Abstract: Utilizing the complex network theory, a novel method of vulnerability analysis in the distributed and complex electromechanical system based on the network topological property was proposed. Complex electromechanical system in process industry was analyzed from system and network perspective. The topological structure characteristics of system network and its influence to faults propagation were investigated. Subsequently, the loads and vulnerability coefficient of nodes were defined to study the inherent vulnerability of the electromechanical system. A case study of Tennessee-Eastman (TE) process was provided to illustrate the analysis & application process of the proposed method. Its effectiveness was also verified. The results showed that the method could find the critical node and the crisp node of system, which could be used for the safety control and failure prevention of the system.
