The Study of the Penzhin Bay Tidal Energy Use Possibilities for Generating Electricity

Abstract

This article examines and deals with the experience of building tidal power plants in Russia and in the world, analyzes the possibilities of using tidal energy in the Penzhin Bay to solve the energy problems in Kamchatka region. The purpose of this work is to propose and explore a new implementation version of the Penzhin tidal power plant. The tidal power plants implemented projects analysis method revealed the advantages and disadvantages of various constructive and technological solutions, their construction conditions, which are taken into account in the proposed option were studied. The method of comparison with the Penzhin tidal power plant existing projects identified the main advantages of the proposed option. A variant which consists in the need to lay underground two conduits connecting the Penzhin Bay with the Pacific Ocean, was proposed for the construction of the Penzhin tidal power station. Near the Pacific Ocean, each conduit is divided into two siphons, in which horizontal bulb hydro-turbines are installed. It was investigated that the best place for generators installation is in the engine room of the power plant the head building, located on land. The shafts of the turbine and the generator are connected using a bevel gearing, which makes such a technical solution possible. The approximate power of turbines and generators was calculated; their brands were proposed. It was also calculated the volume of water required for the passage and during the tide. As a result, it was proved that this power plant will operate continuously, and water will always flow in one direction. The proposed option can be taken into consideration in the presence of similar geographical and technical conditions in other parts of the world. Power generation will allow for the realization of the Kamchatka region “breakthrough” plans in services, industry and agriculture.
