摘要： A wind turbine includes multiple blades, multiple Micro Inertial Measurement Units (MIMUs) for sensing parameter signals of the blades, and a control system. The control system includes a blade bending moment calculation unit, a blade bending moment error signal calculation unit, and a pitch angle compensation command calculation unit. The blade bending moment calculation unit is used for calculating blade bending moment values of the blades based at least on the sensed parameters. The blade bending moment error signal calculation unit is used for calculating blade bending moment error signals of the blades based on the calculated blade bending moment values of the blades and multiple blade bending moment commands. The pitch angle compensation command calculation unit is used for calculating pitch angle compensation commands of the blades based on the calculated blade bending moment error signals to adjust pitch angles of the blades respectively.

摘要： A fault location system for a distribution network is disclosed. The fault location system includes at least one sensor and a fault location evaluation apparatus. The at least one sensor is located on the distribution network, for sensing current and dividing the distribution network into at least two regions. The fault location evaluation apparatus includes a fault region determination unit for determining which one of the at least two regions is a fault region where a fault occurs therein by calculating the sensed current from the at least one sensor.

摘要： A wind turbine includes a rotor comprising multiple blades mounted on a hub, MIMUs mounted on each blade for sensing parameter signals thereof, and a control system. The control system includes a wind speed calculation unit, a wind shear calculation unit, a pitch angle compensation command calculation unit, and a pitch control unit. The wind speed calculation unit is used for calculating wind speeds at the blades based at least on the sensed parameter signals. The wind shear calculation unit is used for calculating a characteristic shear exponent based at least on the calculated wind speeds. The pitch angle compensation command calculation unit is used for calculating pitch angle compensation commands of the blades based at least on the calculated characteristic shear exponent. The pitch control unit is used for adjusting the pitch angles of the blades based on the calculated pitch angle compensation commands.
