Detailed Description
In order to make the technical problems solved, technical solutions adopted and technical effects achieved by the present invention clearer, the technical solutions of the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
Fig. 1 is a flowchart of a wind alignment method of a wind turbine generator according to this embodiment, where the wind turbine generator includes a yaw platform and a wind turbine generator, the yaw platform is used to adjust a yaw angle of the wind turbine generator, and a tower of the wind turbine generator is provided with an inclination angle sensor and an acceleration sensor, as shown in fig. 1, the wind alignment method of the wind turbine generator includes the following steps:
s1, detecting the inclination angle of the tower drum through an inclination angle sensor, and detecting the vibration main direction of the tower drum through an acceleration sensor;
s2, judging the current wind direction according to the inclination angle and/or the vibration main direction of the tower;
s3, calculating a target yaw angle of the yaw platform under the current wind direction;
s4, acquiring the current yaw angle of the yaw platform;
and S5, judging whether the current yaw angle of the yaw platform is consistent with the target yaw angle, if so, not adjusting the current yaw angle of the yaw platform, and if not, adjusting the current yaw angle of the yaw platform according to the target yaw angle.
Accurate wind direction needs to be determined when yaw is applied to wind, and when the wind acts on blades of the wind driven generator, the top of the tower barrel is stressed to generate inclination and vibration. When the wind direction and the wind speed are stable (in a steady state), the tower barrel is subjected to approximately constant wind force, the tower barrel is stressed and deformed, the top of the tower barrel is displaced, and the inclination direction is related to the wind direction. When the wind direction and the wind speed are unstable (in an unsteady state), the tower barrel vibrates under the operation of alternating wind, and in addition, the tower barrel is also subjected to vibration generated by the interaction of components of the wind driven generator, such as a blade, a cabin and the like, and the main direction of the vibration is related to the wind direction.
After the accurate wind direction is judged, the yaw system adjusts the position of the blades of the wind driven generator according to the target yaw angle calculated under the current wind direction, and the current yaw angle is closed to the target yaw angle, so that the blade surface of the wind wheel is always perpendicular to the incoming wind direction, the wind energy is utilized by the blades of the wind wheel to the maximum, and the wind alignment of the wind driven generator is realized.
The wind turbine generator wind alignment method provided by the embodiment only needs to provide each wind turbine generator with a plurality of acceleration sensors and inclination sensors, the investment cost is low, the practical popularization value is achieved, the wind direction is measured by utilizing working data (vibration and inclination), a complex algorithm is avoided, the application reliability is high, the generalization performance is strong, the wind direction identification is carried out in real time, the hysteresis of yaw adjustment caused by complex processing of data is avoided, the wind turbine generator wind alignment optimization with high precision, high efficiency, real-time performance and high reliability is realized, the occurrence of severe vibration and shutdown events caused by inaccurate wind alignment of the wind turbine generator can be effectively reduced, the efficiency of the wind turbine generator is improved, the operation safety of the wind turbine generator is guaranteed, and considerable economic benefits are brought to a wind field.
Due to the particularity of the operation space of the wind driven generator, the tower barrel only inclines in two directions, the inclination angle sensor can adopt a double-shaft inclination angle sensor, and further, when the wind direction and the wind speed are stable, the inclination angle components of the tower barrel projected on an x axis and a y axis are detected through the inclination angle sensor, the inclination angle of the tower barrel is calculated, and therefore the wind direction of the tower barrel under the comprehensive action of the wind force and the axial stress of the blades of the wind driven generator is judged. The tilt sensor is used for various applications for measuring angles, and can directly output tilt data such as angles. When the tilt sensor is stationary, i.e. no acceleration is applied in the lateral and vertical directions, only the gravitational acceleration is applied to it, and the angle between the vertical axis of gravity and the sensitive axis of the acceleration sensor is the measured tilt angle.
Further, when the wind direction and the wind speed change in real time, the acceleration sensors are used for detecting the acceleration components of the tower drum projected on the x axis and the y axis, and the vibration main direction of the tower drum is synthesized according to the vector synthesis method. The wind direction of the tower, the wind power generator blade and the engine room corresponding to the main vibration direction under the variable wind action and the interaction of all the components can be obtained according to a vector synthesis method. The acceleration sensor may be integrated with the tilt sensor on a circuit board. An acceleration sensor is a sensor capable of measuring acceleration, and generally comprises a mass, a damper, an elastic element, a sensing element, an adjusting circuit and the like. The acceleration sensor measures the inertia force borne by the mass block in the acceleration process, and obtains an acceleration value by utilizing a Newton's second law. The acceleration sensor can adopt a three-axis acceleration sensor, but due to the particularity of the operation space of the wind driven generator, the tower barrel only inclines in two directions, and the measurement data of two axes of the x axis and the y axis can be only adopted. The acceleration sensor can be a piezoelectric acceleration sensor, and the principle of the piezoelectric acceleration sensor is that the piezoelectric effect of piezoelectric ceramics or quartz crystals is utilized, and when the accelerometer is vibrated, the force of a mass block on a piezoelectric element is changed along with the change of the force. When the measured vibration frequency is much lower than the natural frequency of the accelerometer, then the force change is directly proportional to the measured acceleration.
In order to avoid instability of the wind turbine generator caused by frequent response, further, if the current yaw angle and the target yaw angle of the yaw platform are the same or within a preset error range, the current yaw angle and the target yaw angle of the yaw platform are judged to be consistent. The preset error range can be selected from a range of 0-1 degrees according to the wind power generation operation requirement and the environment characteristics.
In addition, no matter whether the wind driven generator is in a steady state or an unsteady state, once the measured deflection direction of the wind driven generator has no component in the direction of the rotor plane, the wind driven generator can be judged to be in no need of yaw correction. Thereby, the wind driven generator yaw can be qualitatively analyzed without quantitative analysis.
The anemoscope measures the wind direction in the interval of 3m/s-8m/s of the actual wind speed, measures that the wind direction has about 8 degrees of deviation, and according to the relation between the loss rate eta of the generated energy and the yaw error angle beta: η ═ 1-cos3 β × 100%. The wind deviation measured by the wind direction indicator of the wind driven generator can be calculated to cause 2.2% of power generation loss amount to the generator set. According to the loss rate of the generated power, assuming that the wind driven generator generates power for 24 hours, the power generation utilization coefficient is 0.75, and the wind driven generator with 2.1MW generates power in one day: 2.1 × 24 × 0.75 ═ 37.8MWh ═ 37800 kWh. Then, the wind direction is accurately measured by adopting the wind turbine generator set wind alignment method (the accuracy can reach 0.01 degrees), and the generated energy can be improved every day: 37800 × 2.2% ═ 831.6 kWh. According to the price of the commercial power, the price of electricity per degree (1 degree electricity is 1kWh) is about 0.56-0.62 yuan, and by adopting the wind turbine generator wind-facing method, one wind turbine generator can increase the income (lowest): 831.6 0.56 365 169979.04 membered.
The wind turbine generator wind aligning method provided by the embodiment has the following advantages:
(1) the cost is low: the implementation of the scheme only needs to provide an acceleration sensor and an inclination sensor for the wind driven generator, so that the cost is low, the practicability is high, and the popularization is easy;
(2) strong generalization ability: the yaw angle of the wind driven generator is associated by using vibration and inclination angle data, then wind direction identification is realized, a complex algorithm principle is not needed, the problem of generalization caused by the application of the algorithm to wind driven generators of different types is not needed, and the generalization capability is strong;
(3) the real-time performance is strong: the wind direction identification is directly carried out by using the data acquired by the sensor, so that the hysteresis of wind direction judgment caused by complex processing of an algorithm is avoided;
(4) the applicability is strong: the wind direction is identified by using the working data collected by the sensor, the wind direction is not easily influenced by severe environment, and the wind direction forecasting method has more practical applicability compared with a method for forecasting the wind direction by using big data by using a yaw angle of the wind driven generator as reference.
