Characterization of the cabling on industrial power networks for EMI simulation

Abstract : This work analyses the EMI problems that may arise in the large electric networks on industrial plants, taking into account the switching harmonics injected in these systems by power converters. The harmonics were studied in the frequency band from DC up to a few tens of MHz.To model the propagation of the switching harmonics in long electric cables, an accurate and computationally efficient simulation method is proposed. It is fit to simulate the behavior of medium frequency parasitic signals in large cabling networks, e.g. on industrial plants, buildings, and others. This method can be useful in the designing of such systems, contributing to the development of protection measures against dysfunction or damage that may be caused by EMI phenomena in the network.
