monitoring nodes, and is of great practical value for actual grid. A simulation for IEEE 30-buses system verified the validity and accuracy of this locating method.
