| 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. |

THE EMBODIMENTS OF THE INVENTION
IN WHICH AN EXCLUSIVE PROPERTY OR PRIVILEGE IS
CLAIMED ARE DEFINED AS FOLLOWS:
1. A tidal power plant for lagoon comprising a head reservoir and an one-way power house; said one-way power house is detached from said head reservoir and is located on lagoon bed; said one-way power house generates power during ebb and flood with water delivered from said head reservoir; wherein said head reservoir is filled with lagoon water at end of flood. 2. A tidal power plant for lagoon of claim 1 comprising a tail reservoir; said tail reservoir is formed by the wall constructed around said power house; wherein said tail reservoir is emptied of water at end of ebb via vertical sluices located in said wall. 3. A tidal power plant for lagoon of claim 1 in which said head reservoir consists of several parts connected between themselves with water ways; wherein some of said parts are located on lagoon bed along lagoon shore edge. 4. A tidal power plant for lagoon of claim 1 comprising a flow distributor; said distributor is connected with said head reservoir with an open channel; said distributor is connected with said one-way power house with a common intake; wherein said common intake delivers water under pressure to said one-way power house turbines. 5. A tidal power plant for lagoon of claim 4 in which said flow distributor is formed of four side walls and a flat bottom and is open at the top; wherein one of said side walls facing lagoon shore has an opening for said open channel connecting said reservoir with said flow distributor; wherein one of said side walls facing lagoon has gates for water flow from lagoon filling via said channel said head reservoir during flood end; wherein said flat bottom has an opening for said common intake. 6. A tidal power plant for lagoon of claim 5 said one-way power house of which is equipped with bulb turbines, AC generators, and frequency converters. 7. A tidal power plant for lagoon of claim 2 comprising a flow distributor; said distributor is connected with said head reservoir with an open channel; said distributor is connected with said one-way power house with a common intake; wherein said common intake delivers water under pressure to said one-way power house turbines. 8. A tidal power plant for lagoon of claim 7 in which said flow distributor is formed of four side walls and a flat bottom and is open at the top; wherein one of said side walls facing lagoon shore has an opening for said open channel connecting said reservoir with said flow distributor; wherein one of said side walls facing lagoon has gates for water flow from lagoon filling via said channel said head reservoir during flood end; wherein said flat bottom has an opening for said common intake. 9. A tidal power plant for lagoon of claim 8 said one-way power house of which is equipped with bulb turbines, AC generators, and frequency converters. |
