Description

Technical Field

[0001] This invention relates to the field of photovoltaic equipment technology, and in particular to a method for controlling the wind resistance of a photovoltaic support structure, a device for controlling the wind resistance of a photovoltaic support structure, an electronic device, and a storage medium. Background Technology

[0002] To maximize the use of sunlight for photovoltaic power generation, adjustable dual-axis rotating photovoltaic brackets are widely used in the photovoltaic power generation field. Dual-axis rotating photovoltaic brackets can adjust their tilt angle and azimuth angle in real time to keep the photovoltaic modules perpendicular to the direct direction of sunlight, so as to obtain the maximum power generation in real time.

[0003] When encountering strong winds and severe weather, the surface of photovoltaic modules is subjected to significant wind pressure. Dual-axis rotating photovoltaic supports can adjust their angle to avoid damage. Most existing control schemes simply retract the photovoltaic modules once the external weather reaches a certain level of severity, adjusting the tilt angle to 0. This control method fails to leverage the advantage of dual-axis rotating photovoltaic supports' ability to adapt to the environment in real time, resulting in a certain waste of photovoltaic resources.

[0056] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0057] Reference Figure 1 The diagram shows a flowchart of an embodiment of a photovoltaic support wind protection control method according to the present invention. The photovoltaic support has a first rotation step size and a second rotation step size, wherein the first rotation step size is greater than the second rotation step size.

[0058] The first rotation step size and the second rotation step size can be determined according to the type and performance of the photovoltaic support, etc., and the embodiments of the present invention do not specifically limit them.

[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 it is determined that the photovoltaic support is in windproof state, the second current surface wind pressure data is detected, and the photovoltaic support is controlled to rotate with the first rotation step and the preset initial direction;

[0061] During the operation of the photovoltaic support system, the wind pressure data on its surface can be monitored in real time, i.e., 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 system enters the windproof state.

[0062] When the detected first current surface wind pressure data reaches the condition for entering windproof mode, it can be determined that the photovoltaic support has entered windproof mode.

[0063] When the photovoltaic (PV) support is in windproof mode, the second current surface wind pressure data of the PV support can be detected first. This second current surface wind pressure data is the surface wind pressure data detected before the PV support rotates after entering windproof mode. Then, the PV support is controlled to rotate by a first rotation step and a preset initial direction. Since the PV support is performing photoelectric conversion at its maximum power generation position during operation, it can be controlled to begin rotating at this maximum power generation position to provide windproof protection.

[0064] Step 102: After the photovoltaic support has rotated into place, detect the third current surface wind pressure data of the photovoltaic support;

[0065] Once the photovoltaic support bracket has rotated into position, the surface wind pressure data after rotation can be measured, which is the third current surface wind pressure data. The third current surface wind pressure data represents the current surface wind pressure data after the photovoltaic support bracket enters windproof mode and undergoes rotation.

[0066] Step 103: Determine the rotation direction based on the third current surface wind pressure data, the second current surface wind pressure data, and the preset wind pressure fluctuation range;

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

[0068] Step 104: Determine the safe location distance based on the third current surface wind pressure data, the preset wind pressure fluctuation range, and the preset wind pressure threshold.

[0069] Furthermore, the safe position distance can be determined based on the current surface wind pressure data, the preset wind pressure fluctuation range, and the preset wind pressure threshold. This safe position distance is then used to determine the distance between the photovoltaic support and the safe position during rotation. The safe position is the location where the photovoltaic support will not be damaged in strong winds.

[0070] Step 105: Based on the safe position distance, control the photovoltaic bracket to rotate at 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 in the direction of rotation by the second rotation step or the first rotation step, until the current surface wind pressure data is less than the preset wind pressure threshold, which means that the photovoltaic bracket has rotated to a safe position.

[0072] This invention, in its embodiment, determines the photovoltaic (PV) support's windproof state based on detected first current surface wind pressure data. It then detects second current surface wind pressure data and controls the PV support to rotate with a first rotation step and a preset initial direction. After the PV support reaches its designated position, it detects third current surface wind pressure data. The rotation direction is determined based on the third current surface wind pressure data, the second current surface wind pressure data, and a preset wind pressure fluctuation range. A safe position distance is determined based on the third current surface wind pressure data, the preset wind pressure fluctuation range, and a preset wind pressure threshold. Based on this safe position distance, the PV support is controlled to rotate with a second or first rotation step, based on the rotation direction, until the third current surface wind pressure data is less than the preset wind pressure threshold. This invention, in strong winds, controls the azimuth angle of the PV support using the first and second rotation step steps, prioritizing finding a safe point near the location with maximum power generation. This avoids damage to the PV modules while maintaining their power generation as much as possible, thereby improving the power generation efficiency of the PV support.

[0073] Reference Figure 2 The diagram illustrates a flowchart of another embodiment of the photovoltaic support wind protection control method of the present invention; the photovoltaic support has a first rotation step size and a second rotation step size, wherein the first rotation step size is greater than the second rotation step size. The first rotation step size and the second rotation step size can be determined according to the type, performance, etc. of the photovoltaic support, and the embodiments of the present invention do not specifically limit them.

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

[0075] Step 201: Determine 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 wind pressure sensor can be installed on the surface of the photovoltaic support to detect the first current surface wind pressure data in real time and determine whether the first current surface wind pressure data is less than the preset wind pressure threshold within a preset time period.

[0077] If the first current surface wind pressure data within the preset time period is less than the preset wind pressure threshold, it indicates that even if excessive wind pressure occurs, it is only a momentary state and not a continuous state. If the first current surface wind pressure data within the preset time period is not less than the preset wind pressure threshold, it indicates that even if excessive wind pressure occurs, it is a continuous state.

[0078] The preset wind pressure threshold can be set with reference to the local climate and the strength of the photovoltaic support structure; however, this embodiment of the invention does not impose any specific limitations on it.

[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, determine that the photovoltaic support is in a windproof state;

[0080] If the first current surface wind pressure data within the preset time period is not less than the preset wind pressure threshold, it can be determined that the photovoltaic support is in a windproof state. It is necessary to control the photovoltaic support to rotate in order to protect the photovoltaic support from damage.

[0081] Step 203: Based on the detected first current surface wind pressure data, when the photovoltaic support is in windproof state, detect the second current surface wind pressure data and control the photovoltaic support to rotate with the first rotation step and the preset initial direction;

[0082] When the photovoltaic support is in windproof mode, the second current surface wind pressure data can be detected first, and then the photovoltaic support can be controlled to rotate by a first rotation step and a preset initial direction. The preset initial direction is a pre-set rotation direction, which can be clockwise or counterclockwise; this embodiment of the invention does not specify a particular direction.

[0083] Step 204: After the photovoltaic support has rotated into place, detect the third current surface wind pressure data of the photovoltaic support;

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

[0085] Step 205: Determine the rotation direction based on the third current surface wind pressure data, the second current surface wind pressure data, and the preset wind pressure fluctuation range;

[0086] The wind pressure variation is determined based on the third and second current surface wind pressure data, and then compared with a preset wind pressure fluctuation range to determine the rotation direction. The preset wind pressure fluctuation range can be determined according to local environmental changes, and this embodiment of the invention does not impose specific limitations.

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

[0088] To determine the rotation direction, we can first determine the historical rotation direction, which is the direction of the last rotation. When it's the first rotation, the preset rotation direction can be used as the historical rotation direction. Then, we calculate the wind pressure difference between the third current surface wind pressure data and the second current surface wind pressure data; that is, the wind pressure difference is the difference obtained by subtracting the first current surface wind pressure data from the third current surface wind pressure data. The specific rotation direction is then determined by judging the relationship between the wind pressure difference and the preset wind pressure fluctuation range.

[0089] If the wind pressure difference is greater than the positive value of the preset wind pressure fluctuation range, it is considered that the previous rotation direction is not conducive to reducing wind pressure. It is necessary to rotate in a different direction than the previous rotation, that is, in the opposite direction of the historical rotation, in order to quickly reach a safe position. It can be determined that the rotation direction is opposite to the historical rotation.

[0090] Correspondingly, if the wind pressure difference is less than the negative value of the preset wind pressure fluctuation range, it is considered that the previous rotation direction was conducive to reducing the wind pressure value. It is necessary to rotate in the same direction as the previous rotation, i.e. 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 of the previous step and the historical turning.

[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, detect whether the current position is a marked position;

[0094] In response to a positive value where the wind pressure difference exceeds a preset wind pressure fluctuation range, it can detect whether the current location is a marked location. A marked location indicates a point near the minimum wind pressure where the wind pressure still exceeds the limit.

[0095] Step S2: If the current position is not a marked position, mark the current position;

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

[0097] Step S3: When the current position is the marked position, control the photovoltaic bracket to retract.

[0098] When the current position is the marked position, it indicates that the wind pressure is near the minimum point and the wind pressure is still exceeding the standard, so the photovoltaic support should be retracted.

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

[0100] When it is necessary to retract the photovoltaic support, the tilt angle of the photovoltaic support can be adjusted to zero, or an alarm can be issued to notify the user to manually retract the photovoltaic support.

[0101] Step 206: Determine the safe location distance based on the third current surface wind pressure data, the preset wind pressure fluctuation range, 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 range can be used to determine the fluctuation situation, and the safe position distance can be determined in combination with the preset wind pressure threshold.

[0103] Specifically, the step of determining the safe location distance based on the third current surface wind pressure data, the preset wind pressure fluctuation range, 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; determining whether the absolute value of the difference is greater than the preset wind pressure fluctuation range; when the absolute value of the difference is greater than the preset wind pressure fluctuation range, determining the safe location distance as a long distance; when the absolute value of the difference is not greater than the preset wind pressure fluctuation range, determining the safe location distance as a short distance, wherein the long distance is greater than the short distance.

[0104] In this embodiment of the 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 can be determined. The distance to the safe position is determined based on the relationship between the absolute value of the difference and the preset wind pressure fluctuation range. It is determined whether the absolute value of the difference is greater than the preset wind pressure fluctuation range. When the absolute value of the difference is greater than the preset wind pressure fluctuation range, it indicates that the current position is far from the safe position, 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 range, it indicates that the current position is far from the safe position, and the safe position distance is determined to be a short distance. Among them, the long distance is greater than the short distance. The specific value by which the long distance is greater than the short distance can be determined according to the actual situation, and this embodiment of the invention does not make a specific limitation on this.

[0105] Step 207: Based on the safe position distance, control the photovoltaic bracket to rotate by 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.

[0106] Based on different safe position distances, the photovoltaic bracket is controlled to rotate at a second or first rotation step, and then rotates to a third safe position when the current surface wind pressure data is less than a preset wind pressure threshold.

[0107] Specifically, the step of controlling the photovoltaic bracket to rotate with the second rotation step or the first rotation step based on the safe position distance until the third current surface wind pressure data is less than the preset wind pressure threshold includes: in response to the safe position distance being a long distance, controlling the photovoltaic bracket to rotate with the first rotation step based on the rotation direction until the safe position distance is a short distance; in response to the safe 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 based on different safe position distances. When the safe position distance is short, it indicates that the current position is relatively close to the safe position. In this case, a second rotation step size can be used to control the photovoltaic support to rotate based on the rotation direction, ending when the 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 indicates that the current position is far from the safe position, and it is necessary to quickly control the photovoltaic support to move closer to the safe position. This can be achieved by first controlling the photovoltaic support to rotate based on the rotation direction, continuously approaching the safe position until the distance between the current position and the safe position is short. Then, based on the short distance to the safe position, a second rotation step is used, controlling the photovoltaic support to rotate based on the rotation direction, until a third point is reached where the current surface wind pressure data is less than the preset wind pressure threshold, thus placing the photovoltaic support in a safe position and preventing damage.

[0110] Step 208: During the windproof state of the photovoltaic support, the ambient wind speed is detected;

[0111] A wind speed sensor can also be installed on the photovoltaic (PV) mounting system. This sensor detects the ambient wind speed during the PV mounting system's windproof operation. The ambient wind speed refers to the wind speed in the environment where the PV mounting system is located.

[0112] Step 209: Determine the duration during which the ambient wind speed is less than a preset wind speed threshold;

[0113] The duration for which the ambient wind speed is lower than a preset wind speed threshold is determined, thereby defining the period of low ambient wind speed. The preset wind speed threshold can be determined based on the photovoltaic mounting system and the deployment environment; this embodiment of the invention does not impose specific limitations on it.

[0114] Step 210: In response to the duration exceeding a preset duration threshold, control the photovoltaic support to exit the windproof state.

[0115] When the duration exceeds the preset duration threshold, it indicates that the current wind speed is low and will no longer damage the photovoltaic support. The photovoltaic support can be controlled to exit the windproof state, and the photovoltaic modules can be controlled to be in the position of maximum power generation, thereby further improving the power generation efficiency of the photovoltaic support.

[0116] This invention, in its embodiment, determines the photovoltaic (PV) support's windproof state based on detected first current surface wind pressure data. It then detects second current surface wind pressure data and controls the PV support to rotate with a first rotation step and a preset initial direction. After the PV support reaches its designated position, it detects third current surface wind pressure data. The rotation direction is determined based on the third current surface wind pressure data, the second current surface wind pressure data, and a preset wind pressure fluctuation range. A safe position distance is determined based on the third current surface wind pressure data, the preset wind pressure fluctuation range, and a preset wind pressure threshold. Based on this safe position distance, the PV support is controlled to rotate with a second or first rotation step, based on the rotation direction, until the third current surface wind pressure data is less than the preset wind pressure threshold. This invention, in strong winds, controls the azimuth angle of the PV support using the first and second rotation step steps, prioritizing finding a safe point near the location with maximum power generation. This avoids damage to the PV modules while maintaining their power generation as much as possible, thereby improving the power generation efficiency of the PV support. Furthermore, during windproof mode, it can monitor in real time whether to exit windproof mode, allowing photovoltaic modules to operate at maximum power output for longer periods, further improving the power generation efficiency of the photovoltaic system. It can also determine whether a strong, momentary gust of wind is present by detecting the duration of wind pressure, preventing the photovoltaic system from frequently entering windproof mode and ensuring its normal operating efficiency.

[0117] To enable those skilled in the art to clearly understand the implementation process of the present invention, the following example is used for illustration:

[0118] You can refer to Figure 3 This determines whether the photovoltaic support system has entered the windproof procedure, i.e., entered the windproof state.

[0119] The photovoltaic module surface is equipped with sensors to detect wind pressure, and the wind pressure threshold is set to P. H This value can be set with reference to the local climate and the strength of the photovoltaic support structure. 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 prevention judgment procedure is activated. H Time T f It is compared with the preset time value T0; when T fWhen T < T0, the environment can be considered to be in transient change, and the wind protection procedure will not be initiated; when T f When the time is ≥T0, the environment can be considered to be in a state of normal change, the wind force increases, and the wind prevention procedure is initiated.

[0120] You can refer to Figure 4 This refers to the control measures implemented after entering the windproof mode.

[0121] The wind pressure fluctuation range K can be set by referring to the detection resolution of the wind pressure sensor and the wind pressure change value generated when the photovoltaic support moves. Two step sizes are set: the first rotation step size ψ1 and the second rotation step size ψ2, which are described by the direction angle of the photovoltaic support, where ψ1 > ψ2. The larger step size corresponding to ψ1 facilitates the rapid movement of the photovoltaic support to the vicinity of the safe point closest to the maximum power generation position, while the smaller step size corresponding to ψ2 facilitates the photovoltaic system to make small movements directly in the vicinity of the safe point to approach the safe point.

[0122] The photovoltaic bracket is controlled to adjust its 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 assumed 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. Determine whether the reset position has been marked. If not marked, adjust the rotation direction to the opposite direction, mark the reset position, and repeat the previous step. If the reset position has been marked, it means that the wind pressure is near the minimum point and the wind pressure is still exceeding the standard.
