多时间尺度自适应流域水量调控模型

Multi-time scale adaptive regulation model of a river basin water allocation

水量调控是解决流域水资源时空分布不均、防止河道断流的有效途径之一。在分析水量调控系统的基础上,建立了年、月、旬自适应水量调度模型框架。采用自适应控制理论和“总量控制、轨迹跟踪和滚动修正”的方法,建立了多尺度、多用户复杂条件下的流域水量调度模型。以黄河流域2003—2004调度年为例,按照中国国务院分水控制指标,分析年、月、旬3个时间尺度的水量调控过程和实例。结果显示,通过自适应多尺度滚动修正,能够保证调度目标的实现。模型具有可操作性和普适性强的特点。

A multi-time scale adaptive model was developed to control and regulate a river basin water allocation for the Yellow River Available Water Regulation Scheme. The model includes a river basin water allocation, a reservoir operation, and a flow routing which simulates the flow process and identifies system parameters. The model has been used for control and regulation decision-making through an analysis of the Yellow River in 2003-2004 to provide water allocation, runoff control, and coordinated reservoir operation based on preventing dry up and ice hazards and reservoir operation rules. The model can be applied for temporal and spatial water allocation among competitively users in a river basin.
