METHOD OF POWER SUPPLY TO SUMMER MILKING SYSTEM FROM SMALL HYDRO-ELECTRIC STATION Russian patent published in 2012 - IPC F03B15/06 F03B13/00 A01J5/07 

FIELD: electricity.

SUBSTANCE: at the moment of small hydro-electric station start-up all stages of ballast load are started, when rated frequency of generator 2 rotation is achieved, an asynchronous electric motor of a water supply pump 5 is started with a device of reactive power compensation. At the same time the load is redistributed between the ballast load and the started asynchronous electric motor of the water supply pump 5 with the device of individual compensation of reactive power, therefore voltage at the generator 2 stator changes insignificantly. Then upon completion of a transition process, an electric motor of a vacuum pump 6 is started with a device of individual compensation of reactive power. Upon completion of the transition process, similarly electric motors of the first milk pump 7, the second milk pump 8 and a pump of a milk cooler 9 are started, which, due to low capacity in respect to a generator of the small hydro-electric station, slightly reduce voltage at its leads, and therefore electromagnet torque at all electric motors operating under load practically does not change.

EFFECT: higher efficiency of small hydro-electric station application and improved stability of operation of milking system process equipment.
