Abstract:
This paper established a hydraulic transient calculation model to develop the optimization program of valve?closing curve and air valve layout scheme by using genetic algorithm in a long-distance gravity flow water delivery project in a city of Shanxi Province, so as to prevent the occurrence of water hammer and reduce its harm. The length of water pipeline was 18.492 km, and the height difference of water level was 84 m. The one-stage, two-stage, three-stage and four-stage valve-closing curve and the air valve layout scheme were optimized respectively, and the program efficiency and water hammer prevention performance under different valve-closing schemes were compared. The multi-stage valve-closing scheme was obviously better than the one-stage valve-closing scheme. Among the multi-stage valve-closing schemes, the genetic algorithm optimization success rate of the three-stage valve-closing scheme was higher, demonstrated better water hammer prevention performance, and significantly reduced the number of air valve.
