WIND-DRIVEN POWER PLANT WITH AUXILIARY GENERATOR, AND PLANT OPERATION CONTROL METHOD Russian patent published in 2009 - IPC F02D7/02 

FIELD: power engineering.

SUBSTANCE: invention refers to wind power engineering, and can be used for electric power generation. Plant consists of rotor, generator for generating electrical power, at least one turning blade which is installed in supports and used for controlling the setting angle, and auxiliary generator 8 that, in rotation frequency range with reduced rotation frequency in comparison to normal operating mode, is made so that it can generate electric energy for rotor blade setting control device and for the drive used for controlling the rotor blade setting angle for continuous operating mode in rotation frequency range. Wind-driven power plant control method involves mode of operation at reduced rotation frequency in comparison to normal operating mode, wherein auxiliary generator generates electrical power, and control device that controls the rotor blade setting angle for continuous operation of auxiliary generator at reduced rotation frequency; at that at least one control device and at least one drive for controlling the rotor blade setting angle are supplied with power from auxiliary generator.

EFFECT: invention will provide, in case of voltage loss, emergency power supply reached at low cost.
