全渠道控制系统在中卫南山台子扬水灌区的应用

The Application of Total Channel Control in Nanshantaizi Pumping Irrigation Area of Zhongwei

针对中卫南山台子扬水灌区缺乏调水控水和测量水设施,水资源利用率和灌溉保证率低等问题,应用测控一体化闸门和全渠道控制系统(Total Channel Control,TCC)作为其推广现代化灌溉系统的硬件及软件基础。TCC 3次试运行结果表明,系统控制的测控一体化闸门可以在短时间内响应南山台子扬水干渠渠系流量动态变化,自动调节到最佳工作状态,同时控制涉及渠段的水位波动在±0.05 m以内。分析表明,在中卫南山台子扬水灌区应用TCC将有效提高水资源利用率和灌溉保证率。

To solve the problems of the lack of water control and measurement facilities,low water use efficiency and irrigation guarantee ratein Nanshantaizi pumping irrigation area of Zhongwei,the integrated measurement and control gates and total channel control(TCC)system are applied as the hardware and software foundation to popularize modern irrigation system.The results of three TCC test runs indicate that the TCC controlled integrated gates can respond rapidly to the flow dynamic change in the main canal system,automatically adjust to the best working state.At the same time,the fluctuation range of water level in the canal section is controlled within 0.05 m.The analysis shows that,TCC will improve the water use efficiency and irrigation guarantee rate effectively.
