The present invention discloses a converter control device for a motor train unit. The device comprises an analog quantity acquisition and processing unit plug-in, a pulse conversion unit plug-in, a network side signal processing unit plug-in, a machine side signal processing unit plug-in, a real-time control unit plug-in, a system management unit plug-in and a digital quantity input and output unit plug-in; the analog quantity acquisition and processing unit acquires and processes various kinds of analog quantity signals including voltage or current signals; the pulse conversion unit plug-in generates converter pulse control signals and processes fault signals; the network side signal processing unit plug-in unit carries out judgment according to the signals of the analog quantity acquisition and processing unit plug-in, and carries out protection; the machine side signal processing unit plug-in collects motor speed signals, carries out judgment according to the signals of the analog quantity acquisition and processing unit plug-in and carries out protection; the real-time control unit plug-in and the system management unit plug-in achieve converter system control and protection; and the digital quantity input and output unit plug-in achieves main circuit breaker and contactor signal feedback and control. With the converter control device for the motor train unit of the invention adopted, real-time control on the rectifier, inverter and auxiliary inverter of the electric system of a train can be realized, the configurations of the unit control plug-ins can be flexibly selected according to different control requirements, and the requirements of a majority of applications in the rail transportation field at present can be fully satisfied.
Description
technical field [0001] The invention relates to the field of rail transit electrical control, in particular to a main and auxiliary integrated converter control device and system applied to rail transit vehicles including electric train units and electric locomotives. Background technique [0002] At present, in the converter control system in the field of rail transit, the main converter and the auxiliary converter mostly adopt a discrete control structure, which requires a separate control unit. Although the discrete converter control unit can fully meet the control requirements, there are still some shortcomings. At the same time, with the rapid development of technology today, the rail transit field has increasingly stringent requirements on the volume, weight, cost, and integration of converters. Therefore, there is an increasingly urgent need to develop an integrated converter control device. The integrated converter control device shall include system management, gr...
