Detailed Description
The invention is described in detail below with reference to specific embodiments.
As shown in fig. 1, the solar power generation apparatus 1 includes a solar power generation module 11, a voltage conversion module 12, a rectification filter module 13, a front-end feedback circuit 14, a power management system 15, a rear-end voltage stabilization feedback circuit 16, a speed regulation fan 17, and a speed regulation fan control module 18.
Sunlight irradiates on the solar power generation module 11, the solar power generation module 11 generates electric energy through a photoelectric effect, the electric energy generated by the solar power generation module 11 is input to the voltage conversion module 12, the voltage conversion module 12 converts the electric energy generated by the solar power generation module 11 into stable voltage, and the voltage conversion module 12 is a switch converter. The rectifying and filtering module 13 is connected behind the switching converter to rectify and filter the voltage waveform output by the switching converter, and the electric energy generated by the solar power generation module 11 is processed by the overvoltage conversion module 12 and the rectifying and filtering module 13 and then output to the speed regulation fan 17 and the load 2 to drive the speed regulation fan 17 and supply power to the load 2. One end of the load power supply switch module 19 is connected with the output end of the rectifying and filtering module 13, and the other end is connected with the load 2. The load power supply switch module 19 detects power that the solar power generation device can actually output to the load to control whether the solar power generation device 1 supplies power to the load 2. The front end feedback circuit 14 detects the current electric energy generated by the solar power generation module 11 and inputs the electric energy into the power management system 15, the rear end voltage stabilization feedback circuit 16 detects the voltage output by the rectification filter module 13 and inputs the voltage into the power management system 15, and the speed regulation fan control module 18 is connected to the speed regulation fan 17 to regulate and control the rotating speed of the speed regulation fan 17
When the load power supply switch module 19 detects that the power actually output to the load is < the preset threshold power:
the load power supply switch module 19 controls to cut off power supply to the load 2, and the electric energy generated by the solar power generation module 11 is processed by the overvoltage conversion module 12 and the rectification filter module 13 and then is only input to the speed regulation fan 17 to drive the speed regulation fan 17. The speed regulation fan 17 regulates and controls the rotating speed of the solar power generation module 11 according to the electric energy converted by the solar power generation module, the larger the voltage output by the rectification filter module 13 is, the faster the speed regulation fan 17 rotates, and otherwise, the slower the rotating speed of the speed regulation fan 17 is. According to the solar power generation equipment 1, unstable electric energy generated by the solar power generation equipment 1 in the unstable solar period is converted into kinetic energy of the speed regulation fan 17, the speed regulation fan 17 can adjust the rotating speed according to the input voltage, so that the solar power generation equipment 1 can still be kept in a working state under the condition that the solar energy is unstable, namely the generated power of the solar power generation equipment 1 is not enough to support the operation of the load 2, and the starting and stopping frequency of the solar power generation equipment 1 is reduced. Compared with a mode of directly using the resistor to consume unstable electric energy generated by the solar power generation equipment 1 during the solar instability, the mode of the present disclosure is safer to use, because the resistor converts the electric energy into the internal energy, and the resistor in the mode can generate heat and even burn through red, so that surrounding circuits are burnt out, and fire accidents can even be caused.
When it is detected that the electric energy actually output to the load is less than the preset threshold electric energy and | the preset threshold electric energy | - | the electric energy | generated by the solar power generation module 11 approaches to zero, the power management system 15 controls the voltage conversion module 12 to increase the voltage converted and output by the conversion module. The front-end feedback circuit 14 detects the current electric energy generated by the solar power generation module 11 and inputs the detected electric energy to the power management system 15, and when the difference between the preset threshold electric energy and the electric energy generated by the solar power generation module 11 is smaller, it indicates that the current unstable solar energy becomes stronger, and the solar power generation module 11 generates more electric energy, and needs to output more electric energy to consume the electric energy. On the other hand, since the speed-adjustable fan 17 is always consuming electric energy, when the condition that the electric energy input to the load is equal to the preset threshold electric energy is actually satisfied, the electric energy generated by the solar power generation module is the electric energy input to the load plus the electric energy consumed by the speed-adjustable fan. In cloudy weather, the power input to the load 2 from the solar power generation device 1 may reach a preset threshold power for a while and may be lower than the threshold power for a while, and thus, the power supply to the load 2 may be repeatedly turned on and off. Therefore, the method disclosed by the invention can ensure that the power supply to the load 2 is started after the solar power generation equipment 1 has certain redundancy, and the situation that the power supply to the load 2 is repeatedly started and stopped is effectively avoided by regulating and controlling the electric energy consumed by the speed regulation fan 17 through the speed regulation fan control module 18.
When the electric energy output to the load is larger than or equal to the preset threshold electric energy:
the load supply switch module 19 controls the power supply to the load 2 to be turned on,
the speed regulation fan control module 18 controls the speed regulation fan 17 to reduce the rotation speed so as to reduce the consumption of electric energy,
the power management system 15 controls the voltage conversion module 12 to maintain the voltage of the converted output by modulating the output voltage of the switching converter by the PWM signal according to the voltage detected by the back-end voltage stabilization feedback circuit 16.
In other embodiments, the speed-adjustable fan 17 is provided in plurality.
As shown in fig. 2 to 8, which are actual circuit diagrams of a solar power generation apparatus 1 according to an embodiment of the present disclosure, the voltage conversion module 12 is a switching converter in the embodiment of the present disclosure, and the power management system 15 modulates an output voltage of the switching converter by a PWM signal. The power management system 15 is an L6565D power management chip. The front-end feedback circuit 14 includes a controllable precision voltage regulator TL 431.
Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention, and not for limiting the protection scope of the present invention, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
