Optimal Operation of a Single Unit with an Adjustable Blade in an Interbasin Water Transfer Pumping Station Based on Successive Approximation Discretization for Blade Angle

Table 4

Analysis table of optimal operation benefit under typical operation conditions.

Daily average head (m)	Water pumping load (%)	UMOC saving compared with the first time of optimization (%)	Reduction of actual TWPQ meeting water pumping load (10^4m^3)		Total cost saving of water pumping (RMB)
