Decomposition-coordination model for optimal operation of pumping stations

In consideration of the coexistence of the fixed and adjustableblade axialflow pumps at the Taizhou Pumping Station, a double layer decompositioncoordination model was established for the optimal operation of the pumping station based on its conventional operational mode and characteristics of pump set allocation. With the model, different optimal solutions can be found for different layers. The calculated result shows that the model and the principle of optimization presented can ensure rational and economical operation of the pumping station with the original facilities.
