Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of photovoltaic power generation monitoring, and particularly to a method, system and device for controlling the power generation of cadmium telluride power generation glass for a solar vehicle. Background Art
[0002] As an electric vehicle using photovoltaic power generation for energy storage, a solar vehicle can effectively solve the energy crisis and relieve the environmental pressure. However, the existing solar vehicles have the problem that due to the low conversion rate of the solar panels, the electric energy generated by the fixed area of the vehicle surface often cannot meet the needs of vehicle use.
[0003] To solve the above problems, cadmium telluride power generation glass can be attached to the vehicle body surface of the solar vehicle, and cadmium telluride power generation glass is deployed on each facade according to the area size, with a total of N pieces of cadmium telluride power generation glass. Finally, the power generation system charges the vehicle-mounted power battery through these power generation glasses. However, traditional high-power DCDC controllers are for large-scale photovoltaic modules on an equal plane, with high application power, high DCDC working power consumption, low conversion efficiency, and high self-cost. Therefore, if traditional centralized connection control is adopted for the vehicle-mounted cadmium telluride power generation glass, the lighting conditions of the power generation glasses on different facades vary greatly, directly reducing the photoelectric conversion rate of the cadmium telluride power generation glass.

[0053] Refer to Figures 1 to 4, in order to solve the problem that traditional high-power DCDC controllers cannot meet the power generation requirements of in-vehicle cadmium telluride power generation glass for large-scale photovoltaic modules on an equal plane, the present invention provides a power generation control method for cadmium telluride power generation glass of a solar vehicle. In this embodiment, cadmium telluride power generation glass is arranged on the vehicle to meet the power supply requirements of the solar vehicle. At the same time, according to the arrangement information of the cadmium telluride power generation glass, multiple independently controllable power generation integration units are set up to accurately control the power generation situation of each power generation integration unit, so as to ensure the stability of the cadmium telluride power generation glass during energy supply. That is, it effectively meets the photoelectric conversion energy supply requirements of the solar vehicle. It effectively solves the problem that traditional high-power DCDC controllers cannot meet the power generation requirements of in-vehicle cadmium telluride power generation glass for large-scale photovoltaic modules on an equal plane.
[0054] Specifically, in the first aspect of the present invention, a method for controlling the power generation of cadmium telluride power generation glass for a solar vehicle is provided, including: determining at least one power generation integration unit by obtaining the design information of the target vehicle and the layout information of the cadmium telluride power generation glass, so as to facilitate subsequent classification of the photoelectric conversion efficiency and integrated energy storage. Then, the real-time data information of each power generation integration unit is collected and obtained in real time, and then the real-time state of each power generation integration unit can be determined; then, according to the real-time state of each power generation integration unit and the real-time data information of each power generation integration unit, the output feedback information of each power generation integration unit is determined respectively, that is, finally, the photoelectric conversion situation and photoelectric conversion efficiency of each power generation integration unit are determined; then, according to the output feedback information of each power generation integration unit and the real-time state of each power generation integration unit, the rectification operation information of each power generation integration unit is made to ensure the stable output of each power generation integration unit. Finally, according to the rectification operation information of each power generation integration unit, the output state of each power generation integration unit can be adjusted; then, the output state of each adjusted power generation integration unit is used for energy storage output. In this embodiment, by arranging cadmium telluride power generation glass on the vehicle, the power supply demand of the solar vehicle can be met. At the same time, according to the layout information of the cadmium telluride power generation glass, multiple separately controllable power generation integration units are set to accurately control the power generation situation of each power generation integration unit, so as to ensure the stability of the cadmium telluride power generation glass during energy supply. That is, it effectively meets the photoelectric conversion energy supply demand of the solar vehicle. It effectively solves the problem that the traditional high-power DCDC controller cannot meet the power generation requirements of in-vehicle cadmium telluride power generation glass for large-scale photovoltaic modules on an equal plane. In this embodiment, it should be noted that each power generation integration unit includes: at least one cadmium telluride power generation glass in the same light intensity, that is, it can be the cadmium telluride power generation glasses adjacent to each other in the same side area of the vehicle, or a single cadmium telluride power generation glass; a control sub-unit, the control sub-unit is electrically connected to the cadmium telluride power generation glass in the same light intensity, and the control sub-unit is used to control the photoelectric conversion of the cadmium telluride power generation glass in the same light intensity. Specifically, the control sub-unit includes: a switching tube Q, a high-frequency low-resistance inductor L, a low-resistance diode D, and a high-frequency low-resistance capacitor C. The switching tube Q is connected to the output end of the current power generation integration unit. When the switching tube Q is turned on, the input voltage Vin of the current power generation integration unit supplies power to the power load through the high-frequency low-resistance inductor L, and the current linearly increases in the high-frequency low-resistance inductor L, and at the same time, electric energy is also stored in the high-frequency low-resistance inductor L; when the switching tube Q is turned off, the energy in the high-frequency low-resistance inductor L is released through the low-resistance diode D to continue to provide current for the power load, so as to realize the function of converting the input DC voltage into a lower stable output DC voltage. In addition, by controlling the duty cycle (the ratio of the conduction time to the switching period) of the switching tube, the magnitude of the output voltage can be adjusted.That is, the larger the duty cycle, the higher the output voltage, and vice versa. That is, the switch Q is connected to the output terminal in the current power generation integration unit. The switching transistor Q is used for controlling current conduction and cut-off, and can also adjust the duty cycle. The high-frequency low-resistance inductor L is electrically connected to the output terminal in the current power generation integration unit. The high-frequency low-resistance inductor L is used for filtering, energy storage and energy release. That is, during the conduction period of the switching transistor Q, the high-frequency low-resistance inductor L rectifies the input current and converts the electrical energy into magnetic energy for storage. When the switching transistor Q is cut off, the stored magnetic energy is converted back into electrical energy and released to the load through the low-resistance diode D, which plays a role in smoothing the output current and reducing the ripple of the output current. The low-resistance diode D is electrically connected to the switching transistor Q and the high-frequency low-resistance inductor L. The low-resistance diode is used for unidirectional freewheeling. That is, when the switching transistor Q is cut off, it provides a current path for the energy stored in the high-frequency low-resistance inductor L, enabling the high-frequency low-resistance inductor L to continue to release energy to the load, ensuring the continuity of the load current and avoiding the generation of excessive back electromotive force due to the sudden power-off of the inductor, thereby protecting other components in the circuit. In addition, the unidirectional conductivity of the low-resistance diode D can be utilized to ensure that the current does not flow back into the power supply when the switching transistor Q is conducting, and only allows the current to flow from the power supply to the high-frequency low-resistance inductor L and the power supply load when the high-frequency low-resistance inductor L stores energy, and the current to flow from the high-frequency low-resistance inductor L to the power supply load when releasing energy, maintaining the correct direction of the current in the circuit. The high-frequency low-resistance capacitor C is electrically connected to the low-resistance diode D and the switching transistor Q. The high-frequency low-resistance capacitor C is used for buffering and voltage stabilization. That is, the high-frequency low-resistance capacitor C is mainly used to filter out the high-frequency ripple in the output voltage Vin, making the output voltage smoother and more stable. In addition, during the transient process of the circuit, such as when the load current suddenly increases or decreases, the capacitor can temporarily provide or absorb part of the current, buffer the voltage change, and maintain the relative stability of the output voltage, ensuring the normal operation of the load device.
[0055] In this embodiment, in order to ensure the accuracy of collecting the real-time status of each power generation integration unit, the method for determining the real-time status of each power generation integration unit includes: collecting in real time the output voltage or current value of the cadmium telluride photovoltaic glass in each power generation integration unit to obtain a plurality of voltage sampling values or current sampling values; determining the sampling effective value of each power generation integration unit according to the plurality of voltage sampling values or current sampling values and in combination with the sampling period; and determining the real-time status of each power generation integration unit according to the sampling effective value of each power generation integration unit. That is, in advance, according to the sampling period of each power generation integration unit, a standard for screening valid data is formulated, and then the valid sampling values are determined according to the standard for screening valid data. For the convenience of understanding how to perform effective sampling, the following description is provided. Specifically, the method for determining the real-time status of each power generation integration unit further includes: obtaining a plurality of voltage sampling values X or a plurality of current sampling values Y; calculating the average value of the plurality of voltage sampling values X or the plurality of current sampling values Y according to the acquisition calculation period to determine the acquisition calculation average value; setting filtering and screening information according to the model specifications of the cadmium telluride photovoltaic glass in each power generation integration unit and in combination with the acquisition calculation average value; and then comparing the filtering and screening information with the voltage sampling values X or the plurality of current sampling values Y in the subsequent same sampling period to determine the sampling effective value in each power generation integration unit. That is, according to the standard for screening valid data, the output voltage or current amount that meets the energy storage is determined to ensure that the real-time status of each power generation integration unit can be detected.
[0056] For the convenience of understanding how to determine the sampling effective value of the cadmium telluride photovoltaic glass, the following example is provided. In a feasible implementation manner, voltage filtering and current filtering are respectively performed independently by their respective arrays. That is, independent filtering can be performed as follows.
[0057] Specifically, ① The voltage sampling value X or the current sampling value Y enters the nth-order array An in sequence for each calculation period, and shifts to the right from 1 to n in sequence. When running for the first time, the following filtering operation is only started after n calculation periods;
[0058] ② At each calculation period, an average value calculation is performed. The calculation formula for the average value W is as follows:
[0059]
[0060] ③ At each calculation period, the new sampling value X or Y is compared with the average value W. If it is greater than or less than m times the average value, it is regarded as a bad value and does not enter the array An, and An remains the previous value; where n and m are both natural numbers and are selected according to the debugging situation.
[0061] In this embodiment, the method for making the rectification operation information of each power generation integration unit includes: determining the output feedback information in each power generation integration unit according to the sampling effective value in each power generation integration unit; and then performing capacitance duty cycle perturbation adjustment according to the output feedback information in each power generation integration unit. That is, the output of each power generation integration unit can be adjusted by adjusting the duty cycle and PWM situation of the switching transistor Q, so as to facilitate subsequent precise control of energy storage. The output energy storage stage of each power generation integration unit can be determined respectively according to the output state of each power generation integration unit; and then integrated energy storage can be performed through the battery management board according to the output energy storage stage of each power generation integration unit.
[0062] It should be noted that since the energy storage state of each power generation integration unit can be divided into: charging state and freewheeling state.
[0063] When in the charging state, the low-resistance diode D is not conducting and is in the reverse cut-off state; the output of each power generation integration unit is respectively connected to the switching transistor Q, the high-frequency low-resistance inductor L, and the high-frequency low-resistance capacitor C to form a loop; at this time, according to the current-voltage formula of the inductor:
[0064]
[0065] At this time, integrating Equation 1 gives Equation 2:
[0066]
[0067] Then it is known that during the entire charging stage, the voltage change amount across the inductor is Equation 3:
[0068] ΔU L (+)=V in -V dc Equation 3;
[0069] Therefore, when the duration of the charging stage is Ton, then combining Equation 2 and Equation 3, the increase amount of the inductor current is Equation 4:
[0070]
[0071] When after the charging stage ends and the switching transistor Q is turned off and the whole is in the freewheeling state. At this time, the low-resistance diode D conducts normally, and the circuit forms a loop by the high-frequency low-resistance inductor L, the high-frequency low-resistance capacitor C, the voltage load resistor, and the low-resistance diode D. During the freewheeling stage, the energy of the whole circuit is provided by the high-frequency low-resistance inductor L, and the current flows out from the high-frequency low-resistance inductor L, passes through the high-frequency low-resistance capacitor C, the voltage load resistor, and finally flows into the other end of the high-frequency low-resistance inductor L through the low-resistance diode D. The voltage change amount across the high-frequency low-resistance inductor L during the entire freewheeling stage is:
[0072] ΔUL (-) = -V dc Equation 5;
[0073] When the duration of the entire freewheeling stage is Toff, according to Equation 2, the decrease in the inductor current is:
[0074]
[0075] According to the volt-second balance principle, the increase and decrease in the inductor current within one period are numerically equal, that is:
[0076] |ΔI L (+)| = |ΔI L (-)| Equation 7;
[0077] That is, according to Equations 1 to 7, and in conjunction with the real-time acquisition of the output of each power generation integration unit, the energy storage state of the corresponding power generation integration unit can be determined.

Examples of communication networks include local area networks ("LAN"), wide area networks ("WAN"), the Internet (e.g., the Internet), and end-to-end networks (e.g., ad hoc end-to-end networks), as well as any currently known or future-developed networks.
