In short, tidal power generation is to construct a water blocking dam at a gulf or a estuary with tides to form a reservoir, place a hydroelectric generating set in or beside the dam, and push the hydroelectric generating set to generate power when the seawater passes through a water turbine by utilizing the rising and falling of the seawater level during the fluctuation of the tides. Similar to the ordinary hydroelectric power generation principle, the tidal power generation stores seawater in a reservoir during tide rising through a water outlet reservoir, discharges seawater during tide falling, and drives a water turbine to rotate by utilizing the fall between high and low tide levels so as to drive a generator to generate power.
