Description

technical field [0001] The invention relates to the field of hydropower generation, in particular to a maintenance device for a hydropower station with an optimized control system. Background technique [0002] Hydropower generation uses rivers, lakes, etc. to flow water with potential energy from high places to low places, convert the potential energy contained in it into kinetic energy of water turbines, and then use water turbines as the driving force to drive generators to generate electricity. Use water power to drive the hydraulic machinery to turn, and convert the water energy into mechanical energy. If another machine is connected to the water turbine and rotates with the water turbine, electricity can be generated. At this time, the mechanical energy is converted into electrical energy. [0003] In the field of hydroelectric power generation, due to the vast area of ​​the power station, the maintenance devices of hydropower stations, especially the maintenance vehic...
