Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic equipment, and in particular to a photovoltaic support wind protection control method, a photovoltaic support wind protection control device, an electronic device and a storage medium. Background Art

[0002] In order to maximize the use of sunlight for photovoltaic power generation, adjustable dual-axis rotating photovoltaic brackets are widely used in the field of photovoltaic power generation. The dual-axis rotating photovoltaic bracket can adjust its own inclination and direction angle in real time to keep the photovoltaic components always perpendicular to the direct direction of sunlight, so as to obtain maximum power generation power in real time.

[0003] When encountering strong winds and bad weather, the surface of the photovoltaic modules is subjected to greater wind pressure, and the dual-axis rotating photovoltaic bracket can adjust its own angle to avoid damage. Most existing control schemes directly retract the photovoltaic modules when the external weather reaches a certain level of badness, that is, adjust the inclination angle to 0. This control method does not take advantage of the dual-axis rotating photovoltaic bracket's ability to adapt to the environment in real time, resulting in a certain waste of photovoltaic resources.

[0056] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0057] Reference Figure 1 , showing a step flow chart of an embodiment of a photovoltaic bracket wind protection control method of the present invention, the photovoltaic bracket has a first rotation step and a second rotation step, and the first rotation step is larger than the second rotation step.

[0058] The first rotation step length and the second rotation step length can be determined according to the type and performance of the photovoltaic support, and the embodiment of the present invention does not specifically limit this.

[0059] The photovoltaic support wind protection control method may specifically include the following steps:

[0060] Step 101, based on the detected first current surface wind pressure data, when determining that the photovoltaic bracket is in a windproof state, detecting second current surface wind pressure data, and controlling the photovoltaic bracket to rotate with the first rotation step and a preset initial direction;

[0061] During the operation of the photovoltaic support, the wind pressure data on its surface can be monitored in real time, that is, the first current surface wind pressure data. The first current surface wind pressure data is the surface wind pressure data detected before the photovoltaic support enters the windproof state.

[0062] When the detected first current surface wind pressure data reaches the condition for entering the windproof state, it can be determined that the photovoltaic bracket enters the windproof state.

[0063] When the photovoltaic bracket is in a windproof state, the second current surface wind pressure data of the photovoltaic bracket can be detected first. The second current surface wind pressure data is the surface wind pressure data detected after the photovoltaic bracket enters the windproof state and before it rotates. Then the photovoltaic bracket is controlled to rotate with a first rotation step and a preset initial direction. Since the photovoltaic bracket is photoelectrically converted at the maximum power generation position when it is running, the photovoltaic bracket can be controlled to start rotating at the maximum power generation position and perform wind protection.

[0064] Step 102, after the photovoltaic bracket is rotated into place, detecting third current surface wind pressure data of the photovoltaic bracket;

[0065] After the photovoltaic bracket is rotated into place, the surface wind pressure data of the photovoltaic bracket after rotation can be detected, that is, the third current surface wind pressure data. The third current surface wind pressure data is the current surface wind pressure data after the photovoltaic bracket enters the windproof state and rotates.

[0066] Step 103, determining a rotation direction according to the third current surface wind pressure data, the second current surface wind pressure data and a preset wind pressure fluctuation domain;

[0067] According to the relationship between the third current surface wind pressure data, the second current surface wind pressure data and the preset wind pressure fluctuation domain, it is determined whether the initial direction is correct, thereby determining the rotation direction.

[0068] Step 104, determining a safe position distance according to the third current surface wind pressure data, the preset wind pressure fluctuation domain and the preset wind pressure threshold;

[0069] Furthermore, the safe position distance can be determined based on the third current surface wind pressure data, the preset wind pressure fluctuation domain and the preset wind pressure threshold, and the distance between the photovoltaic bracket and the safe position when the photovoltaic bracket rotates can be judged by the safe position distance. Among them, the safe position is the position where the photovoltaic bracket can not be damaged in strong wind conditions.

[0070] Step 105: According to the safety position distance, control the photovoltaic bracket to rotate with the second rotation step or the first rotation step based on the rotation direction until the third current surface wind pressure data is less than the preset wind pressure threshold.

[0071] Based on the safe position distance, the photovoltaic bracket is controlled to rotate with the second rotation step or the first rotation step based on the rotation direction until the third current surface wind pressure data is less than the preset wind pressure threshold, that is, the photovoltaic bracket is rotated to the safe position.

[0072] The embodiment of the present invention determines that the photovoltaic bracket is in a windproof state based on the detected first current surface wind pressure data, detects the second current surface wind pressure data, and controls the photovoltaic bracket to rotate with a first rotation step and a preset initial direction; after the photovoltaic bracket is rotated to the right position, detects the third current surface wind pressure data of the photovoltaic bracket; determines the rotation direction according to the third current surface wind pressure data, the second current surface wind pressure data and the preset wind pressure fluctuation domain; determines the safe position distance according to the third current surface wind pressure data, the preset wind pressure fluctuation domain and the preset wind pressure threshold; according to the safe position distance, controls the photovoltaic bracket to rotate with the second rotation step or the first rotation step, based on the rotation direction until the third current surface wind pressure data is less than the preset wind pressure threshold. The embodiment of the present invention controls the direction angle of the photovoltaic bracket based on the detected wind pressure using the first rotation step and the second rotation step in strong wind weather, and preferentially finds a safe point near the maximum power generation position, so that the photovoltaic components are protected from damage while maintaining the power generation of the photovoltaic components as much as possible, thereby improving the power generation efficiency of the photovoltaic bracket.

[0073] Reference Figure 2 , shows a flow chart of steps of another embodiment of a photovoltaic support windproof control method of the present invention; the photovoltaic support has a first rotation step and a second rotation step, and the first rotation step is greater than the second rotation step. The first rotation step and the second rotation step can be determined according to the type and performance of the photovoltaic support, and the embodiment of the present invention does not specifically limit this.

[0074] The photovoltaic support wind protection control method may specifically include the following steps:

[0075] Step 201, determining whether the first current surface wind pressure data is less than a preset wind pressure threshold within a preset time period;

[0076] At least one sensor for detecting wind pressure can be set on the surface of the photovoltaic bracket, which can detect and obtain the first current surface wind pressure data in real time, and determine whether the first current surface wind pressure data is less than a preset wind pressure threshold within a preset time period.

[0077] When the first current surface wind pressure data within the preset time period is less than the preset wind pressure threshold, it means that even if the wind pressure is too high, it is only a transient state, not a continuous state. When the first current surface wind pressure data within the preset time period is not less than the preset wind pressure threshold, it means that even if the wind pressure is too high, it is continuous.

[0078] Among them, the preset wind pressure threshold can be set with reference to the local climate and the strength of the photovoltaic support, and the embodiment of the present invention does not make any specific limitation.

[0079] Step 202, in response to the first current surface wind pressure data being not less than a preset wind pressure threshold within a preset time period, determining that the photovoltaic bracket is in a windproof state;

[0080] When the first current surface wind pressure data within a preset time period is not less than a preset wind pressure threshold, it can be determined that the photovoltaic bracket is in a windproof state, and the photovoltaic bracket needs to be controlled to rotate to protect the photovoltaic bracket from damage.

[0081] Step 203, based on the detected first current surface wind pressure data, when determining that the photovoltaic bracket is in a windproof state, detecting second current surface wind pressure data, and controlling the photovoltaic bracket to rotate with the first rotation step and the preset initial direction;

[0082] When the photovoltaic bracket is in a windproof state, the second current surface wind pressure data can be detected first, and then the photovoltaic bracket can be controlled to rotate with a first rotation step and a preset initial direction. The preset initial direction is a preset rotation direction, which can be a clockwise direction or a counterclockwise direction, and the embodiment of the present invention does not specifically limit it.

[0083] Step 204, after the photovoltaic bracket is rotated into place, detecting third current surface wind pressure data of the photovoltaic bracket;

[0084] After the photovoltaic bracket is rotated into place, the wind pressure can be detected again by a sensor for detecting wind pressure to determine the third current surface wind pressure data of the photovoltaic bracket.

[0085] Step 205, determining a rotation direction according to the third current surface wind pressure data, the second current surface wind pressure data and a preset wind pressure fluctuation domain;

[0086] The wind pressure change is determined based on the third current surface wind pressure data and the second current surface wind pressure data, and then compared with the preset wind pressure fluctuation domain to determine the rotation direction. The preset wind pressure fluctuation domain can be determined according to the local environmental changes, and the embodiment of the present invention does not specifically limit it.

[0087] Specifically, the step of determining the rotation direction based on the third current surface wind pressure data, the first current surface wind pressure data and the preset wind pressure fluctuation domain includes: calculating the wind pressure difference between the third current surface wind pressure data and the second current surface wind pressure data; in response to the wind pressure difference being greater than a positive value of the preset wind pressure fluctuation domain, determining that the rotation direction is opposite to the preset initial direction; in response to the wind pressure difference being less than a negative value of the preset wind pressure fluctuation domain, determining that the rotation direction is the same direction as the preset initial direction.

[0088] For determining the direction of rotation, the historical direction can be determined first, and the historical direction is the direction of the last rotation. When it is the first rotation, the preset rotation direction can be the historical direction. Then the wind pressure difference between the third current surface wind pressure data and the second current surface wind pressure data is calculated, that is, the difference obtained by subtracting the first current surface wind pressure data from the third current surface wind pressure data is the wind pressure difference. The relationship between the wind pressure difference and the preset wind pressure fluctuation domain is determined to determine the specific rotation direction of the rotation.

[0089] In response to the wind pressure difference being greater than a positive value of a preset wind pressure fluctuation range, it is considered that the last rotation direction is not conducive to reducing the wind pressure, and a rotation direction different from the last rotation direction, that is, a direction opposite to the historical rotation direction, is required to quickly reach a safe position, and it can be determined that the rotation direction is opposite to the historical rotation direction;

[0090] Correspondingly, in response to the wind pressure difference being less than the negative value of the preset wind pressure fluctuation range, it is considered that the last rotation direction is conducive to reducing the wind pressure value, and it is necessary to rotate in the same direction as the last rotation direction, that is, the same direction as the historical rotation direction, in order to quickly reach a safe position. It can be determined that the rotation direction is the same as the historical rotation direction.

[0091] When the wind pressure difference is not greater than the positive value of the preset wind pressure fluctuation range and not less than the negative value of the preset wind pressure fluctuation range, it is considered that the wind pressure has not changed significantly, and it is impossible to determine whether the adjustment direction is correct. Continue to adjust the direction angle according to the step size and historical steering of the previous step.

[0092] In an optional embodiment of the present invention, the method further includes:

[0093] Step S1, in response to the wind pressure difference being greater than a positive value of a preset wind pressure fluctuation range, detecting whether the current position is a marked position;

[0094] In response to the wind pressure difference being greater than a positive value of a preset wind pressure fluctuation range, it can be detected whether the current position is a marked position. The marked position indicates that the wind pressure is near a minimum point and the wind pressure still exceeds the standard.

[0095] Step S2, when the current position is not a marked position, marking the current position;

[0096] When the current position is not a marked position, the current position is marked to form a marked position.

[0097] Step S3, when the current position is a marked position, control the photovoltaic bracket to be retracted.

[0098] When the current position is the marked position, it means that the wind pressure is near the minimum point and the wind pressure is still exceeding the standard, so the photovoltaic bracket is controlled to be retracted.

[0099] Specifically, the step of controlling the photovoltaic bracket to be folded includes: controlling the inclination angle of the photovoltaic bracket to be zero; or issuing a photovoltaic bracket retraction alarm, wherein the photovoltaic bracket retraction alarm is used to notify the user to retract the photovoltaic bracket.

[0100] When the photovoltaic bracket needs to be retracted, the inclination angle of the photovoltaic bracket can be adjusted to zero, or an alarm can be issued to notify the user to manually retract the photovoltaic bracket through the photovoltaic bracket retraction alarm.

[0101] Step 206, determining a safe position distance according to the third current surface wind pressure data, the preset wind pressure fluctuation domain and the preset wind pressure threshold;

[0102] During the determination of the rotation direction, the current surface wind pressure data and the preset wind pressure fluctuation domain may also be used to determine the fluctuation situation, and the safe position distance may be determined in combination with the preset wind pressure threshold.

[0103] Specifically, the step of determining the safe position distance based on the third current surface wind pressure data, the preset wind pressure fluctuation domain and the preset wind pressure threshold includes: calculating the absolute value of the difference between the third current surface wind pressure data and the preset wind pressure threshold; judging whether the absolute value of the difference is greater than the preset wind pressure fluctuation domain; when the absolute value of the difference is greater than the preset wind pressure fluctuation domain, determining that the safe position distance is a long distance; when the absolute value of the difference is not greater than the preset wind pressure fluctuation domain, determining that the safe position distance is a short distance, and the long distance is farther than the short distance.

[0104] In an embodiment of the present invention, the absolute value of the difference between the third current surface wind pressure data and the preset wind pressure threshold can be calculated, that is, the gap between the third current surface wind pressure data and the preset wind pressure threshold is determined. The distance from the safe position is determined based on the size relationship between the absolute value of the difference and the preset wind pressure fluctuation domain. Determine whether the absolute value of the difference is greater than the preset wind pressure fluctuation domain. When the absolute value of the difference is greater than the preset wind pressure fluctuation domain, it means that the distance between the current position and the safe position is large, and the safe position distance can be determined to be a long distance. Correspondingly, when the absolute value of the difference is not greater than the preset wind pressure fluctuation domain, it means that the distance between the current position and the safe position is small, and the safe position distance is determined to be a short distance. Among them, the long distance is far greater than the short distance. The specific value of the long distance being far greater than the short distance can be determined according to the actual situation, and the embodiment of the present invention does not make specific limitations on this.

[0105] Step 207, according to the safety position distance, controlling the photovoltaic bracket to rotate with the second rotation step length or the first rotation step length based on the rotation direction until the third current surface wind pressure data is less than the preset wind pressure threshold;

[0106] Based on different safe position distances, the photovoltaic bracket is controlled to rotate with a second rotation step or a first rotation step, based on the rotation direction until the third current surface wind pressure data is less than a preset wind pressure threshold, thereby rotating to a safe position.

[0107] Specifically, the step of controlling the photovoltaic bracket to rotate with the second rotation step or the first rotation step based on the rotation direction until the third current surface wind pressure data is less than the preset wind pressure threshold according to the safety position distance includes: in response to the safety position distance being a long distance, controlling the photovoltaic bracket to rotate with the first rotation step based on the rotation direction until the safety position distance is a short distance; in response to the safety position distance being a short distance, controlling the photovoltaic bracket to rotate with the second rotation step based on the rotation direction until the third current surface wind pressure data is less than the preset wind pressure threshold.

[0108] In practical applications, different control methods can be determined according to different safety position distances. When the safety position distance is short, it means that the current position is close to the safety position, and the second rotation step can be used to control the photovoltaic bracket to rotate based on the rotation direction, and the control ends when the third current surface wind pressure data is less than the preset wind pressure threshold.

[0109] When the distance to the safe position is a long distance, it means that the current position is far from the safe position, and the photovoltaic bracket needs to be quickly controlled to reach the vicinity of the safe position. The first step can be used to control the photovoltaic bracket to rotate based on the rotation direction, and continuously approach the safe position until the current position of the photovoltaic bracket is a short distance from the safe position. Then, when the distance to the safe position is a short distance, the second rotation step is used to control the photovoltaic bracket to rotate based on the rotation direction, and the rotation ends when the third current surface wind pressure data is less than the preset wind pressure threshold, thereby placing the photovoltaic bracket in a safe position and avoiding damage to the photovoltaic bracket.

[0110] Step 208, detecting the ambient wind speed while the photovoltaic support is in a windproof state;

[0111] A sensor for detecting wind speed may also be provided on the photovoltaic support, and the sensor is used to detect the ambient wind speed during the photovoltaic support is in the windproof state. The ambient wind speed is the wind speed of the environment in which the photovoltaic support is located.

[0112] Step 209, determining the duration of time that the ambient wind speed is less than a preset wind speed threshold;

[0113] Determine the duration of the ambient wind speed being less than the preset wind speed threshold to determine the duration of the ambient wind speed being relatively low. The preset wind speed threshold may be determined according to the photovoltaic support and the deployment environment, and the embodiment of the present invention does not specifically limit this.

[0114] Step 210, in response to the duration being greater than a preset duration threshold, controlling the photovoltaic support to exit the windproof state.

[0115] When the duration is greater than the preset duration threshold, it means that the current wind speed is relatively low and will no longer damage the photovoltaic bracket. The photovoltaic bracket can be controlled to exit the wind-proof state and the photovoltaic components can be controlled to be in the position of maximum power generation, thereby further improving the power generation efficiency of the photovoltaic bracket.

[0116] The embodiment of the present invention determines that the photovoltaic bracket is in a windproof state based on the detected first current surface wind pressure data, detects the second current surface wind pressure data, and controls the photovoltaic bracket to rotate with a first rotation step and a preset initial direction; after the photovoltaic bracket is rotated to the right position, detects the third current surface wind pressure data of the photovoltaic bracket; determines the rotation direction according to the third current surface wind pressure data, the second current surface wind pressure data and the preset wind pressure fluctuation domain; determines the safe position distance according to the third current surface wind pressure data, the preset wind pressure fluctuation domain and the preset wind pressure threshold; according to the safe position distance, controls the photovoltaic bracket to rotate with the second rotation step or the first rotation step, based on the rotation direction until the third current surface wind pressure data is less than the preset wind pressure threshold. The embodiment of the present invention controls the direction angle of the photovoltaic bracket based on the detected wind pressure using the first rotation step and the second rotation step in strong wind weather, and preferentially finds a safe point near the maximum power generation position, so that the photovoltaic components are protected from damage while maintaining the power generation of the photovoltaic components as much as possible, thereby improving the power generation efficiency of the photovoltaic bracket. In addition, during the windproof state, it is possible to monitor in real time whether the windproof state can be exited, so that the photovoltaic components can be at the maximum power generation power for a longer period of time, further improving the power generation efficiency of the photovoltaic bracket. It is also possible to determine whether it is an instantaneous strong wind by detecting the duration of wind pressure, so as to avoid the photovoltaic bracket from frequently entering the windproof state and ensure the normal operation efficiency of the photovoltaic bracket.

[0117] In order to make the implementation process of the present invention clear to those skilled in the art, an example is used as follows to illustrate:

[0118] You can refer to Figure 3 , determine whether the photovoltaic bracket enters the wind protection program, that is, enters the wind protection state.

[0119] The surface of the photovoltaic module is equipped with a sensor to detect wind pressure, and the wind pressure threshold is set to P H This value can be set according to the local climate and the strength of the photovoltaic support. When the wind pressure value P on the surface of the photovoltaic module is greater than P H When the wind pressure value is greater than P, the wind protection judgment program is started and the recorded wind pressure value is greater than P H Time T f , compared with the preset time value T0; when T fWhen <T0, the environment can be considered as transient change and the wind protection procedure will not be entered; when T f When ≥T0, the environment can be considered to be changing normally, the ambient wind speed increases, and the wind protection procedure is entered.

[0120] You can refer to Figure 4 , for the control after entering the windproof state.

[0121] The wind pressure fluctuation domain K can be set by referring to the wind pressure sensor detection resolution and the wind pressure change value generated when the photovoltaic bracket moves. Two step values ​​are set: the first rotation step ψ1 and the second rotation step ψ2, which are described by the direction angle of the photovoltaic bracket, ψ1>ψ2, where the step corresponding to ψ1 is larger, which facilitates the photovoltaic bracket to move quickly to the vicinity of the safe point closest to the maximum power generation position, and the step corresponding to ψ2 is smaller, which facilitates the photovoltaic bracket to move directly near the safe point and approach the safe point.

[0122] The photovoltaic bracket is controlled to adjust the direction angle according to the set step size and rotation direction, and the difference ΔP before and after the movement is recorded. Here, the initial step size is ψ1, and the initial rotation direction is set to clockwise.

[0123] If -K≤ΔP≤K, it is considered that the wind pressure has not changed significantly and it is impossible to determine whether the adjustment direction is correct. Continue to adjust the direction angle according to the step size and rotation direction of the previous step;

[0124] If ΔP>K, it is considered that the current rotation direction is not conducive to reducing wind pressure. It is determined whether the reset position is marked. If not, the rotation direction is adjusted to the reverse direction, the reset position is marked, and the previous step is repeated.
