摘要
在对给水管网进行水力模拟时,要求测压点测得的压力具有代表性.提出了用图论理论对给水管网测压点进行优化布置的方法,并编制算法程序,对某市实际管网进行布置后,区域内测压点与其它节点压差最大为4.43 m,比原来12.05 m减少7.62 m.结果表明该方法布置的测压点代表性强,该方法精度较高,比较适用.
The pressure measurement node in water distribution network should be representative node which used to provide data as parameter in water distribution network hydraulic model. Pressure measurement node layout problem on water distribution network could be solved by graph theory. Computer program was made and the algorithm was applicable. It is applied to water distribution network in a city; the result is that the maximum water pressure difference decreases from 12.05 m to 4.43 m. It is proved that the algorithm is very precise and applicable.
