WIND-DRIVEN ELECTRIC PLANT Russian patent published in 1994 - IPC

FIELD: wind power engineering. SUBSTANCE: wind-driven electric plant has pickup 3 of rotational speed mechanically coupled to rotor of generator 2 which electrical input is connected to functional converter 4, adder 8 connected with its input to output of functional converter 4, power pickup 11 connected to second input of adder 8 and load 13, integrator 7 linked to output of adder 8, null detector 6, unit 12 for control over frequency converter which inputs are connected to output of integrator 7, controlled rectifier 5, unit 15 for automatic supply of gases, electrochemical generator 16, inverter 17, synchronization unit 18, frequency converter 14. One input of converter 14 is coupled to unit for control over frequency converter, second power input - to power output of A.C. generator 2 and output terminates in load 13. Input of synchronization unit 18 is connected to output of converter 14. One of inputs of inverter 17 is linked to synchronization unit 18, the other one is connected to electrochemical generator 16 and its power output is terminated in load 13. EFFECT: enhanced operational efficiency and reliability. 1 dwg
