Abstract

In the near future, environmentally friendly compressed air will be able to contribute to the supply of mechanical propulsion energy in non-grid areas, especially in emerging markets (NIC). The "Enhanced Oil Recovery (EOR)" method of increasing the yield of oil wells requires compressing large quantities of CO2. For small wind turbines is in the lower power range for cost reasons i. a. to a mechanical or hydraulic adjustment of the rotor blade angle (pitch) to the current wind speed omitted. In the case of a compressor driven by the wind turbine, this would mean that the former would usually operate outside of the aerodynamically optimal speed / torque range or only start at higher wind speeds. In order to operate a gas-compacting wind turbine always in the aerodynamically optimal speed range, its load must be adapted to the currently available wind speed. Technology for driving compressors with wind wheels. In the invention, instead of the variable pitch, a power variable compressor is preferably used according to the swash plate principle. This type of compressor is controllable by means of a clocking solenoid valve in the power by the position of the swash plate is determined by the pressure difference between the output pressure and the pressure in the crankcase. This controllability can be utilized for a method for adjusting the load torque, which is realized in a control unit with a computer program.

Description

  • In the near future will be environmentally friendly compressed air (see DE 20 2013 101 251 and www.windcompressor.com ) can contribute to the supply of mechanical propulsion energy in areas without electricity supply, especially in emerging markets (NIC).
  • For the process of "Enhanced Oil Recovery (EOR)" to increase the yield of oil wells, large quantities of CO 2 must be compressed.
  • The instantaneous power of a wind turbine is determined by the aerodynamic "power coefficient" apart from the instantaneous wind speed (see Wikipedia). This is due to the design and depends on the "high speed number" of the wind turbine (see diagram below http://de.wikipedia.org/w/index.php?title=Datei:Schnelllaufzahl.png&filetimestamp=20130824161306& ). The high-speed number is mathematically linked to the rotor blade angle. In order to keep the power coefficient always maximum, or to achieve the necessary for three-phase generators fixed speed, therefore, the rotor blade angle is adjusted depending on the current wind speed in larger wind turbines.
  • Wind turbines for compressed air generation have long been known, for. Eg RP536663, DE3613871 . DE3628651 . WO2010 / 054844 . DE 11 2011 102 005 . DE 20 2011 105 711 . DE 10 2011 112 280 etc. However, such systems have not been enforced for the following reasons:
    • 1. Consider previous concepts with the exception of DE3613871 not the wind-driven fluctuating mechanical drive power for the compressor or its adverse effect on the wind turbine.
    • 2. The use in particular of highly compressed air as an intermediate storage medium for the time-shifted conversion into electrical energy is not cost-effective for reasons of expense, since in addition to the expansion of the highly compressed gas still heat must be supplied, see, for. B. DE 20 2014 002 179 ,
    • 3. For direct local use of industrial compressed air up to 10 bar z. For example, in workshops or factories, although no heat must be explicitly supplied, but in the highly industrialized countries with existing power grid, the compressed air generation by means of electrically driven compressor is more economical.
    • 4. On large company premises z. B. in Germany are indeed quite compressed air networks available, but not national.
    • 5. A transport in pressure vessels via truck as a substitute for a compressed air network, as it corresponds to highly compressed compressed air prior art, is not profitable at the above industrial pressures up to 10 bar because of the large volumes required.
  • Under small wind turbines are understood in the following wind turbines between 0.1 kW and 200 kW rated power. For the exact conceptual definition see DE 20 2011 105 711 ,
  • For small wind turbines is in the lower power range for cost reasons i. a. to a mechanical or hydraulic adjustment of the rotor blade angle (pitch) to the current wind speed omitted. In the case of a compressor driven by the wind turbine, this would mean that the former would usually operate outside of the aerodynamically optimal speed / torque range or only start at higher wind speeds.
  • In the invention, instead of the variable pitch, a power variable compressor ( 4 ) preferably used according to the swash plate principle, as it is known inter alia from the automotive industry, see, for. B. DE19847159 , This compressor type is controllable in particular in refrigerant compressors by means of a clocking solenoid valve in the power by the position of the swash plate is determined by the pressure difference between the output pressure and the pressure in the crankcase, see DE10331851 , This controllability can z. B. be used for procedures for adjusting the load torque, see, for. B. DE 10 2012 216 559 ,
  • To a gas-compacting wind turbine ( 1 ) can always operate in the aerodynamically optimal speed range, its load must be adjusted to the currently available wind speed. This is done according to the invention by a control unit ( 12 ) for the compressor ( 4 ) with microprocessor ( 13 ) and a computer program ( 14 ).
  • The computer program ( 14 ) operates according to the invention according to a variant of the known method of photovoltaic inverters "maximum peak power tracker" [MPPT, see, for. B. Lucien Roten, "Power Supply for a Wireless Sensor", thesis Hes. so, CH-1950 Sitten-2 (www.hevs.ch), 2010 ] by changing the power of the compressor ( 4 ), ie the associated load on the wind turbine ( 1 ) sets so that the latter each operates in the aerodynamically optimal operating point.
