doi:10.1109/TIM.2010.2060770

In this paper, some statistical properties of procedures defined to detect voltage dips in electric power systems are discussed. First, a theoretical model of the root-mean-square based test proposed in the IEC 61000-4-30 is provided and validated. Then, an alternative detection algorithm, based on the Generalized Likelihood Ratio Test (GLRT), is proposed, and compared to the 61000-4-30 test. It is shown that the GLRT may provide competitive performance, in terms of Receiver Operating Characteristic (ROC), if compared to the standardized procedure.

Then, an alternative detection algorithm, based on the Generalized Likelihood Ratio Test (GLRT), is proposed, and compared to the 61000-4-30 test. It is shown that the GLRT may provide competitive performance, in terms of Receiver Operating Characteristic (ROC), if compared to the standardized procedure.
