摘要
结合实际工程案例,对泵站水力模型建立及校核两个过程进行分析,总结了水力建模所需参数及参数获取方式,明确了校核过程所需监测数据,提出了模型关键校核步骤。校核后,该泵站稳态水力模型在4种工况下的模拟值偏差均低于5%,瞬态水力模型在2种工况下的模拟值偏差均低于3.5%。
Combined with the actual engineering cases,this paper analyzes the two processes of hydraulic model establishment and calibration of the pumping station,summarizes the parameters required for hydraulic modeling and the method of obtaining parameters,clarifies the monitoring data required for the verification process,and proposes the key verification steps of the model.After the verification,the simulated value deviation of the steady-state hydraulic model of the pump station is less than 5%under the four working conditions,and the deviation of the simulated value of the transient hydraulic model under the two working conditions is less than 3.5%.
