The evaluation of electrical energy flows is at the base of all operations connected to commercial transactions on the energy market. Typically, the measurement apparatuses are made and characterized to work in ideal sinusoidal conditions. But, with increasing diffusion of power electronic devices, the typical characteristics of a power network are far from sinusoidal ones. With the aim to link the cost of energy to the level of power quality, it is necessary to determine the energy but also the indexes which characterize the power quality. In this paper the design and implementation of a multi-processor measuring instrument based on multiple digital signal processors (DSPs) is discussed. This system can embody a number of special signal processors and analog I/O modules, specifically designed to obtain the flexibility and scaling ability to meet the needs of real-time measurement applications and low cost. After a prototype description, part of the analysis algorithm is reported. The paper is completed by preliminary results of metrological characterization.
