The research ranges of optimal operation for large pumping stations were analyzed. Energy losses of power transmission and transformation, pumping stations and water transmission should be considered when optimal models are constituted. Under the circumstances of pumping certain discharge or volume, aiming at the lowest operation cost, optimal models were established considering head variation and time-varying electrical price for single or parallel pumping stations and step pumping station system. Research progress of optimization methods to the models was introduced, and the research trends were pointed out.

“…Olszewski [1] investigated optimal operation for parallel pumps in a pumping system using the genetic algorithm, and regulated operation modes by adjusting valve opening, throttling and frequency conversion, aiming to achieve minimal power consumption, flow rate balance and maximum total efficiency. Feng et al [2] discussed the optimal operation of main pump units using the genetic algorithm, giving electricity cost savings of 4.73−31.27% in the schemes of adjusting blade angles and time-varying electrical price. Abkenar et al [3] established multiple objective nonlinear optimizing models for a water diversion system, considering the cost and energy consumption of environmental contamination emissions, and determined optimization schemes by applying the genetic algorithm with continuous and discrete coding.…”

This article presents a methodology for optimizing the operation of parallel pumping stations in an open-channel water transfer system. A mathematical model was established for the minimum power with constraints on water level, flow rate and pump unit performance, and related factors. In the objective function, energy consumption of relevant equipment or facilities, such as main pump units, power transmission and transformation equipment, and auxiliary equipment, was considered comprehensively. The model was decomposed to two layers for solving. In the first layer, by using discharge distribution ratio as a variable, the flow rate and water level of the two water channels could be determined by employing the dichotomy approach (DA), and were calculated according to the principle of energy conservation, considering energy loss caused by hydraulic leakage and evaporation losses. In the second layer, the number of running pumps and the flow rate of a single pump were obtained by simulated annealing–particle swarm optimization (SA–PSO). The hybrid of the two algorithms is called the dichotomy approach–simulated annealing–particle swarm optimization (DA–SA–PSO). To verify the efficiency and validity of DA–SA–PSO, SA–PSO is also applied to determine discharge distribution ratio. The results indicate that the computation time using DA–SA–PSO is 1/30 of that using double-layer SA–PSO (dSA–PSO). Compared with the original plan, the optimal solution could result in power savings of 14–35%. Thus, the DA–SA–PSO is highly efficient for optimizing system operation in real time.

“…For the research on the optimization operation of variable working conditions, Feng Xiaoli et al [2] used the annealing genetic algorithm to study the optimization operation schemes of five different combinations of variable rotational speed and variable blade angles for Gaogang pumping station, which has significant effect on saving electricity compared with the existing operating scheme. Zhang Yuhong et al [3] studied the daily optimization by the adjustable-blade regulation of the cascade pumping station, and the result of optimization operation could reduce the daily operating cost by 23.77%.…”

The setting of regulation mode for operating condition has great influence on the reliability and economy of pump units. For typical pumping stations, different adjustment modes of pump unit were calculated considering optimization operation and the equipment investment. The rationality of the regulation mode was analyzed from the economic perspective for the existing condition of pumping stations. The results show that the current regulation mode with adjusting rotational speed by variable frequency is reasonable in pumping station A, which can save more than 1.8 million yuan in operating costs every year. However, the current regulation mode with adjusting pump blade angles is not economical in pumping station B. If it is changed to adjusting rotational speed by variable frequency, which will save about 1.9 million yuan in operating costs every year. The results are of guiding significance to the design and selection of pump unit and the regulation mode.
