    摘要: An electronic protection device for electric power distribution grids, the electronic protection device being adapted to control one or more switching devices in an electric power distribution grid and being capable of communicating, at local level, with one or more sensors or electronic devices of the electric power distribution grid and, at remote level, with a remote computerised platform. The electronic protection device is adapted to receive first grid monitoring data indicative of physical quantities related to the operation of the electric power distribution grid from the sensors or electronic devices, the first grid monitoring data including at least measured values indicative of a line current flowing along an electric line of the electric power distribution grid. The electronic protection device is adapted to carry out a predictive monitoring procedure of the operating conditions of the electric power distribution grid.

    摘要: A method for modelling a coating process including a plurality of coating parameters, includes the steps of: dispensing, by the coating process and during K work cycles, a coating on each of K pieces of objects to thereby obtain K pieces of coatings; recording, during each of the K work cycles, coating variable values of p coating parameters at M instances to thereby obtain recording results; and measuring at least one coating property at m locations of each of the K pieces of coatings to thereby obtain measurement results. The method is characterized by the step of determining a digital twin of the coating process on the basis of the recording results and the measurement results. By using results from a large amount of classical quality control measurements together with corresponding coating parameter information, a digital twin of the coating process can be determined through statistical processing of such big data. The digital twin) may be used either for automatic adjustment of the coating parameters to obtain an improved coating quality, for prediction of the coating quality right after a work cycle to obtain an improved quality control, or for both.
