Description

Technical Field

[0001] The present invention relates to the field of photovoltaic technology, and in particular to a heat dissipation control method, a terminal and a storage medium for electrical equipment. Background Art

[0002] The control scheme for heat dissipation devices in existing photovoltaic equipment is to start based on fixed start and stop points to dissipate heat from the photovoltaic equipment. For example, the control scheme for the heat dissipation fan in the photovoltaic equipment is to set a fixed fan start temperature. Generally speaking, the start temperature is 60°C, and the fan is controlled to start when it is greater than the start temperature and to shut down when it is less than the start temperature. However, if the same temperature point is used as a strategy for fan start and stop control in different seasons and regions, the thermal cycle amplitude will increase. For example, taking the above-mentioned starting temperature of 60°C as an example, in the winter in the north, it takes a long time from the initial startup of the photovoltaic equipment to control the heat dissipation fan to start, resulting in excessively large temperature differences between the photovoltaic equipment and its internal components throughout the day, that is, the thermal cycle amplitude is increased.

[0037] In the following description, specific details such as particular system structures and techniques are provided for purposes of illustration, not limitation, to facilitate a thorough understanding of the embodiments of the present invention. However, it will be apparent to those skilled in the art that the present invention may be practiced in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0038] The electrical equipment in the embodiments of the present invention may refer to photovoltaic equipment, such as a photovoltaic inverter. The control scheme of the present invention is primarily used to control the heat dissipation device within the photovoltaic equipment, thereby dissipating heat from the photovoltaic equipment by varying the operating state of the heat dissipation device. Exemplary heat dissipation devices include cooling fans, air conditioners, or liquid cooling modules, which dissipate heat from components within the electrical equipment when the heat dissipation device is activated. Of course, the electrical equipment may also be other devices whose operating state varies with time, weather, or climate.

[0039] Based on research, the inventors discovered that since photovoltaic equipment needs to operate in an outdoor environment and under conditions of light, and the outdoor ambient temperature and light duration will show periodic changes with changes in seasons or weather, the heat dissipation of the photovoltaic equipment will also show periodic changes during each day's operation. Specifically, in the morning, due to the temperature drop overnight and insufficient light, the heat dissipation of the photovoltaic equipment is at a low level. At noon, there is sufficient light and the outdoor ambient temperature will be higher. At this time, the heat dissipation of the photovoltaic equipment will increase, and the internal ambient temperature will also be relatively high. As time goes by, when the sun sets in the afternoon, the heat dissipation of the photovoltaic equipment gradually decreases, and the internal ambient temperature is also relatively low. The difference between the peak and valley temperature inside the equipment during the day is the thermal cycle amplitude of the photovoltaic equipment. Therefore, it is necessary to reduce the thermal cycle amplitude of the photovoltaic equipment during the day by promptly opening the heat dissipation device to dissipate heat, and promptly closing the heat dissipation device to prevent the internal ambient temperature from continuing to drop.

[0040] Furthermore, sudden weather changes, such as intermittent cloud cover, can also cause variations in the thermal cycle amplitude. In particular, intermittent cloud cover during the midday period, when sunlight is abundant, can cause a sudden drop in the load of the PV system, reducing the heat dissipation of the PV system. Once the cloud passes, the PV system restarts, causing the ambient temperature to rise again. Therefore, if the operating status of the heat dissipation device is not controlled during this period, the thermal cycle amplitude of the electrical equipment in this scenario will be large. In this case, timely adjustment of the heat dissipation device is also necessary.

[0041] In order to make the purpose, technical solutions and advantages of the present invention more clear, specific embodiments will be described below with reference to the accompanying drawings.

[0042] Figure 1 FIG. 1 is a flow chart of an implementation method of a heat dissipation control method for an electrical device according to an embodiment of the present invention. Figure 1 As shown, the heat dissipation device is used in electrical equipment. The method includes the following steps:

[0043] S101, obtaining the internal ambient temperature of the electrical device. The ambient temperature inside the electrical device can be obtained in real time.

[0044] S102: Filter the internal environment temperature. When the internal environment temperature is less than a first preset threshold, the filtering process is configured as a deep filtering process so that the rate of change of the filtered value obtained after the processing lags behind the rate of change of the internal environment temperature, thereby obtaining a lagged filtered value.

[0045] The first preset threshold should not be too large to avoid excessive thermal amplitude of the device when the temperature of the electrical equipment rises from a relatively low temperature to the first preset threshold.

[0046] S103: Determine the start and shut-off points of the heat sink based on the filtered value. When the internal ambient temperature is greater than the start point and less than the shut-off point, the heat sink is controlled to turn on and off, respectively. The shut-off point is lower than the start point, and the shut-off point is determined by the start point and a preset hysteresis value. In this embodiment, the preset hysteresis value is 10°C.

[0047] When the internal ambient temperature falls below a first preset threshold, the filtering process is configured as deep filtering. The activation point of the heat sink is determined based on the filtered value. Compared to existing fixed start-stop point control schemes, this ensures that the heat sink activates at low temperatures and activates earlier than with existing fixed start-stop point control schemes, achieving timely heat dissipation. Furthermore, the shutdown point is determined based on the activation point and a preset hysteresis value, preventing the heat sink from frequently activating and deactivating due to a continuous drop in the internal ambient temperature caused by the heat sink's operation, which would increase the number of thermal cycles.

[0048] The embodiment of the present invention performs deep filtering when the internal environment temperature is below a first preset threshold value, and changes the start and stop points accordingly based on the obtained lagged filter value, thereby ensuring that the change of the start and stop points lags behind the change of the actual internal environment temperature, so that the heat dissipation device is suitable for timely start-up at a lower temperature below the first preset threshold value, so as to dissipate heat for the electrical equipment in a timely manner, slow down the rising speed of the internal environment temperature of the electrical equipment, and reduce the peak value of the internal environment temperature, thereby reducing the thermal cycle amplitude of the electrical equipment.

[0049] In a possible implementation, step S103 determines the start point and the shut down point of the heat dissipation device according to the filtered value, including:

[0050] Get the first limit value;

[0051] When the filtered value is less than or greater than a first preset threshold, the first limit value and the filtered value are used as the starting points of the heat dissipation device respectively;

[0052] The difference between the start point and the preset return difference value is used as the shutdown point of the heat dissipation device.

[0053] In this embodiment, setting the first limit value can prevent unnecessary premature activation. In specific applications, when the internal ambient temperature of the electrical equipment is too low, activating the heat sink can affect its operating efficiency and, in severe cases, damage it. For example, if the heat sink is a fan, activating the fan when the internal ambient temperature is below 5°C may cause the fan to fail and be damaged.

[0054] In this implementation, when the filtered value is less than or greater than the first preset threshold, the first clipping value and the filtered value are used as activation points for the heat sink, respectively. This means that the first clipping value is set as the lower activation limit for the heat sink. This implementation prevents the heat sink from activating at temperatures below the first clipping value. Furthermore, at the moment the value exceeds the first preset threshold, the deep filtering process allows the heat sink to activate.

[0055] The aforementioned implementation primarily considers activating the heat sink as soon as possible in relatively low-temperature environments. In specific applications, this also involves maintaining the internal ambient temperature within a relatively high temperature range, which is greater than a first preset threshold. For example, if the outdoor ambient temperature is relatively high, or if the photovoltaic system is already operating under heavy load and high heat dissipation, the internal ambient temperature will continue to rise as the photovoltaic system operates.

[0056] In a possible implementation, the filtering process for the internal environment temperature in step S102 further includes:

[0057] When the internal environment temperature is greater than a second preset threshold, the filtering process is configured as a deep filtering process, wherein the second preset threshold is greater than the first preset threshold and the difference between the second preset threshold and the first preset threshold is less than a third preset threshold.

[0058] In this implementation, the second preset threshold is greater than the first preset threshold, which mainly takes into account how to determine the start and stop points of the heat dissipation device when the internal ambient temperature is maintained in a relatively high temperature range greater than the first preset threshold, so as to control the state of the heat dissipation device to dissipate heat for the photovoltaic device. Among them, the difference between the second preset threshold and the first preset threshold is less than the third preset threshold. The third preset threshold should not be too small to avoid the heat dissipation device from generating large energy consumption for a long time. More importantly, the third preset threshold should not be too large to control the thermal cycle amplitude of the photovoltaic device within a relatively small range. The third preset threshold is mainly determined based on the outdoor ambient temperature and the load size of the photovoltaic device to ensure that the photovoltaic device can operate normally within the temperature range corresponding to the third preset threshold when the thermal cycle amplitude is within the temperature range corresponding to the third preset threshold.

[0059] In a specific embodiment, the first preset threshold is 20° C., the second preset threshold is 50° C., and the third preset threshold is 30° C. as an example for description.

[0060] When the internal ambient temperature is greater than 50°C, the internal ambient temperature is deeply filtered, and the start point and the shutdown point are determined based on the filtered value. Similarly, based on the lagging filter value, it can be ensured that the heat dissipation device can be turned off in time after the internal ambient temperature drops from above 50°C.

[0061] In the 30° C. temperature range corresponding to the third preset threshold formed between the two sections of deep filtering, the 30° C. thermal cycle amplitude is permissible and acceptable for the normal operation of the photovoltaic device.

[0062] Based on the above introduction to the working principle of photovoltaic equipment, it can be known that the illumination time and intensity are the main factors affecting the heat dissipation of photovoltaic equipment. Since the light intensity will show a certain periodic change during the day, the heat dissipation of photovoltaic equipment will show a gradual increase from morning to noon, and a gradual decrease from noon to afternoon. Accordingly, when the heat dissipation device is working stably, the internal environment temperature will also have a corresponding rise and fall process. The above embodiments mainly involve the control process of turning on the heat dissipation device in advance, and for sudden changes in weather or the drop in internal environment temperature in the afternoon, it is also necessary to adopt corresponding control strategies to avoid excessive drop in internal environment temperature. In a possible implementation method, the start point and the shut-down point of the heat dissipation device are determined according to the filter value in step S103, and also include:

[0063] A second amplitude limit value is obtained, where the second amplitude limit value is greater than the first amplitude limit value. In this embodiment, the second amplitude limit value may be 60°C.

[0064] When the filtered value is less than the second preset threshold, the filtered value is used as the starting point of the heat dissipation device; when the filtered value is greater than the second preset threshold, the second limit value is used as the starting point of the heat dissipation device.

[0065] Specifically, when the photovoltaic equipment has been operating stably at a relatively high temperature, such as in the afternoon, if the aforementioned intermittent dark clouds appear at this time, the clouds drift and cause the light intensity to change in a short period of time. The time that the clouds block the sun is usually between a few minutes and more than ten minutes. During this period, the heat dissipation of the photovoltaic equipment decreases, and the internal environment temperature will continue to decrease. When the clouds pass, the heat dissipation of the photovoltaic equipment recovers, and the internal environment temperature will rise again. If there are a large number of clouds, multiple large-scale thermal cycles will occur repeatedly. When the filter value is greater than the second preset threshold, the second limit value is used as the starting point of the heat dissipation device, and the closing point is determined based on the starting point. It can ensure that when the internal environment temperature drops from a higher temperature to the second preset threshold, the heat dissipation device can be turned off in time, avoiding the situation where the heat dissipation device is not turned off in time, causing the internal environment temperature to continue to drop to a lower temperature and then recover, resulting in multiple and large-scale thermal cycles, such as Figure 2 shown.

[0066] In a possible implementation, filtering the internal environment temperature further includes:

[0067] When the internal environment temperature is greater than the first preset threshold and less than the second preset threshold, the filtering process is configured as a shallow filtering process so that the change rate of the filtered value obtained after processing follows the change rate of the internal environment temperature.

[0068] This implementation method takes into account that the thermal cycle amplitude is large within a day, and the obtained internal environment temperature may fall within a temperature range lower than a first preset threshold and greater than a second preset threshold.

[0069] The filtering processing of the internal environment temperature specifically includes: when the internal environment temperature is less than a first preset threshold, the filtering processing is configured as deep filtering processing; when the internal environment temperature is greater than the first preset threshold and less than a second preset threshold, the filtering processing is configured as shallow filtering processing; when the internal environment temperature is greater than the second preset threshold, the filtering processing is configured as deep filtering processing.

[0070] The use of shallow filtering during the internal ambient temperature range from the first preset threshold to the second preset threshold ensures that the rate of change of the filtered value follows the rate of change of the internal ambient temperature, thus preventing frequent starts and stops of the heat sink. For example, since the difference between the first and second preset thresholds (the third preset threshold) is 30°C, which is an allowable and acceptable thermal cycling range, maintaining the current state of the heat sink within this temperature range can prevent frequent starts and stops of the heat sink, which could lead to unstable internal ambient temperature, thereby facilitating heat dissipation control. Furthermore, this processing also helps improve the smoothness and stability of heat dissipation control.

[0071] Furthermore, in a possible implementation, filtering the internal environment temperature further includes:

[0072] Obtain the changing trend of internal environment temperature;

[0073] When the internal ambient temperature is greater than the first preset threshold and less than the second preset threshold and the change trend of the internal ambient temperature is a downward trend, the filtering process is configured as a deep filtering process to ensure that the heat dissipation device can be turned off in time when the temperature drops, so that the electrical equipment can be naturally cooled and the thermal cycle amplitude is reduced.

[0074] In a possible implementation, filtering the internal environment temperature further includes:

[0075] When the internal environment temperature is greater than the first preset threshold and less than the second preset threshold, and the change trend of the internal environment temperature is an upward trend, the filtering process is configured as a shallow filtering process, so that the change rate of the filtered value obtained after processing follows the change rate of the internal environment temperature, ensuring that the heat dissipation device remains turned on when the temperature rises, and ensuring that the electrical equipment is reliably cooled by the heat dissipation device.

[0076] In a possible implementation, the method further includes: determining a second amplitude limit value and a second preset threshold value according to the outdoor ambient temperature and / or the load average value.

[0077] Among them, when the load of the photovoltaic equipment is constant, the higher the outdoor ambient temperature, the lower the heat exchange rate between the internal environment and the outdoor environment, and the higher the internal ambient temperature, the higher the corresponding second limit value and the second preset threshold.

[0078] Different regions, or even different seasons within the same region, experience varying light intensities, resulting in corresponding load values. Furthermore, since light intensity fluctuates periodically throughout the day, determining the second limiter and second preset threshold based on the average load value can improve the accuracy of heat dissipation control. Under the same outdoor ambient temperature conditions, with the heat exchange rate between the indoor and outdoor environments remaining the same, a higher average load value corresponds to a higher second limiter and second preset threshold.

[0079] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0080] The following are device embodiments of the present invention. For details not fully described therein, reference may be made to the corresponding method embodiments described above.

[0081] Figure 3 A schematic diagram of the structure of a heat dissipation control device for electrical equipment provided by an embodiment of the present invention is shown. For ease of explanation, only the parts related to the embodiment of the present invention are shown, which are described in detail as follows:

[0082] like Figure 3 As shown, the heat dissipation control device for electrical equipment includes: an acquisition module 301 , a filtering module 302 and a control module 303 .

[0083] The acquisition module 301 is used to acquire the internal ambient temperature of the electrical device, wherein the ambient temperature inside the electrical device can be acquired in real time.

[0084] The filtering module 302 is configured to filter the internal environment temperature. When the internal environment temperature is less than a first preset threshold, the filtering process is configured as a deep filtering process, so that the rate of change of the filtered value obtained after the processing lags behind the rate of change of the internal environment temperature, thereby obtaining a lagged filtered value.

[0085] Control module 303 is configured to determine the start and shut-off points of the heat sink based on the filtered value, and to control the heat sink to turn on and off when the internal ambient temperature is greater than the start point and less than the shut-off point, respectively. The shut-off point is lower than the start point and is determined by the start point and a preset differential value. In this embodiment, the preset differential value is 10°C.

[0086] When the internal ambient temperature falls below a first preset threshold, the filtering process is configured as deep filtering. The activation point of the heat sink is determined based on the filtered value. Compared to existing fixed start-stop point control schemes, this ensures that the heat sink activates at low temperatures and activates earlier than with existing fixed start-stop point control schemes, achieving timely heat dissipation. Furthermore, the shutdown point is determined based on the activation point and a preset hysteresis value, preventing the heat sink from frequently activating and deactivating due to a continuous drop in the internal ambient temperature caused by the heat sink's operation, which would increase the number of thermal cycles.

[0087] The embodiment of the present invention performs deep filtering when the internal environment temperature is below a first preset threshold value, and changes the start and stop points accordingly based on the obtained lagged filter value, thereby ensuring that the change of the start and stop points lags behind the change of the actual internal environment temperature, so that the heat dissipation device is suitable for timely start-up at a lower temperature below the first preset threshold value, so as to dissipate heat for the electrical equipment in a timely manner, slow down the rising speed of the internal environment temperature of the electrical equipment, and reduce the peak value of the internal environment temperature, thereby reducing the thermal cycle amplitude of the electrical equipment.
