There are huge ocean and river resources in China, 1.5 meters of the annual mean wave height in the Huanghai Sea, the East Sea, 1 meter of the mean wave height at the South Sea, annual mean period of wave is 6 seconds, can estimate in view of the above, the coastal wave of China can be about 20～40 kilowatts every meter, and total energy reaches 1.7 hundred million kilowatts.The wave that the whole world had can be up to 2,500,000,000 kilowatts, close 3,000,000,000 kilowatts of the tidal energy that the whole world had.Energy by ocean current is exactly the energy that the river in the ocean produces.Except the dipping and heaving of fluctuation that tidewater is arranged and wave, some seawater often flows towards certain orientation in the vast oceans.Its blood just as flowing in the human body, caing be compared to again is the brook, great river that land Pentium, median year is flowing at great speed quietly in the ocean.The river of ocean current and land is the same, and certain length, width, the degree of depth and flow velocity are also arranged.Generally speaking, ocean current reaches several thousand kilometers, and is also longer than the Changjiang river, the Yellow River; And its width is more much bigger than general river, can be tens times even hundreds of times of the Changjiang river width; The speed of ocean current is generally per hour 1～2 nautical mile, and some can reach 4～5 nautical miles.The river energy of China also is very abundant, is example with the Changjiang river, and the mean flowrate of Yangtze River Water is 2150 cubic metres of per seconds, and the mean velocity of water is 2.5 meters of per seconds.The kinetic energy water stream power generation system can be installed in these rivers, the kinetic energy water stream power generation system does not need to build barrage, do not need the immigrant and flood the good farmland, as long as the place of flowing water is arranged in the river, just can build the kinetic energy waterflow power station, certainly the power of current is big more, sends out electric just manyly more, has short, advantage such as economic benefit is fast of construction works time.
The present invention utilizes the integration of physical geography key element fully, is the real natural renewable sources of energy, so the calculating of the production capacity of generating is different with traditional power station.Consume fire coal as coal-fired station, production capacity is calculated according to 60% left and right sides running rate of electric motor power.Production capacity of the present invention is according to the river, current, wave, morning and evening tides and ocean dynamically and wind and solar energy and deciding.Wind and solar energy of the present invention and current comprehensive system for electric generation are round-the-clock property, and efficient can reach 85-95%, are more than the twice of independent wind energy power and independent solar electrical energy generation.And wind and solar energy and kinetic energy current are power generation complemented, reduce the loss of power delivery.This advantage is even more important to river, wave, tidal power generation.Simple is the river that can be effectively applied under the different situations with having modular design, current, wave, morning and evening tides and ocean power generation.Increase or reduce several modules and will reduce operation and maintenance expense effectively.In addition, our water stream power generation system does not need dam, reservoir or other big civil engineerings, can reduce the public and environmetal impact, and significantly reduce early investment, is particularly suitable for using and promoting in developing country.
In addition, the common disadvantage of the existing various environmental friendly regenerated energy is that construction cost is very high, as traditional seawave power generation (9000 yuan/KW), nuclear power (13000 yuan/KW), wind-powered electricity generation (7500 yuan/KW), solar energy (10000 yuan/KW), liquefied petroleum gas (LPG) (6300 yuan/KW) etc., so be unfavorable for trade benefit.The present invention's cost of generating electricity is about 4800 yuan/KW, and (5000 yuan/KW) cost is close, has tangible competitive advantage with coal-fired thermal power generation.
The cost of production valency of the every degree electricity of kinetic energy current generating is cheap, main reason is the cost that the kinetic energy current renewable sources of energy do not have material loss, the maintenance of kinetic energy current and the supply of fluid oil are main loss, the maintenance expenses of the generator set in kinetic energy current power station is a standard, and often the piston and the filter screen of cleaning collection cylinder pressure inside are main maintenance work.On the other hand, our water stream power generation system can be directly installed on the resident center, from the big city to the suburb to the rural area.Be not only the zone that needs most electricity consumption, and can save the expense of transmission losses and electric wire, technology is safety also, is low cost and high efficient energy sources.Kinetic energy current generatings almost be full-time, annual do not have stop, continuous running makes effective productivity reach 90% at least, limited by natural condition unlike wind-force, solar energy etc., the number during production had only surplus in the of 2000 hour is more than the twice of wind energy power and solar electrical energy generation.
More than the combination system of current, sea wave as well as tide kinetic energy provided by the present invention and wind energy solar power is described in detail.Used specific case herein principle of the present invention and mode of execution are set forth, above embodiment's explanation just is used for helping to understand core concept of the present invention.Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention, can also carry out some improvement and modification to the present invention, these improvement and modification also fall in the protection domain of claim of the present invention.
