Analysis of robustness in electromagnetic compatibility supernetwork

Study of robustness has been conducted across many fields of science. Electromagnetic compatibility (EMC) supernetwork is a network composes by different characteristic units. The robustness of EMC supernetwork determines the stability of the transmission of the interference signal. In this paper, a railway vehicle EMC supernetwork model is built based on the EMC character. Then two experiments model are conducted based on random interference and deliberate attack to analyze the robustness of the EMC supernetwork. The simulation result shows that the EMC supernetwork is robust to random interference, while the strong vulnerability to deliberate attack. The attack mode according to the betweenness of the order is the most effective way to change the network performance. It provides a reference meaning for the rectification of the complex EMC problem.
