- 摘要:
- 为防止长距离重力流输水管道水锤发生,减少水锤危害,以山西省某市长距离重力流输水工程(输水管道长度为18.492 km,水位高差为84 m)为例,建立了水力瞬态计算模型,基于该模型采用遗传算法开发了关阀曲线及气阀布置方案的优化程序。分别对一~四阶段关阀曲线及气阀布置方案进行了优化计算,并对不同关阀方案下程序运行效率和水锤防护效果进行了对比分析。结果表明,多阶段关阀方案明显优于一阶段关阀方案;多阶段方案中,三阶段关阀方案的遗传算法优化成功率更高,对水锤的防护效果更好,气阀布置的数量明显减少。
- 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.
