| Summary: | Aiming at the internal overvoltage phenomenon during high-speed train operation, the overvoltage formation mechanism and its influencing factors were analyzed by taking the case of the overvoltage in passing neutral section and the overvoltage of pantograph raising and dropping, and a simulation model for verification was built. In order to reduce the internal overvoltage of high-speed train, three measures of parallel blocking high-pass filter in neutral section, adopting advanced co-phase traction power supply system and selecting suitable roof voltage transformer were proposed. The results showed that the internal overvoltage of the high-speed train was related to the voltage phase of the catenary at the time of operation and the impedance of the voltage transformer, the three overvoltage suppression methods proposed could effectively reduce the overvoltage with simulation. |
