摘　　要：本文提出基于蓄量控制的渠系运行规则,采用流量前馈和水位反馈的闸门组合控制,建立多渠段串联控制运行模型。应用该模型在ASCE推荐的缓坡测试渠道上进行了计算机仿真。结果表明,渠道系统能通过对渠池内的水量的调节进行合理调控以满足下游需水流量,不要求渠池水深保持不变,使渠系具有良好的响应和恢复特性。该渠道运行控制模型可用于具有复杂运行要求且缺少调节水库的大型渠道输水系统。An operation mode of canal system based on storage water volume control method is proposed. The principle of combining feedforward of discharge with feedback of water level is adopted for operation of gates and the operation model for multiple serial channel sections is established. The model is applied to simulate the operation process of the testing canal system proposed by ASCE. The simulation result shows that by reasonably regulating the pounding water volume in canal sections the necessary discharge for downstream of the canal system can be fulfilled. The canal system possesses good performance of response and resumption.
