结合工程实际,在国内首次采用希尔伯特-黄(HHT)变换方法,对叠加短周期波动的取水泵房前池长周期水面波动过程线进行解析。基于核电取排水明渠布置方案,按照HHT变换方法对工程全部建成后各泵房前池的水面过程线进行分析。对于最终工程平面布置方案,在DBF水位及其对应可能最大台风浪工况下以及在设计高水位、100 a一遇波浪作用下,均满足泵房取水对水面波动的要求。HHT变换方法为今后更准确可靠地对核电厂址取水泵房前池水面波动过程线进行数据分析提供了重要参考作用。
According to the engineering practice, Hilbert-Huang (HHT) transformation method was first used in China to analyze the long-period water surface fluctuating process line of water intake pumping station with superimposed short-period fluctuation. Based on the layout of the diversion and drainage channels for nuclear power stations, the water surface course of each pumphouse front pond after completion of the project is analyzed in accordance with the HHT transformation method. For the final project layout, the DBF water level and its corresponding maximum possible typhoon wave conditions, as well as the design of high water level, a 100-a wave encounter, to meet the water pumping station on the water surface fluctuations. HHT transformation method provides an important reference for the future more accurate and reliable data analysis on the surface water fluctuation process line of the water intake pump station in nuclear power plant site.
