Abstract
- This paper derives an improved version of a periodogram detector for detecting forced oscillations (FOs) in power systems using synchrophasor measurements. FOs are usually periodic in nature and are often accompanied with multiple harmonic components. This harmonic information of FOs is incorporated into the proposed periodogram detector, which significantly improves its detection performance for a given probability of a false alarm. The original periodogram detector carries out detection of each component of FOs separately, even though they are related through their harmonics. In the proposed periodogram detector, the detection algorithm is re-derived by incorporating harmonic information such that the detector now looks for a combination of harmonic components of FOs for detection. This derivation shows a significant improvement in the detection performance of the proposed periodogram detector as compared to the original one. This is also illustrated by the results obtained by implementing the proposed periodogram detector on the simulated and real-world PMU measurements.
