The invention discloses a cascaded pump station water conveying system optimized running-control coupling and coordinating method and system. The method comprises the steps of building a cascaded pump station water conveying system optimized running model, and solving a cascaded pump station water conveying system optimized running scheme; building a storage capacity compensation based pre-pumping water level control module by taking the water conveying flow and a corresponding water surface line in the optimized running scheme as control objectives, and fabricating each pump station control scheme; building a cascaded pump station water conveying system optimized running-control coupling model based on the optimized running model and the storage capacity compensation based pre-pumping water level control model; building a cascaded pump station water conveying running-control scheme evaluation model; building a cascaded pump station water conveying system optimized running-control coupling and coordinating model; and acquiring an optimized running scheme and a corresponding control scheme through coupling and solving the coupling and coordinating model. The method and the system disclosed by the invention provide technical support for optimized running and control of similar cascaded pump station water conveying systems in China such as an eastern route of the south-to-north water transfer project, the water conveying efficiency is improved, and the water conveying cost is reduced.

Description

technical field [0001] The invention belongs to the field of engineering operation optimization and automatic control, and relates to an optimal operation-control coupling coordination method and system for a cascade pumping station water delivery system. Background technique [0002] In recent years, a number of long-distance, cross-basin large-scale series and parallel cascade pumping station water delivery projects have been built both at home and abroad. Such as the Wanjiazhai Yellow River Diversion Project, the Jiaodong Water Diversion Project, and the East Route Project of the South-to-North Water Diversion Project. The total installed capacity and energy consumption of this type of project are large, and the corresponding energy-saving potential is huge; the cascades (pipes) are mostly rigid and semi-rigid in series, with small storage capacity and difficult operation and control. The optimal scheduling of such projects will create considerable economic benefits. Ho...
