    摘要: The disclosure details implementations of apparatuses, methods, and systems for regulating DC bus voltages. In an implementation, the system is configured to regulate the DC bus voltage directly by operating at the DC bus rather than indirectly on the AC side of the DC bus. In one implementation, the DC voltage regulator is configured with components including a DC voltage regulator power control board, a switching device, a resistor, and a flyback diode. In one non-limiting implementation example, the DC voltage regulator may be used to control the DC bus voltage of a doubly fed induction generator of a wind turbine. In this implementation, the DC voltage regulator effectively protects the converter of the induction generator and also reduces the transient torques on the generator shaft during voltage irregularities. This, in turn, reduces excessive wear on the wind turbine gearbox by limiting fatigue loads on the gear teeth that may result from transient torques.

    摘要: The present disclosure relates to a method for controlling a wind turbine of the type including a rotor, a generator, a frequency converter, a control unit and means for connecting to a wind farm grid, using means for receiving a local voltage reference value (VREF) and a regulator (1) which calculates the reactive power to be generated (QT) as a function of the voltage error (ΔV), such that it can be operated over the entire voltage range. The system also includes: at least one saturator element (2, 6, 7) in which the reactive power to be generated is limited, whereby the limits (Q—MAX, Q—MIN, QC—MAX, QC—MIN, QS—MAX, QS—MIN) are calculated dynamically as a function of the voltage, this block outputting a reference reactive power of the wind turbine (Q—REF, QC—REF, Qs—REF); and an element (3) for calculating the actual limit of the active power (PMAX) as a function of the pre-limited reactive power (Q—REF, Qs—REF) and the apparent power available at that moment.
