Abstract: The multi-mode electronic wind turbine control system establishes a reference blade angle for a two-bladed, horizontal axis, variable pitch wind turbine rotor. The blade angle is regulated by a hydraulic pitch change mechanism. The rotor is coupled to a sync. generator. The control system provides closed loop pitch control for rotor acceleration/deceleration speed and power. A single control integrator is used for all closed loop operating modes, with a rate limiter circuit in front of the control integrator to prevent integrator over-travel.
