摘要 为了研究渠道运行控制中渠系建筑物的前馈控制时间,综合考虑上游调控及分水口调控对下游水量的影响,采用水量恒定方法,构建了渠道前馈控制时间计算模型,并将模型应用于山西省夹马口灌区.结果表明:模型所采用的流量拟合方程及参数对流量的拟合精度较高,能够有效表达下游流量在渠道调控下的变化情况,当采用该模型计算的调控时间进行控制时,可以基本保证流向下游的总水量恒定,水量偏差为0.8 m3.利用模型进一步分析了不同流量下的调控时间,发现随着流量的增大,分水口最优调控时间逐渐减小,在此基础上得到了流量-前馈控制时间、水深-前馈控制时间的线性拟合公式,为夹马口灌区渠道运行控制提供了参考.

Abstract: In order to study feedforward control time of canal buildings during canal operation, influences of upstream and outlet regulations on downstream water volume were considered. A constant water volume method was used to establish a canal feedforward control time computational model, and the model was applied to Jiamakou Irrigation District in Shanxi Province.The results showed that the flow rate fitting equations and parameters used in the model had high accuracy, and could effectively express the changes in downstream flow rate under the regulation of the canal.When the control time calculated by the model is used to control the canal, the total volume of water flowing downstream is roughly kept constant with a deviation of 0.8 m3only.The model was used to further analyze the regulation time at different flow rates. It was showed that the optimal outlet regulation time was decreased gradually with increasing flow rate.On this basis, the linear fitting formulas of flow rate and depth in terms of feedforward control time were obtained. They provide a reference for the operation control of Jiamakou Irrigation District.
