| Abstract: | Aiming at the operating requirements of the mine hoists being used under the switching mode of industrial power grids and generating sets, a mine-hoist variable frequency control system based on Siemens S120 four-quadrant converter configurations of brake units and braking resistors are presented. The whole system switching logics, configurations and practical applications are analyzed. The system not only satisfies the requirements of the mine hoists of fully saving energy and fully reducing consumption, but also ensures the safe and reliable ability of the mine hoists under the emergency power supply of the generating sets. The system has been widely used in practice and has well application prospect. |
