This paper focuses on issues arising from the need to automatically analyze
disturbances in the future (smart) grid. Accurate time allocation of events and the
sequences of events is an important part of such an analysis. The performance of a joint
causal and anti-causal (CaC) segmentation method has been analyzed with a set of real
measurement signals, using an alternative detection technique based on a cumulative sum
(CUSUM) algorithm. The results show that the location in time of underlying
transitions in the power system can be more accurately estimated by combining CaC
segmentation methods.
