A new type of mar motrices power stations
The production of energy by the force of tides in Russia is still anecdotal. But the specialists expect a considerable progress in this domain and lay the foundations for future developments. The managing director of the SARL " Nova a Energ tika [New Energ tique], Victor Liatkh re, offers a new approach of the conception of power stations with mar motrice energy. Idea is not to block the gulf entirely by a power station, but instal him on the part where the speed of the currents of tides is the strongest.
The power station is made up of machines floating or fixed on the bottom, converting the energy of tides into electrical power or, when this is impossible or not profitable, by escorting energy by some liquid or gaseous hydrogen. The regulating of the hydraulic resistance of turbines allows to attain a maximum production. In general the power of the installation depends only on financial capacities of the investor, but she remains limited by a value depending on hydrologic and topographical parametres. That is why the use of mar motrice force does not require to block the basin on all its length and to create a pressure head.
The turbine patented by M Liatkh re, can be of size and output important. It has one or several pairs of floors turning in compared senses, what diminishes the mechanical load acting on the turbine.
The installation does not have an influence on its environment. The distance between its pales is big and their speed is weak, barely 2 - 3 times the speed of current, what does not fluster aquatic fauna. The installation can be towed, have gone up and be easily disassembled.
According to estimates, the optimum power of unit all these machines can attain 20 - 75 MW or even more, on a d troit between a basin and the sea, where speed is sizeable (2 - 4 m/s). Such speed of current meets to several place in Russia, on the European seas, etc. Certainly, the power of turbines varies according to time, but the use in network of several installations spaced out they some of others allows to slick the production of energy.
The building of power stations with mar motrice energy would allow to change qualitatively the energy card of Russia. A simple power station of new generation, installed in sea of Okhotsk in the bay of P njina could attain 165 GW and give about 312 TW.H over one year, is 30 % current Russian electrical complete productions.
According to M Liatkh re, the putting into service of electrical stations of offered type does not complain a lot of time and does not cause ecological problems. This task can and must, with a minimum of risks, be begun without delay.
