Geographical monitoring of electrical energy quality determination: The problems of the sensors

Abstract

It has been taken into account the problem of the price of the electrical energy considering its quality. This last is defined by the customers after a complex procedures which considers as inputs both the technical parameters and the human experience. In Following this procedure the final accuracy in the quality definition is strongly related with the accuracy of the sensors used for the power quality measurements especially regarding their synchronization which becomes particularly problematic considering their distribution on spread territory. Moreover we suggest the solutions for a centralized control of their time course.
