Embodiment
[0026] This embodiment is a method for controlling the gate of a large-scale water conveyance open channel based on the principle of superimposed wave elimination. The basic principle of the method is based on the principle of superposition and cancellation of waves. By reasonably determining the operating time interval between the control gate and the water diversion gate, the positive wave / negative wave generated by the opening / closing of the control gate and the negative wave generated by the opening / closing of the diversion gate / Positive waves meet, superimpose and cancel at the water diversion, so as to effectively reduce the water level fluctuation near the water diversion.
[0027] The opening or closing of the control sluice and diversion sluice is the main factor causing the fluctuation of the channel water level and flow, and its effect is propagated in the form of moving waves. The speed of the moving wave determines the time when the water level and flow at each ...
