Mining mechatronics: 35 years of research and production at «Joint Power» company

This article examines the main areas of scientific and engineering activities at «Joint Power» Company, Ltd, and the development of mechatronic systems for new-generation mining excavators, drilling rigs, dump trucks, and dredgers. For AC electric drives, applied to a vector system with an observer based on an extended Kalman filter, methods have been developed for low-speed control, power limiting in the presence of weak power grids, and optimization of energy characteristics. Methods have also been developed for identifying the parameters of asynchronous machines with a locked rotor and the resistance of the overhead power line supplying the excavator. Mechatronic systems ensure high productivity, technical availability, and electromagnetic compatibility of mining equipment. The «Pulsar» information system provides diagnostics of machine components with intelligent data processing, recording of all processes and documentation of machine performance, and remote monitoring. Complete containerized transformer substations, distribution and switching points, equipped with microcontroller-based multifunctional control and protection systems, have been developed for power distribution and connecting mining machines to 6 kV and 10 kV power grids. Test equipment developed by the Company allows for the characterization of individual components: motors, converters, and controls, as well as electric drives, in various test modes. The design and implementation results of advanced automation and control systems for mining equipment are presented. Information on the company's industrial products is provided.
