摘要

Multiscale collaborative regulation of water transfer projects can achieve regulation goals that combine macro control with local adjustment, enhancing the resilience of regulation schemes. However, the implementation of multiscale collaborative regulation technology for water transfer projects remains challenging because of the strong uncertainty of the annual water demand process and difficulty in effectively coupling water quantity regulation models with hydraulic control models at various scales. This study considers the Jiaodong Water Transfer Project and its typical open canal section as an example; constructs water regulation models of long-, short-, and real-time scales; and proposes a technical chain of “total quantity control-coupled nesting-dynamic correction” to achieve multiscale collaborative regulation. The execution accuracy of the multiscale regulation schemes exceeds 99.85%.
