Abstract: In order to comprehensively improve the efficiency and safety of coal transportation, thermal power plants have further renovated coal-handling dumpers. After the renovation, PLC technology can be used to control the daily operation of coal-handling dumpers, scientifically design the electrical control system of coal-handling dumpers and implement it in the program, which can lay a solid foundation for the efficient operation of thermal power plants. Based on this, this article expounds the concept of PLC technology, analyzes the control types of PLC technology, clarifies the automatic control functions of coal-handling dumpers, mainly including coal-loading automation, coal-blending automation, start-stop automation, etc., and applies PLC technology to the transformation of the electrical control system of coal-handling dumpers in thermal power plants, so as to design reasonably the main program of dumpers, fully exert the role of the main program of dumpers, improve the operating efficiency of dumpers, and ensure the smooth progress of coal transportation work.
