摘要:
The present invention relates to a method of controlling a temperature of a component (101) of a wind turbine. The method comprises defining a set point temperature (Tc,set) of the component (101) of the wind turbine, determining the actual temperature (Tc) of the component (101) and comparing the defined set point temperature (Tc,set) and the determined actual temperature (Tc). Moreover the method comprises controlling the actual temperature (Tc) of the component (101) by controlling the output power (P) of the wind turbine based on the result of comparing the defined set point temperature (Tc,set) and the determined actual temperature (Tc).

A thermally responsive valve assembly (134) for scroll motor-compressor high temperature protection, which causes a high-side to low-side leak when excessive discharge gas temperatures are encountered, thereby causing the motor protector (35) to trip and de-energize the motor. The valve assembly (134) includes means for ducting (200) the excessive temperature discharge gas to the lower portion of the motor/compressor shell (10) to the motor to circulate the high temperature gas throughout the motor cavity. The excessive temperature discharge gas heats the motor stator (20) and windings (32) which will in turn cause the motor protector (35) to trip and de-energize the motor.

The present invention relates to a method and control system comprising at least one cable temperature sensor for measuring cable temperature values for at least one power collection cable (50, 55) connected to a wind turbine (20) and a controller (110) arranged to generate and output an overrating control signal to the wind turbine (20). The output overrating control signal sets an amount by which the power output of the wind turbine (20) is to be overrated. It is determined whether the measured cable temperature values exceed a temperature set point and modifying the overrating control signal to reduce the amount of overrating if the temperature set point is exceeded.

Wind turbine systems 100 and methods for operating wind turbine systems 100 are provided. In one embodiment, a method includes gating on a dynamic brake switch 184 of a dynamic brake 180 in a wind turbine power converter 130 when an experienced direct current (DC) bus voltage 202 is equal to or greater than a threshold DC bus voltage 204. The method further includes disabling a threshold temperature rating 222 for the dynamic brake switch 184 when the dynamic brake switch 184 is gated on, and gating off the dynamic brake switch 184 when the experienced DC bus voltage 202 is less than the threshold DC bus voltage 204.

An apparatus for controlling a wind power generator unit includes a deviation detection unit (100) to detect an angular deviation between windward and a current rotation direction of a nacelle (2) after a wind power generator is installed so as to face the windward, and a control unit (200) to receive data detected by the deviation detection unit (100) and to control a brake state and a yawing state of a yaw brake unit (50), wherein when the nacelle (2) rotates out of a preset deviation range, the control unit (100) temporarily releases frictional force of a brake pad (20) coming into close contact with a disk (10) so as to control a brake operation state of the yaw brake unit (50).
摘要:
A method of controlling a wind turbine is described. The method involves forecasting the temperature evolution of a component of the wind turbine based upon the current operating parameters of the wind turbine and upon a required power output; predicting from the temperature forecast a future alarm event caused by the temperature of the component exceeding a first threshold level or falling below a second threshold level; and adjusting the operating parameters of the wind turbine to control the temperature evolution of the component thereby to avoid or delay the predicted alarm event.
摘要:
Systems and methods for maintaining the active power production of a fluid turbine and regulating the temperature of an electrical generating component by controlling the reactive power production are disclosed. A thermal parameter of the electrical generating component is monitored. If the electrical generating component exceeds a thermal parameter the reactive power production of the turbine is reduced. A fluid turbine may be de-rated to further reduce an electrical generating component's thermal parameter. A fluid turbine may shut down to further reduce an electrical generating component's thermal parameter. A fluid turbine's power production is re-started when the electrical generating component returns to an acceptable thermal parameter.
