Geographical monitoring of Electrical Energy Quality determination: the problems of the sensors

""The problem of the electrical energy price, evaluated considering its quality, has been analyzed in this article. The electrical energy quality is directly defined by the customers as an output of a complex procedure which uses as inputs both the power quality technical parameters and the human experience. The procedure shows as the accuracy in the quality definition is strongly related with the accuracy of the sensors used for the power quality measurements, especially regarding their synchronization. An analysis of the synchronization of the sensors placed on a spread territory is also made. A solution for a centralized control of the sensors time course is also suggested.""

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.
