Embodiment 1
[0029] figure 1 It is a flow chart of the wind turbine control method provided by Embodiment 1 of the present invention. The control method can be executed by a controller in the wind turbine control system, and can be implemented in the form of software and / or hardware. Such as figure 1 As shown, the wind turbine control method may include:
[0030] Step 101, the controller acquires the detected low temperature operating parameters;
[0031] Among them, the detected low-temperature operating parameters are obtained, and the low-temperature operating parameters are detected by a sensor connected to the controller. The sensor converts the detection signal into an electrical signal and provides it to the controller. The wind turbine controller recognizes the electrical signal and converts it into The digital signals are stored in registers of the controller. The low-temperature operation parameters may include: the temperature of the pitch motor, the oil temperature of the g...
Embodiment 2
[0039] figure 2 It is a flow chart of the method for judging low-temperature operating conditions in the wind turbine control method provided in Embodiment 2. This method can be executed by the controller in the wind turbine control system, and can be implemented in the form of software and / or hardware. This embodiment is based on the above embodiments, and further optimizes the process of judging the low temperature operating conditions. Such as figure 2 As shown, judging whether the low-temperature operation condition is met according to the detected low-temperature operation parameters may specifically include: judging whether at least one of the temperature of the pitch motor, the oil temperature of the gearbox, and the ambient temperature is lower than the respective set temperature, If yes, the low-temperature operation condition is satisfied, and if not, the low-temperature operation condition is not satisfied. Specific steps are as follows:
[0040] Step 10211, ju...
Embodiment 3
[0056] Figure 4 It is a flow chart of the low-temperature operation mode in the wind turbine control method provided by Embodiment 3 of the present invention. The method can be executed by the controller in the wind turbine control system, and can be implemented in the form of software and / or hardware. Based on the above-mentioned embodiments, this embodiment further optimizes the specific scheme of the low-temperature operation mode. Such as Figure 4 As shown, the low temperature operation mode includes: adjusting the blades of the wind turbine to the windward rotation state, after a set time, obtaining the normal temperature operation parameters, judging whether the normal temperature operation conditions are met, and if so, starting the normal temperature operation mode. Then the preferred scheme is as follows:
[0057] Step 1031, start the yaw system to adjust the impeller of the wind turbine to the windward position;
[0058] Get the detected current wind direction, ...
