Abstract

The invention provides a motor train unit traction converter performance detection method and device and terminal equipment. The method is applied to the field of data processing, and comprises the steps of obtaining target detection data of a motor train unit traction converter, wherein the target detection data comprises a target motor train unit speed and target performance influence information of multiple groups of traction converters corresponding to the target motor train unit speed, determining a target performance index value of a traction converter of the motor train unit based on the target speed of the motor train unit and a preset performance detection model, determining theoretical performance index values of the traction converters of the motor train unit based on the target performance influence information of the multiple groups of traction converters, and detecting the performance of the traction converter of the motor train unit according to the target performance index value and the theoretical performance index value. According to the motor train unit traction converter performance detection method and device and the terminal equipment provided by the invention, the working state of the traction converter can be evaluated more accurately.

Description

technical field [0001] The invention belongs to the technical field of data processing, and more specifically relates to a performance detection method, device and terminal equipment of a traction converter of an EMU. Background technique [0002] The traction converter is one of the key components of the EMU. It is installed at the bottom of the train EMU. Its main function is to convert the electric energy between the DC system and the AC system, and convert the DC power from the catenary into a three-phase AC power. Realize the starting, braking and speed regulation control of the AC traction motor. [0003] As a key component of the EMU, the performance of the traction converter directly affects the safe and punctual operation of the EMU. If its efficiency is reduced, it will directly affect the power of the traction motor, and will also affect the power supply of the vehicle's medium-voltage load. Therefore, monitoring and evaluating the performance status of traction...
