The Design of the OVPD in Urban Rail Transit Based on the Safety and Reliability

摘要：

According to the real situation of domestic metro DC traction power supply system, an accurate system equivalent model was set up. Based on this model, the short circuit current and the distribution of rail voltage were calculated well and truly under short circuit condition. The main preferences of OVPD, such as the action characteristic and the withstanding current of short circuit, can be analyzed in view of system. Moreover, the method can also be used to analyze the action process of all OVPDs. Compared with engineering practice, it has been proved the proposed method has fairly high practical value.
