关于提高管网平差工作效率与准确度的几点思考

Thinking about Improving Efficiency and Accuracy of Pipe Network Adjustment

对管网平差的工作经验进行了总结,介绍了提高工作效率的几种方法(如软件应用、水源点的设置等),从管网基础资料的收集、水量分配与时变化系数的选择、管道及阀门摩阻系数的选择、校核参数之间的误差补偿、延时水力模拟与水龄计算等方面,对影响管网平差计算准确度的因素进行分析,并提出了相应的解决方法。

The work experience of pipe network adjustment was summarized. Several methods to improve the work efficiency, such as software application, setting of water source and so on were introduced. The factors influencing the accuracy of pipe network adjustment were analyzed in terms of collection of pipe network data, selection of water distribution coefficient and hourly variation coefficient, selection of specific friction coefficient of pipe and valve, error compensation between calibration parameters, extended hydraulic simulation and water age calculation. The corresponding solutions were put forward.
