Контроль і діагностика стану тягового електропривода

Abstract

During the development of traction electric drive systems of domestic diesel train DEL-02 with traction asynchronous motors the task is to ensure effective control and diagnostics of the diesel train and its elements during operation using modern information technologies. To achieve this goal it was necessary to address the following issues: the definition of the main components and parameters that are subject to control and diagnosis; construction of the structural scheme of the control and diagnostic system; development of methods of control and diagnostics of the state of the diesel train and its elements. Results. To improve the efficiency of operation of diesel trains DEL-02 of domestic production, the system of control and diagnostics of the state of the traction electric drive using modern means of measuring basic parameters was developed. Further processing of the information received is performed by an onboard microprocessor control system. The solutions for the construction of the system that provides control of the required number of technical and economic indicators of traction electric drive without the introduction of additional elements in the scheme of the control system were proposed and substantiated. Control and diagnosis of indicators of the state of traction electric drive was performed by using a neural network.
