Definitions

• the technical field of the invention relates to providing a method and apparatus for controlling the harnessing of renewable wind and water flow energy to a constant power value and constant frequency with a wind turbine or a marine hydrokinetic (MHK) river or a tidal or an ocean wave turbine or an ocean current turbine, and, more particularly, to the field of wind and water flow turbines which utilize a speed converter herein called a Hummingbird speed converter.
• MHK marine hydrokinetic
• a wind or water flow turbine for generating constant alternating current frequency electricity may comprise three components: a harnessing module, a controlling module and a generating module.
• a typical harnessing module comprises a wind propeller which turns a shaft of an electricity generator or a water flow or wave turbine which captures water flow energy that likewise turns the shaft of an alternating current electricity generator.
• Three known renewable energy harnessing modules are shown in Figures 5A-5C of U. S. Patent Application Ser. No. 16/701,741 filed December 3, 2019 entitled“Concentric Wing Turbines” of the same inventor and incorporated by reference into the present application in its entirety.
• a problem with known turbines is their inefficiency in obtaining a constant electric frequency such as 60 Hz (US) or 50 Hz (European) and their reliance on periods of variable wind and water flow. For example, water flows over a dam and there may be a drought requiring the turbines to shut down or there may not be sufficient wind to turn a propeller-driven turbine.
• an electrical power converter is used to produce a constant frequency electrical alternating current when the wind is blowing sufficiently. This power converter converts alternating current of variable frequency to direct current and then back to constant frequency alternating current electricity. This power conversion is very inefficient and, also, the electronics of the known power converter are known to fail.
• Hydroelectric and wind energy are two major sources of so-called renewable energy.
• 33.0% or one-third of all electric energy is produced by steam generation using coal.
• a third source of renewable energy comes from the sun (only 1.0%).
• a first renewable energy source comes from water (hydro amounts to 6.0% according to the E1A). Water flows at variable speed and so does wind; (ocean waves vary with the strength of winds over the ocean). The sun is only bright enough during daytime hours for conversion to electrical energy by known solar panels.
• An advantage of water flow over wind is the mass/density, inertia or power that may be generated by the flow of water compared with the flow of wind (wind amounts to 6.0% of generated electricity) where wind must be harnessed by large wind-driven propellers or rotor blades.
• river water typically flows at all hours of the day and night at a relatively constant rate of flow.
• Natural gas provides, in the same year, about 34.0% of U. S. electric energy, and nuclear energy now provides about 20.0%, for example, via steam turbine generation.
• Petroleum such as oil, is used to produce only about 1% of U. S. electric energy.
• Coal, natural gas, biomass (2.0%) and petroleum are carbon-based and when burned produce emissions which can be costly to mitigate or, if not mitigated, can be dangerous or at least increase the so-called carbon footprint in the earth’s atmosphere.
• the supply of coal, gas and petroleum is also limited. Nuclear energy generation, unless handled with extreme care, is dangerous, and the spent nuclear fuel becomes a hazard to the world.
• renewables include, but are not limited to, the air (wind power), the sun (solar power) and water (hydroelectric and marine hydrokinetic, MHK, energy via river or tidal and ocean wave and ocean current water turbine) sources.
• the Grand Coulee dam, Hoover dam and the Tennessee Valley Authority are exemplary of projects started in the early 20 th century in the United States for generating hydroelectric power, but these require large dams to build potential energy for turning electric turbine generators. Large hydroelectric generators in such dams on rivers in the United States are now being replaced with more efficient and larger capacity generators.
• dam-based hydroelectric power is limited, and the dams block migrating fish and commercial river traffic on navigable rivers.
• the dams back up a river to form a lake which can take away valuable land resources that could be used to grow food or permit animals to feed.
• the created lakes provide water control and recreational use for boating, fishing and the like.
• wind and water driven electricity generators and control that may save the cost of building a dam, permit the marine hydrokinetic (MHK) generation of electricity and use the high inertia flow of a river or tidal estuary flow of ocean currents and tides to produce constant power in comparison with wind.
• hydroelectric energy amounts to the next greatest renewable source at about 6.0%, it is believed that more can be done to efficiently utilize the rivers, ocean waves and tides and ocean currents in the United States and in developing nations, for example, in Africa than by hindering the flow of water commerce by the construction of dams.
• a mechanical meshed gear gearbox used in renewable energy systems is known to have a failure rate of approximately 5%.
• Electronics used in a wind turbine have the highest potential failure rate of 26%.
• Control units generally exhibit a failure rate of 11%.
• Sensors exhibit approximately a 10% failure rate.
• the failure rate of a variable frequency converter or variable power converter may be on the order of 26% failure rate (electronics) according to an ongoing consortium’s study of drive train dynamics at the University of Strathclyde, Glasgow, Scotland.
• the mean time between failures of a 1.5 megawatt wind turbine may be only two years on average (but the real failure rate is an industrial secret); and the replacement cost may be over $50,000 (for example, $50,000 to $100,000 US) per variable frequency to constant power converter.
• a failure rate of the variable speed generator of a known turbine is on the order of 4.5%. Consequently, problems related to known wind, water (river, ocean wave and tidal) turbines relate closely to the failure rate of gearboxes, generators, variable frequency converters dr variable power converters and associated electronics and inefficiencies of operation.
• a solution to the identified problems is to provide a constant rotational velocity as an input to the constant speed electric generator so that an electricity generator in turn can produce a constant alternating current frequency output and deliver a constant voltage and constant current (power) directly to an electric grid.
• Transmissions or speed converters for example, have been developed or are under development by the following entities: IQWind, Fallbrook and Voith Wind (Voith Turbo) to provide a constant output from a variable input.
• US Patent No. 7,081,689, (the‘689 patent) assigned to Voith Turbo of Germany is exemplary of an overall system control design providing three levels of generator control. Voith provides a so-called power split gear.
• a hydrodynamic Fottinger speed converter or transformer may be connected between a rotor and gear assembly and a synchronous generator may output power to a grid, for example, at 50 Hz (European).
• a recent development in the art of gearboxes is a magnetic gear which relies on permanent magnets and avoids meshed gears.
• Magnetic gears for example, developed by and available from Magnomatics, Sheffield, UK, have an air gap between sheath and shaft and so there is no meshing of gears in a gearbox. Alternating north and south poled permanent magnets may slip with a burst of water or wind energy with a magnetic gear that might break a meshed gear gearbox.
• a magnetic gear yields when a large burst of water/wind energy or a tidal or wave burst of water energy turns a gearbox input while a meshed gear may break or cause considerable wear to a meshed gear of the gearbox.
• Known marine hydrokinetic (MHK) turbines such as run-of-the-river, tidal, and hydrokinetic river turbines have problems. There is the problem of having to convert a harnessed variable rotational speed to a constant alternating current frequency and so provide a dependable constant power output.
• MHK marine hydrokinetic
• the density (mass or inertia) of water is much greater than that of wind and its speed is not as variable as wind speed especially when used in a relatively constant flowing river or steam which flows continuously in the same direction (such as the Mississippi River of the United States).
• Tides are reversible (high tide to low tide flowing toward the ocean and low tide to high tide flowing in from the ocean) and associated known turbines may be limited to generating power in one direction of water flow (during changing high to low tide or low to high tide) and generate maximum power at only low and high tides during a day.
• Resultant output power is sinusoidal in nature (water flowing in to a maximum and then reversing and flowing out to a maximum during a day/night high tide/low tide cycle).
• a concept for improving turbines is use of a direct drive in which a rotor and a shaft drive a generator.
• a direct drive may be used to directly drive an electric generator without using a gearbox, i.e. directly driving the generator.
• the failure and efficiency problems of gearboxes may be eliminated by eliminating the gearbox and substituting direct drive.
• One may increase the number of poles by fifty times, for example, use power converters or frequency converters and so result in reduced down time for gearbox repairs at the expense of increased cost due to the bigger generators.
• a speed converter to convert variable speed to constant speed is disclosed in U. S. Patent No. 8,388,481 of Kyung Soo Han, incorporated by reference as to its entire contents.
• the speed converter is entirely mechanical and so scalable and improves upon the high failure rate, reliability and efficiency of known electrical/mechanical systems.
• Speed converters under development are also frequency converters and are shown in this and other patent applications and patents of Kyung Soo Han and may be referred to as infinitely variable motion control devices (TVMC) and have named the principle“motionics” which may comprise speed converter gear assemblies such that rotational speed may be changed to a constant speed for driving an electricity generator at this constant rotational speed so that the generator produces a constant desired electrical frequency output.

• the apparatus may comprise a waterwheel and may comprise a gear and belt drive inside which may, because of the belt, be susceptible to slippage.
• a 15 kW waterfall turbine is described for use at a waterfall such as at spillways or outflows in industrial plants.
• Hydrovolts also produces a 12 kW zero-head canal turbine that allegedly can capture the energy in moving water.
• Hydrovolts’ rotating (hinged) blades may control some of the water flow speed, but it is urged that the exposed rotating blades may be susceptible to damage.
• a river turbine is known which may be attributed to Free Flow Power Corp. and may have been lowered to the bottom of the Mississippi River or attached to a piling. It is believed that such a device may be very similar to a turbine engine of an airplane but below water level and the water, at velocity, drives a turbine propeller (blades). Due to lowering prices of natural gas, the project became economically unviable (according to their press release in 2012).

• This small river turbine may comprise a turbine on a floating platform in a river having an underwater harnessing module that may come in sizes from five kilowatts to one hundred kilowatts in the future.
• An installation of a five kilowatt EnviroGen plant has been used by the First National communities on the Winnipeg River, requires no dams and may comprise a platform anchored in the river with an underwater harnessing module, for example, on the river bottom and the turbine may be located at another appropriate location.
• the plant may require no fuel, run twenty-four hours a day from river flow, and there may be no need for a large battery bank power back-up in dry spells.
• the underwater water energy harnessing module may comprise propellers or waterwheels that appear to be vertical to face the river water flow of approximately two meters per second at some locations or over three meters per second at other locations on the river.

• a map of the world shows the major rivers of the world, further highlighting the potential to harness water energy in rivers world-wide. (Predictable ocean tides cause water to flow upstream in ocean tributaries at low to high tide transitions and downstream in ocean tributaries at low tide and may be more widely used for electric power generation.)
• a typical hydroelectric power plant is mounted within a dam of a river.
• a first step in harnessing water energy is to build the dam to create a pressure head that is proportional to the depth of the water backed up by the dam.
• the backed-up water is represented by a reservoir or lake.
• At the base of the dam there may be intake gates which allow water that has been compressed by the head to flow at a predetermined flow rate through a penstock to a powerhouse which is one of many such powerhouses that may be constructed along the width of a large dam.
• One powerhouse may comprise a generator and a turbine which outputs electric power to long distance power lines. Once the water passes through the turbine, it is returned to the river downstream via a tailrace.

• the moveable rotor or stator may be moved axially toward one another to match a low value of torque/rpm so that the speed of the output shaft may increase with increasing wind or water flow and vice versa.
• This variable torque generator (VTG) process continues so as to maintain a relationship between speed of input (such as speed of wind or water flow (river/tide/ocean wave/ocean current) to match a desired rotational speed of output shaft and to maintain output shaft speed, for example, if used as an electric power generator, to produce, for example, more electricity (more current or amperes) of 60 Hz U. S. electric frequency or in Europe 50 Hz European frequency electric power.
• Differential Dynamics Corporation has also proposed a variable to constant speed generator including the concept of an infinitely variable torque generator, meaning that the one of the moveable rotor or the stator may be moved, for example, by a servo motor, not shown, to any position of proximity to or distance from one another or such that their respective magnetic flux fields are located far away from one another so as to not couple with one another, for example, to have an effect to cause a coupling of rotor and stator and a magnetic force field tending to cause the rotor to be stationary with the stator or move with the stator.
