Wind powered direct drive water pumping systems
Wind turbine of comparatively large capacities are used exclusively for electricity generation, and so far small multiblade horizontal axis turbines are extensively employed for water pumping with reciprocating piston pumps. However, the advent of wind turbines for irrigation, characterised with large discharge volume pumps, require application of large capacity and efficient ones to make the operation viable. An analysis is made in this paper to find matching pump coupled directly with wind turbine for optimum system operation in variable speed. There exist various type of wind turbines, operating on different principles having characteristics different, dependent not only on the types but also on the design criteria of the individuals. Water pumps are also of various types whose operation characteristics vary with the type, mode of operation and design parameters. A nondimensional analysis is carried out to match the two, to operate at optimum, by superimposing the operating characteristics of the one over the other. The transmission method is also taken in account on the investment analysis of the whole system. Positive displacement pumps are best suited for high starting torque turbines e.g. Savonius or Filippini or multiblade horizontal axis rotors, and consequently are less efficient, though is advantageous for high water lift operation.
