An emission management framework for implementing a large railway system with interface complexity

This paper presents a framework for a life cycleapproach electromagnetic compatibility (EMC) management to control the overall emission of the modern railway system to external environment. With a large number of electrical equipment interfaces following integration of mechanical and electrical subsystems, cooperation across all disciplines during system implementation through key EMC activities is described at each project development phase to guarantee the success of a large-scale project EMC safety assurance. A case study of a large Mass Rapid Transit project is examined to illustrate how the framework may be applied. The validation of safe railway system emission is demonstrated through positive system integration test results under EN 50121-2 criteria. The framework flexibility to accommodate foreseeable impacts of future change is also discussed.
