The invention is tidal power plant for lagoon. It has two versions. The first version of the invention has a head reservoir located on the lagoon shore, a power house separately located on the lagoon bed, a flow distributor delivering the water front the head reservoir to the power house turbines during power generation and at the end of flood delivering the water from lagoon to the head reservoir to fill it up. The second version of the invention is different front the first one by the presence of the tail reservoir. In tins version the power house is located inside the tail reservoir. The cylindrical wall surrounding the tail reservoir keeps the water level in it significantly lower than the water level in lagoon during the power generation. This cylindrical wall has vertical sluices emptying the tail reservoir at the end of ebb. Due to the fact that the construction cost of the first version of invention is much smaller than of artificial basin in well known Inazin design it can have for much smaller cost the larger area. As the result with the same power equipment it annually generates on 45% more energy than Inazin design. The construction cost of the second version is higher titan the first if they have the same power equipment, however due to the higher head during power generation the second version annually generates on 30% more than the first version. |
