Technical Field

[0002] Photovoltaic power generation is a technology that directly converts light energy into electrical energy by using the photovoltaic effect at the semiconductor interface. It mainly consists of three major parts: solar panels (modules), controllers, and inverters, and the main components are composed of electronic components. Solar cells can be encapsulated and protected after being connected in series to form large-area solar cell modules, and then combined with components such as power controllers to form a photovoltaic power generation device. However, during the operation of a photovoltaic power generation system, due to the instability and intermittency of photovoltaic power generation, it may cause reactive power imbalance in the power grid. Reactive power imbalance has a negative impact on the stability and power quality of the power grid, and reactive power compensation is usually used to solve this problem.

Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0069] Figure 1 is a schematic structural diagram of a reactive power compensation device for a photovoltaic power station according to an embodiment of the present invention, as Figure 1 shown, and with reference to Figures 2 to 4 , an embodiment of the present invention provides a reactive power compensation device for a photovoltaic power station. The reactive power compensation device for a photovoltaic power station includes a frame 10, a reactive power compensation device 20, a top cover assembly 40, a plurality of baffles 50, a plurality of air cleaning devices 30, and an environment detection device.

[0070] The frame 10 includes a plurality of connecting rods. The frame 10 is used for supporting, and the structure of the frame 10 is conducive to heat dissipation. The reactive power compensation device 20 is installed on the frame 10. The top cover assembly 40 is arranged at the upper end of the frame 10. The top cover assembly 40 is used to close the upper end of the frame 10, can block rain, and is used to protect the devices inside the frame 10. A plurality of baffles 50 are sequentially installed on the frame 10 along the circumferential direction of the frame 10 through an installation structure. The installation structure is configured such that the corresponding baffle 50 is rotatably arranged around its two vertical edges on both sides. The plurality of baffles 50 are used to close the four sides of the frame 10. The baffle 50 can be opened and closed. When opened, it can be used for heat dissipation of the reactive power compensation device 20 on the frame 10. When the baffle 50 is closed, it protects the devices inside the frame 10. Each air cleaning device 30 is arranged between a baffle 50 and the frame 10 and is configured to clean the air flowing through it. Each air cleaning device 30 has a plurality of different cleaning gears. By setting the air cleaning device 30, when the baffle 50 is opened, it can prevent foreign matters such as dust from entering the frame 10. Different cleaning gears can be selected according to the different impurities in the external air to maximize heat dissipation. The environment detection device is configured to detect at least the temperature, air cleanliness, humidity, wind force and wind direction of the environment where the photovoltaic power station reactive power compensation equipment is located, so as to control the rotation of the baffle 50 around the corresponding vertical edge of the baffle and the air cleaning device 30 according to the temperature, air cleanliness, humidity, wind force and wind direction.

[0071] For the photovoltaic power station reactive power compensation equipment according to the embodiment of the present invention, due to the provision of the openable and closable baffle 50, the frame 10 and the internal reactive power compensation device 20 can be exposed, and the heat dissipation effect of the reactive power compensation device 20 can be significantly improved. Moreover, the setting of the air cleaning device 30 can optimize the unity of heat dissipation and dust prevention. Through the environment detection device, the environment can be detected, the baffle 50 and the air cleaning device 30 can be controlled, the heat dissipation and dust prevention of the photovoltaic power station reactive power compensation equipment can be automatically realized, automatic heat dissipation can be achieved, and the external environment can be reasonably utilized to save energy as much as possible during heat dissipation.

[0072] In some embodiments of the present invention, such as Figure 8As shown, the reactive power compensation device of the photovoltaic power station further includes a fan 60. The top cover assembly 40 is arranged at the upper end of the frame 10. An air outlet 43 and a fan installation cavity 41 are defined in the top cover assembly 40. The air outlet 43 communicates with the fan installation cavity 41. The inlet of the fan installation cavity 41 faces downward. The fan 60 is installed in the fan installation cavity 41 and is configured to urge air flow to flow from the frame 10 below it to the air outlet 43. An air inlet 51 is provided at the lower end of each baffle 50. By providing the fan 60, when natural heat dissipation cannot meet the heat dissipation requirements, the heat dissipation effect of the reactive power compensation device of the photovoltaic power station is ensured, and the normal operation of the reactive power compensation device of the photovoltaic power station is ensured. Due to the presence of the baffle 50, external natural wind can be used for heat dissipation. Combining with the fan 60, the fan 60 does not need to work at full power, and the energy-saving effect is obvious.

[0073] In some embodiments of the present invention, as Figures 4 to 7 shown, the installation structure is configured such that the corresponding baffle 50 is rotatably arranged around its two vertical edges on both sides, and when the corresponding baffle 50 rotates around one of its vertical edges, the other vertical edge of the corresponding baffle 50 is allowed to disengage from the installation structure. By providing the installation structure, the baffle can be selected to open around one side or the other according to requirements, which is beneficial for guiding air or blocking wind, enabling external air flow to enter the frame 10 and improving the utilization rate of natural wind.

[0074] In some embodiments of the present invention, as Figures 4 to 7 shown, each installation structure is a baffle frame 52. The baffle 50 is installed in the baffle frame 52. The baffle frame 52 is rotatably installed on the frame 10 around one of its edges, and the baffle is rotatably installed on the baffle frame 52 around the other edge of the baffle frame 52. When the baffle rotates around one side of it, the baffle frame 52 and the baffle 50 are driven by a motor to rotate synchronously to realize the opening and closing of the baffle 50. When the baffle 50 rotates around the other side of it, the baffle 50 is driven by a motor to rotate relative to the baffle frame 52, and the baffle frame 52 remains stationary relative to the frame 10 to realize the opening and closing of the baffle 50.

[0075] In some embodiments of the present invention, as Figure 10 shown, the two vertical edges on both sides of each baffle 50 are respectively a first vertical edge and a second vertical edge. A first rotating shaft 12 is installed at the first vertical edge, and a second rotating shaft 13 is installed at the second vertical edge. Corresponding first half grooves 11 and second half grooves are provided at corresponding positions on the frame 10. The first rotating shaft 12 is located in the first half groove 11, and the second rotating shaft 13 is located in the second half groove.

[0076] The installation structure includes a first arc-shaped plate 14, a second arc-shaped plate 15, a first motor, and a second motor. The first arc-shaped plate 14 is rotatably installed on the frame 10 and is located within the first half-slot 11. Driven by the first motor, the first arc-shaped plate 14 can rotate to the outside of the first rotating shaft 12, forming a rotating shaft hole with the first half-slot 11 to prevent the first rotating shaft 12 from disengaging from the first half-slot 11, enabling the baffle 50 to rotate around the first rotating shaft 12. Also driven by the first motor, the first arc-shaped plate 14 can rotate to the inside of the first rotating shaft 12 and be located within the first half-slot 11, allowing the first rotating shaft 12 to disengage from the first half-slot 11. The second arc-shaped plate 15 is rotatably installed on the frame 10 and is located within the second half-slot. Driven by the second motor, the second arc-shaped plate 15 can rotate to the outside of the second rotating shaft 13, forming a rotating shaft hole with the second half-slot to prevent the second rotating shaft 13 from disengaging from the second half-slot, enabling the baffle to rotate around the second rotating shaft 13. Also driven by the second motor, the second arc-shaped plate 15 can rotate to the inside of the second rotating shaft 13 and be located within the second half-slot, allowing the second rotating shaft 13 to disengage from the second half-slot. This arrangement enables the baffle to rotate around the first rotating shaft 12 or the second rotating shaft 13 to open as required. Further, the first rotating shaft 12 is connected to a third motor through a gear transmission device 16. When the first rotating shaft 12 is within the rotating shaft hole formed by the first arc-shaped plate 14 and the first half-slot 11, the third motor drives the first rotating shaft 12 to rotate through the gear transmission device 16 to open the baffle 50. The second rotating shaft 13 is connected to a fourth motor through the gear transmission device 16. When the second rotating shaft 13 is within the rotating hole formed by the second arc-shaped plate 15 and the second half-slot, the fourth motor drives the second rotating shaft 13 to rotate through the gear transmission device to open the baffle 50.

[0077] In some alternative embodiments of the present invention, a single motor can be employed to simultaneously drive the first arc-shaped plate 14 and the second arc-shaped plate 15 to rotate synchronously through a transmission structure, and both the first arc-shaped plate 14 and the second arc-shaped plate 15 have three positions, namely a first position for forming a rotating shaft hole, a second position for allowing the first rotating shaft 12 / second rotating shaft 13 to disengage, and a third position for incompletely blocking the first rotating shaft 12 / second rotating shaft 13 to prevent the first rotating shaft 12 / second rotating shaft 13 from disengaging. For example, a sprocket is provided on the output shaft of the first motor, and the first arc-shaped plate 14 and the second arc-shaped plate 15 are also each connected to a sprocket, with a single chain wound around the three sprockets. The sprocket on the output shaft of the first motor can be on the inner or outer side of the chain.

[0078] In some embodiments of the present invention, such as Figure 11As shown, the first motor is also used to drive the baffle 50 to rotate around the first rotating shaft 12. Specifically, a first gear 71 is provided on the output shaft of the first motor. The upper end of the first rotating shaft 12 has a polygonal structure. An electromagnet 72 and a rotatable and vertically movable gear shaft 73 are provided on the frame 10. A polygonal drive hole is provided at the lower end of the gear shaft 73, and the upper end of the first rotating shaft 12 is inserted into the drive hole. The gear shaft 73 is made of a magnetic material. A second gear 74 is rotatably provided on the gear shaft 73 and a third gear 75 is fixedly provided. The electromagnet 72 is used to drive the gear shaft 73 to move upward, so that the gear shaft 73 is disengaged from the first rotating shaft 12, and the first gear 71 is engaged with the second gear 74. The first arc-shaped plate 14 is vertically movably mounted on the second gear 74 and rotates under the drive of the second gear 74. When the first rotating shaft 12 is inserted into the drive hole, the third gear 75 is engaged with the first gear 71.

[0079] The second motor is also used to drive the baffle to rotate around the second rotating shaft 13. The second motor and the second rotating shaft 13 can adopt the same structure as above.

[0080] In the initial position, the first rotating shaft 12 is inserted into the drive hole, and the third gear 75 is engaged with the first gear 71. In order to make the baffle rotate around the second rotating shaft 13: first, the electromagnet 72 drives the corresponding gear shaft 73 to move upward, so that the second gear 74 is engaged with the first gear 71, and the first motor drives the first arc-shaped plate 14 to rotate, allowing the first rotating shaft 12 to disengage. Then, the second motor drives the corresponding first gear 71 to drive the third gear 75 to rotate. When closing the baffle 50, the second motor drives the corresponding first gear 71 to drive the third gear 75 to rotate to close the baffle, and the first motor drives the first arc-shaped plate 14 to rotate in the reverse direction. After reaching the stop position, the electromagnet 72 is released, and the gear shaft 73 descends to complete the stop. At this time, the first gear 71 and the third gear 75 are engaged and can be locked.

[0081] In some embodiments of the present invention, an installation hole for the second gear 74 is provided on the frame 10, and the second gear 74 is arranged in the installation hole. An annular rotating groove 78 is provided on the hole wall of the installation hole, and a plurality of notch grooves 79 communicating with the annular brick groove and penetrating upward through the frame are provided. A plurality of rotating blocks 77 are provided on the outer wall of the second gear 74, and the rotating blocks 77 rotate in the annular rotating groove 78. The second gear 74 is located below the third gear 75. First, the electromagnet 72 drives the corresponding gear shaft 73 to move upward. At this time, the rotating block 77 moves upward from the annular rotating groove 78 through the notch groove 79, so that the second gear 74 is engaged with the first gear 71. Then, driving the first arc-shaped plate 14 to rotate, the rotating block 77 rotates synchronously, that is, the rotating block 77 is used to rotate on the upper end surface of the frame and leave the position of the notch groove 79, and the gear shaft 73 will not move downward. At this time, the electromagnet can be powered off, so that the electromagnet 72 will not be in the working state all the time.

[0082] In some embodiments of the present invention, the first rotating shaft 12 and the second rotating shaft 13 are both fixedly arranged on the frame 10. On the frame 10, a first stop block and a second stop block are sequentially arranged along the width direction of the baffle (for example, the left-right direction). First stop block limit grooves, second stop block limit grooves, first rotating shaft chutes and second rotating shaft chutes are arranged on both the upper end surface and the lower end surface of the baffle. The openings of the first stop block limit grooves, the second stop block limit grooves, the first rotating shaft chutes and the second rotating shaft chutes all face the frame 10.

A first gear is arranged at a position on the baffle close to the first rotating shaft, and a second gear is arranged at a position close to the second rotating shaft. A first motor and a second motor are arranged on the frame 10. A third gear is arranged on the output shaft of the first motor, and a fourth gear is arranged on the output shaft of the second motor.

[0083] As shown in the figure, in the initial state, the first stop block is in the first stop block limit groove and is on the front side of the third stop block, and the second stop block is in the second stop block limit groove and is on the front side of the fourth stop block, preventing the baffle from detaching from the frame 10. The first gear and the third gear are spaced apart, and the second gear and the fourth gear are spaced apart. The first rotating shaft is in the first rotating shaft chute, and the second rotating shaft is in the second rotating shaft chute.

[0084] After the baffle slides to the right, the first rotating shaft on the left side enters the first rotating shaft hole, the first gear and the third gear are engaged, the first stop block moves to the left side of the third stop block, and the second stop block moves to the left side of the fourth stop block. At this time, the first motor rotates, driving the third gear 75 and the first gear 71 to rotate, for opening and closing the baffle. After the baffle is closed, the baffle slides to the left to reset. Similarly, after the baffle slides to the left, the second rotating shaft on the right side enters the second rotating shaft hole, the second gear and the fourth gear are engaged, the first stop block moves to the right side of the third stop block, and the second stop block moves to the right side of the fourth stop block. At this time, the second motor rotates, driving the fourth gear and the second gear to rotate, for opening and closing the baffle. After the baffle is closed, the baffle slides to the right to reset.

[0085] Further, in order to facilitate the left and right movement of the baffle, a chute is arranged inside the baffle, and a swing motor is arranged on the frame 10. The swing shaft of the swing motor is inserted into the chute, which can drive the left and right sliding of the baffle, but does not affect the detachment between the baffle and the swing shaft, allowing the baffle to be opened and closed.

[0086] In some embodiments of the present invention, all the motors are self-locking motors, that is, the first motor and the second motor are both locking motors. When the baffle is in the closed state, if there is no power, the baffle cannot be opened.

A valve can be provided at the water inlet to control the on-off of the water channel.

[0088] In some embodiments of the present invention, the reactive power compensation device of the photovoltaic power station further includes a lower water storage cavity, a circulating water pump, and a waste water outlet pipe. The water outlet is communicated with the lower water storage cavity, and the lower water storage cavity can be arranged underground for heat dissipation and cooling water. The circulating water pump has two outlets. The inlet of the circulating water pump is communicated with the lower water storage cavity. One outlet of the circulating water pump is communicated with the water storage cavity 44 via a pipeline, and the other outlet is communicated with the inlet of the waste water outlet pipe. Such a setting can achieve circulating water cooling. When it rains, waste water can be discharged for water replacement.

[0089] In some embodiments of the present invention, as Figure 8 shown, the top cover assembly 40 includes two inclined plates 45 and two vertical plates 46. The upper ends of the two inclined plates 45 are connected, and the two vertical plates 46 are arranged at both ends of the two inclined plates 45. An air outlet 43 is provided on each inclined plate 45, and a water baffle 47 is arranged at the lower edge of the air outlet 43 to promote rainwater to enter the air outlet 43. There are two water storage cavities 44, and the fan 60 installation cavity is between the two water storage cavities 44. A wind channel 48 is provided on the upper side of the water storage cavity 44 to connect the fan installation cavity 41 and the air outlet 43. Drainage holes 49 are also provided on the two inclined plates 45. The drainage holes 49 are located below the water baffle 47 to prevent the water in the water storage cavity 44 from overflowing into the frame 10. Further, a shielding block is arranged below the water baffle 47 to shield the drainage holes 49 so that the openings of the drainage holes face downward to prevent dust and other impurities from entering the drainage holes 49.

[0090] Further, as Figure 8As shown in the figure, the upper wall of the air duct 48 includes a vertical section 481, a first inclined section 482, a second inclined section 483, and a first air guiding section 484. The upper end of the vertical section 481 is connected to the upper edge of the air outlet 43. The lower end of the first inclined section 482 is connected to the lower end of the vertical section 481 and is located inside the vertical section 481. The upper end of the second inclined section 483 is connected to the upper end of the first inclined section 482, and the lower end of the second inclined section 483 is connected to the first air guiding section 484.

[0091] In some embodiments of the present invention, the air outlet 43 is also used for water inlet. When the fan is operating, impurities discharged from the air outlet 43 can be blown away, preventing the impurities from entering the water storage cavity 44 along with rainwater. Further, a filter screen 42 is also provided at the air outlet 43.

[0092] In some embodiments of the present invention, the reactive power compensation device of the photovoltaic power station further includes a control input and display device 70, which is provided on the side wall of the top cover assembly 40. The control input and display device 70 can be a touch screen. It is provided on the side wall of the top cover assembly 40, especially on two vertical plates 46.

[0095] The reactive power compensation device of the photovoltaic power station in the embodiment of the present invention has a good heat dissipation effect, which is beneficial to improving the efficiency of converting green energy solar energy into electric energy, improving the utilization rate of solar energy, that is, improving the utilization rate of green environmental protection energy; and reducing its own power consumption, without causing energy waste, that is, being able to achieve remarkable energy conservation and emission reduction effects. That is to say, the reactive power compensation device of the photovoltaic power station of the present invention has small self-consumption, and makes the photovoltaic network, solar energy network, and power grid where the reactive power compensation device of the photovoltaic power station is located generate more electricity, and can make more use of green energy under the condition of energy conservation and emission reduction, with remarkable effects.

[0096] As Figure 12 shown, the embodiment of the present invention also provides a compensation method for the reactive power compensation device of the photovoltaic power station in any of the above embodiments, which includes:

[0097] Step S100, detecting the temperature, air cleanliness, humidity, wind force, and wind direction of the environment where the reactive power compensation device of the photovoltaic power station is located.

[0098] Step S200, controlling the baffle and the air cleaning device 30 according to the temperature, air cleanliness, humidity, wind force, and wind direction.

[0099] Specifically, controlling the baffle and the air cleaning device 30 according to the temperature, air cleanliness, humidity, wind force, and wind direction specifically includes:

[0100] Judging whether the temperature is higher than the temperature preset value, and judging whether the humidity is less than the humidity preset value.

[0101] When the temperature is higher than the temperature preset value and the humidity is less than the humidity preset value, control the opening angle and opening direction of each baffle according to the wind force, and control the air cleaning device 30 according to the air cleanliness. Otherwise, obtain the temperature inside the frame 10 and control the fan according to the temperature inside the frame 10.

[0102] For example, in winter, when the temperature is relatively low, it is not necessary to open each baffle. In summer, when the temperature is relatively high, it is best to open each baffle, which can significantly improve the heat dissipation capacity of the reactive power compensation device of the photovoltaic power station and make the reactive power compensation device 20 work efficiently.

[0103] In some embodiments of the present invention, as Figures 13 to 17As shown, there are four baffles 50 and four air cleaning devices 30. According to the wind force, the opening angles and opening directions of each baffle 50 are controlled, specifically including:

[0104] Judge whether the wind force is less than the first wind force preset value.

[0105] If the wind force is less than the first wind force preset value, multiple baffles 50 are opened synchronously by a preset angle, as Figure 13 shown.

[0106] If the wind force is greater than the first wind force preset value, determine the included angle between each baffle and the horizontal component of the wind direction according to the wind direction. The arrow in the figure can represent the horizontal component of the wind direction.

[0107] Judge whether there is a baffle with an included angle greater than 85°. If so, determine the baffle with an included angle greater than 85° and facing the wind as the first baffle 81, the baffle opposite to the first baffle 81 as the third baffle 83, and the remaining two baffles as the second baffle 82 and the fourth baffle 84 respectively. The first baffle 81, the second baffle 82, the third baffle 83, and the fourth baffle 84 are arranged in a clockwise direction in sequence. Otherwise, determine that the two baffles facing the wind are respectively the fifth baffle 85 and the sixth baffle 86, and the remaining two baffles are the seventh baffle 87 and the eighth baffle 88 respectively. The fifth baffle 85, the sixth baffle 86, the seventh baffle 87, and the eighth baffle 88 are arranged in a clockwise direction in sequence.

[0108] Judge whether the wind force is less than the second wind force preset value. The first wind force preset value is less than the second wind force preset value.

[0109] If so, open the second baffle 82 with the windward side edge of the second baffle 82 as the axis. The opening angle of the second baffle 82 is greater than 90° and less than 180°. Open the first baffle 81 with the vertical edge on the side away from the second baffle 82 of the first baffle 81 as the axis. The opening angle of the first baffle 81 is greater than 90° and less than 180°. Open the fourth baffle 84 with the leeward side edge of the fourth baffle 84 as the axis. The opening angle of the fourth baffle 84 is less than 90°. Open the third baffle 83 with the vertical edge on the side away from the fourth baffle 84 of the third baffle 83 as the axis. The opening angle of the third baffle 83 is greater than 180°. Or, open the fifth baffle 85 with the leeward side edge of the fifth baffle 85 as the axis. The opening angle of the fifth baffle 85 is less than 90°. Open the sixth baffle 86 with the leeward side edge of the sixth baffle 86 as the axis. The opening angle of the sixth baffle 86 is less than 90°. Open the seventh baffle 87 with the vertical edge on the side away from the sixth baffle 86 of the seventh baffle 87 as the axis. The opening angle of the seventh baffle 87 is greater than 90° and less than 180°. Open the eighth baffle 88 with the vertical edge on the side away from the fifth baffle 85 of the eighth baffle 88 as the axis. The opening angle of the eighth baffle 88 is greater than 90° and less than 180°, and the eighth baffle 88 is parallel to the seventh baffle 87.

[0110] If not, open the second baffle 82 with the windward side edge of the second baffle 82 as the axis, and the opening angle of the second baffle 82 is less than 45°. Open the fourth baffle 84 with the windward side edge of the fourth baffle 84 as the axis, and the opening angle of the fourth baffle 84 is less than 45°. Open the third baffle 83 with the vertical edge on the side of the third baffle 83 away from the fourth baffle 84 as the axis, and the opening angle of the third baffle 83 is less than or equal to 90°. Alternatively, open the seventh baffle 87 with the vertical edge on the side of the seventh baffle 87 close to the sixth baffle 86 as the axis, and the opening angle of the seventh baffle 87 is less than 90°. Open the eighth baffle 88 with the vertical edge on the side of the eighth baffle 88 close to the fifth baffle 85 as the axis, and the opening angle of the eighth baffle 88 is less than 90°.

[0111] With this setting, it is possible to reasonably adjust according to the wind direction, make full use of natural wind for cooling as much as possible, and minimize the opening of the fans. Especially for the extremely strong wind state, it is not suitable to open the baffles for air intake at this time. The windward baffles can be kept closed, and the reactive power compensation device 20 can be cooled by the negative pressure drainage of the large air volume.

[0112] In some embodiments of the present invention, controlling the air cleaning device 30 according to the air cleanliness includes:

[0113] Judging whether the baffle corresponding to the air cleaning device 30 is open.

[0114] When the baffle corresponding to the air cleaning device 30 is open, judge whether the air cleaning device 30 is used for air intake.

[0115] If so, determine the cleaning gear according to the relationship table between the air cleanliness and the air cleaning device 30 for air intake.

[0116] If not, determine the cleaning gear according to the relationship table between the air cleanliness and the air cleaning device 30 for air outlet. When the air cleanliness is the same, the cleaning ability of the cleaning gear of the air cleaning device 30 for air intake is higher than that of the cleaning gear of the air cleaning device 30 for air outlet. When the wind force is less than the first wind force preset value, the air cleaning device 30 corresponding to each baffle is the air cleaning device 30 for air intake. When the baffle is closed, the air cleaning device 30 corresponding to the baffle is the air cleaning device 30 for air intake.

[0117] By adjusting according to the air cleanliness, while ensuring the air cleanliness, the heat dissipation area can be expanded as much as possible, and the heat dissipation efficiency can be improved. The air cleanliness is usually expressed by the dust content. That is, the air cleanliness is determined according to the detected dust content in the air.

[0118] In some embodiments of the present invention, when the temperature is higher than the preset temperature value and the humidity is lower than the preset humidity value, the compensation method further includes: obtaining the temperature inside the frame 10 and controlling the fan according to the temperature inside the frame 10. To ensure the operation of the reactive power compensation device 20, the fan is appropriately turned on according to the requirements when the baffle is opened.

[0119] In some embodiments of the present invention, the compensation method further includes: when the reactive power compensation device 20 is operating, the circulating water pump is always in an operating state. It is detected whether it is raining through the environmental detection device. When it is raining, the waste water outlet pipe is connected to the circulating water pump, and the rising speed of the water level in the water storage chamber 44 is detected. The rotation speed of the circulating water pump is controlled according to the rising speed of the water level, so that after the water level in the water storage chamber 44 reaches the preset height, the rising speed of the water level becomes zero. This prevents rainwater exceeding the water volume in the water storage chamber 44 from entering the frame 10 through the air duct 48.

[0120] The compensation method of the photovoltaic power station reactive power compensation device according to the embodiments of the present invention can enable the photovoltaic power station reactive power compensation device to dissipate heat with as little electrical energy as possible, make full use of various natural conditions that can dissipate heat for heat dissipation, and has obvious energy-saving and emission-reduction effects. At the same time, it can enable the photovoltaic power station reactive power compensation device to operate stably with high efficiency under different conditions. This is beneficial to improving the efficiency of converting green energy solar energy into electrical energy, improving the utilization rate of solar energy, that is, improving the utilization rate of green environmental protection energy, that is, being able to make more use of green energy under the condition of energy conservation and emission reduction, with remarkable effects.
