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.

Key words
