本文提出了一种全新的潮汐能开发方式,把封闭管道中的水击效应应用到潮汐能开发中。利用水锤泵将海水提至高水库,把潮汐能的低水头势能转化成高水头势能存蓄在高水库中,再视需求进行发电,免除了传统方法先潮汐发电再抽水蓄能的二次转化。本文通过模型泵测试模拟了水锤泵在潮差的驱动下将水提送到蓄水库的工作状况,获取了1.0~3.0 m水位差条件下,将水输送到5.0~20.0 m水头蓄水池时模型水锤泵的工作效率和输出功率。试验表明,在1.0~3.0 m水位差条件下,水锤泵的能量转化效率超过0.60,且水头变动时,效率基本稳定。经估算,水锤泵潮汐蓄能发电的平均能量利用率略高于潮汐发电联合抽水蓄能。
Abstract
We propose a new method for tidal energy utilization using water-hammer in pipeline. The hydro-ram can convert potential energy of low water head to higher head by pumping sea water to high reservoir,which avoid the energy conversion from tidal power to pumped storage. Model pump test was carried out to simulate the 1~3 m working condition of pumping sea water to 5~20 m high reservoir. We got the efficiency and output power of several supply head in the test. The experiment shows that the efficiency can be higher than 60% in the working condition and remain stable when water level changes.
