This paper describes a method for the evaluation of the economical losses caused by voltage sags in an industrial facility in which the presence of adjustable speed drives (ASD's) is significant. The nature of the data that must be provided in order to have practical information about system reliability at the point of common coupling (PCC) is analysed in detail. Then, the adequate methodology for considering the technical and economical consequences of voltage sags on the production is described for the case of critical drives.
The analysis that is carried out in this work is also useful for making critical evaluations on the interest that the different solutions (ride-through alternatives)oriented to the improvement of performance of these apparatus can have in a particular case.
