Abstract

Several different approaches for the detection of voltage dips in electic power systems have been proposed in the literature to overcome the limits of the procedure proposed by the International Standard, based on the voltage root mean square. In this paper the most promising of these approaches are compared, by computer simulations, in terms of both statistical performance and response time, which is a critical issue for the development of real-time compensation systems.
