The method of the invention is applied to a tidal pumping station, saving 3% to 9% of operating costs.

Description

technical field [0001] The invention belongs to the technical field of pumping station energy saving, and relates to a tidal pumping station unit number + variable angle daily optimization operation method based on time-optimized partitions. On the premise of the total pumping water requirement and the safe operation of the pumping station, the determination method of the variable number + variable angle daily optimal operation plan based on the variable working condition time optimization partition is given with the goal of minimizing the total operating cost of the tidal pumping station system. Background technique [0002] my country has built many large pumping stations along the river and along the Tongjiang Canal. These pumping stations play a key role in irrigation, drainage and water diversion, but their characteristic is that the lift varies with the tide level, with two high tides and two low tides a day, and two high tides and two low tides a day. At present, the o...
