增压泵组的节能优化研究
Research on Energy-saving Optimization of Parallel Pumping System
摘要
Abstract
This paper is aimed at the realization method and control logic of variable-pressure and energy-saving water supply strategy for parallel pumps by theoretical and experimental research. The PLC, combined with frequency converters, has been used as control-system of the new control strategy. In addition, the intelligent variable-pressure control was realized by modeling water demand estimation for piping system, variable-pressure control and the pump increased or decreased control, based on energy-efficiency condition. Suggested by the experiment results, the water demand estimation model is reliable with high sensibility and accuracy up to 90%. Besides, the control effect and energy-efficiency of pumps are improved effectively owing to the optimization control strategy. The obtained results can be referred by both the energy-saving optimization of parallel pumping system and the development of variable-pressure water supply mode.关键词
