METHOD OF AND SYSTEM FOR CONVERTING MECHANICAL ENERGY OF WINDWHEEL INTO ELECTRIC ENERGY OF STORAGE BATTERY Russian patent published in 2004 - IPC

FIELD: power engineering.

SUBSTANCE: invention relates to self-contained power supply systems using renewable types of energy (wind, water, ebb and flow) with use of primary motors in which realization of conditions of maximum supply of energy requires changes of speed in wide limits. According to proposed method, electromotive force of storage battery is taken somewhat lower than rectified electromotive force of non-controllable rectifier under maximum velocity of windwheel and maximum field current of generator. Storage battery charging current is regulated by means of step-up direct current pulse converter according to law of maximum of power taken off windwheel, and generator field current is regulated according to law of maximum of windwheel system efficiency. To take off maximum energy from windwheel, generator rotational speed is set depending on wind velocity, and maximum efficiency of system is provided owing to regulation of generator field current as a function of generator speed. Proposed method is implemented in corresponding system.

EFFECT: minimization of installed power of electrical equipment, increased efficiency of energy conversion system and reliability.
