FIELD: turbines or turbomachines.
SUBSTANCE: group of inventions relates to wind turbine blade inclination angle adjustment system, to its control method and to wind turbine system. System 100 comprises power supply 102, controller 106 for receiving signal from source 102 and supplying control commands to inclination angle adjustment engine 32, and an ejection suppression device 104, comprising a switching element for monitoring input voltage coming from the network and controlling operation of the switching element, at least in part based on the controlled input voltage, so that the switching element blocks the current flowing through it to controller 106 when the controlled input voltage exceeds the voltage threshold. System also comprises shunting contactor 114 connected to source 102, and dynamic braking resistor configured to suppress voltage, coming from network, at least partially based on operation of contactor 114 and device 104.
EFFECT: group of inventions is aimed at control of wind turbine blade inclination angle adjustment system.
