Abstract With the rapid development of urban rail transit, the safety problems caused by stray current and rail potential are increasingly serious. However, the stray current and rail potential solutions are difficult to verify in actual metro system. In recent years, the corresponding simulation systems have been extensively studied by researchers around the world. But the existing simulation systems lack the consideration of the train operation conditions and grounding schemes. Therefore, the applications of the simulation systems are limited. For these reasons, a novel bidirectional variable resistance module is firstly proposed to simulate the train movement under different operation conditions. Then three new dynamic simulation systems are further proposed in combination with the grounding schemes of the traction substation. The application scenarios, evolution laws, parameter selection and control strategies are analyzed in detail. The simulation and experimental results show that the above mentioned simulation systems can be employed not only to analyze the effects of stray current and rail potential, but also to hardware evaluations. It shows good application prospect in urban rail transit study.

Key words： Urban rail transit stray current rail potential dynamic simulation system bidirectional variable resistance module
