Brief Description of the Drawings
[0036] Figure 1 It is a block diagram of the system principle of the present invention. Detailed Embodiments
[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0038] Embodiment 1. Please refer to Figure 1 , this application provides an intelligent control system for a solar power generation device, including an operating parameter acquisition module for the power generation device, a device status analysis module, a device anomaly analysis and processing module, a device normal analysis and processing module, a comprehensive analysis and processing module, and an intelligent control output module, and there is a one-way electrical connection between the above functional modules.
[0039] Power generation equipment operation parameter acquisition module, which is used to acquire the operation parameters of the solar power generation equipment corresponding to the power station. The acquired operation parameters include voltage, power consumption, current, and output power, and at the same time, the acquired operation parameters are transmitted to the power generation equipment status analysis module.
[0040] Power generation equipment status analysis module, which is used to identify the operation status of the solar power generation equipment according to the acquired operation parameters, generate a status identification result, and transmit the normal operation result in the status identification result to the equipment normal analysis and processing module, and transmit the abnormal operation result in the status identification result to the equipment abnormal operation processing module.
[0041] Obtain the solar power generation equipment and label it as i, and i = 1, 2,..., j, where j represents the number of solar power generation equipment. Then obtain the operation parameters of the solar power generation equipment, and at the same time obtain the corresponding output power Gi out , and the obtained output power Gi out is compared with a preset value, and the specific value of the preset value is set by the operator. If the output power Gi out is greater than the preset value, it means that the corresponding solar power generation equipment is operating normally, and a normal operation result is generated. On the contrary, if the output power Gi out is less than the preset value, it means that the corresponding solar power generation equipment is operating abnormally, and an abnormal operation result is generated.
[0042] Equipment abnormal analysis and processing module, which is used to analyze the obtained abnormal operation result. By analyzing the solar power generation equipment under the same conditions, determine the abnormal cause of the solar equipment, generate abnormal cause information, and transmit it to the intelligent control output module at the same time.
[0043] The solar power generation equipment corresponding to the abnormal operation result is obtained and recorded as the abnormal analysis equipment. At the same time, the power generation conditions corresponding to the abnormal analysis equipment are obtained and recorded as the conditions to be analyzed. And the operation status of all solar power generation equipment is obtained with the conditions to be analyzed as the standard. Specifically, here all solar power generation equipment corresponding to the same conditions to be analyzed are obtained. If there is solar power generation equipment corresponding to the abnormal operation result, the conditions to be analyzed are marked as abnormal conditions, and at the same time, abnormal condition information is generated. On the contrary, if there is no solar power generation equipment corresponding to the abnormal operation result, it means that the conditions to be analyzed are normal, and internal abnormal cause information is generated.
[0044] Suppose there is a power station composed of 10 solar power generation devices. One day, the output power of device 3 and device 7 decreased abnormally, and they were marked as devices for abnormal analysis. For device 3, the power generation conditions obtained were light intensity of 300 W / m², ambient temperature of 38 °C, tilt angle of the solar panel of 15 °, and wind speed of 5 m / s; for device 7, the power generation conditions were light intensity of 300 W / m², ambient temperature of 38 °C, tilt angle of the solar panel of 15 °, and wind speed of 6 m / s. Since most of the conditions were similar, the light intensity of 300 W / m², ambient temperature of 38 °C, and tilt angle of the solar panel of 15 ° were determined as the conditions to be analyzed. Taking these conditions to be analyzed as the standard, all 10 devices were screened, and it was found that device 1, device 4, and device 9 were also in the working conditions of light intensity of 300 W / m², ambient temperature of 38 °C, and tilt angle of the solar panel of 15 ° at the current moment. Further inspection found that the output power of device 4 also decreased abnormally. At this time, the system determined that the conditions to be analyzed were abnormal conditions and generated an abnormal condition information report:
[0045] Abnormal condition parameters: light intensity of 300 W / m², ambient temperature of 38 °C, tilt angle of the solar panel of 15 °;
[0046] Device numbers involved in the abnormality: 3, 4, 7;
[0047] Description of the abnormal phenomenon: Under this condition, the output power of the device is significantly lower than the normal level.
[0048] If the operating states of device 1, device 4, and device 9 are all normal during the screening process, the system will generate an internal abnormal cause information report, prompting an internal hardware inspection of device 3 and device 7, such as checking whether there are hidden cracks in the solar panel and whether the inverter is faulty.
[0049] Intelligent control output module, which is used to display the obtained abnormal cause information to the corresponding operator.
[0050] Embodiment 2, this embodiment is implemented on the basis of Embodiment 1, and the differences from Embodiment 1 are as follows:
[0051] Device normal analysis and processing module, which is used to analyze the solar power generation devices corresponding to the normal operation results. By analyzing the power generation and energy storage of the solar power generation devices, calculating the energy efficiency corresponding to the solar power generation devices, classifying the solar power generation devices secondarily according to the energy efficiency to obtain specific analysis information, and at the same time transmitting the secondary analysis signal in the specific analysis information to the comprehensive analysis and processing module, and transmitting the warning signal in the specific analysis information to the intelligent control output module.
[0052] Obtain the solar power generation equipment corresponding to the normal operation result and mark it as the normal power generation equipment. Then, obtain the discharge records corresponding to the normal power generation equipment, and at the same time obtain the discharge depth corresponding to the discharge records. Specifically, the discharge depth refers to the percentage of the electricity discharged by the battery within a certain period of time to its rated capacity. For example, for a battery with a rated capacity of 100 Ah, if 50 Ah of electricity is discharged, then the discharge depth at this time is 50÷100×100% = 50%. And obtain the discharge records corresponding to the abnormal discharge depth and mark them as abnormal records. Then, number the abnormal records as a, and a = 1, 2, …, b, where b represents the number of abnormal records. At the same time, classify the abnormal records a according to the discharge depth, and the specific classification method is: obtain the discharge depth corresponding to the abnormal record a, and match the discharge depth with the corresponding classification interval, and the classification interval represents different degrees of discharge depth. Organize the matching results to obtain the discharge classification information; for example, classify the discharge depth to obtain the shallow abnormal discharge depth interval (70% - 80%), the medium abnormal discharge depth interval (81% - 90%), and the deep abnormal discharge depth interval (91% - 100%).
[0053] Then, obtain the discharge classification information. At the same time, obtain any group of discharge classification information as the analysis target, obtain all the abnormal records within the analysis target, and the abnormal records obtained here are the abnormal records of the same type. And obtain the energy efficiency of the discharge depth corresponding to the abnormal records, where the energy efficiency refers to the ratio of the energy output during battery discharge to the energy input during charging. At the same time, calculate the average value of all the energy efficiencies within the analysis target and record it as the mean energy efficiency. Take the obtained mean energy efficiency as the standard energy efficiency of the analysis target, and calculate the mean energy efficiencies corresponding to all the discharge classification information by analogy;
[0054] Sort the obtained discharge classification information from largest to smallest. Here, from largest to smallest means sorting according to the discharge depth from largest to smallest. For example, sort from 90% (the largest) to 70% (the smallest). At the same time, generate the standard energy efficiency based on the mean energy efficiency corresponding to the smallest discharge classification information, and take the standard energy efficiency as the energy efficiency of the current normal power generation equipment. Then, compare the standard energy efficiency with the energy efficiency standard;
[0055] If the standard energy efficiency is greater than the energy efficiency standard, generate a secondary analysis signal, and at the same time mark the corresponding normal power generation equipment as the secondary analysis equipment. On the contrary, if the standard energy efficiency is less than the energy efficiency standard, generate a warning signal and transmit the warning signal to the intelligent control output module.
[0056] Comprehensive analysis and processing module, which is used to analyze the obtained secondary analysis signal, calculate the corresponding depth of discharge according to the standard energy efficiency of normal power generation equipment, generate depth of discharge information, and transmit the depth of discharge information to the intelligent control output module.
[0057] Obtain the normal power generation equipment corresponding to the secondary analysis signal and label it as n, where n = 1, 2, …, m, and m represents the number of normal power generation equipment. Then obtain the standard energy efficiency corresponding to the normal power generation equipment , obtain the rated power Qn corresponding to the normal power generation equipment n during the charging process rated , the charging power En in = V × Qn rated , the discharge energy En during the discharge process out = V × Qn discharged , where Qn discharged is the power discharged by the normal power generation equipment. Then according to the formula ;
[0058] At the same time, comprehensive calculation is carried out in combination with the coulomb efficiency of the energy storage system. The coulomb efficiency refers to the ratio of the output charge amount during the discharge process to the input charge amount during the charging process. Specifically , then judge the charging voltage and discharge voltage corresponding to the normal power generation equipment. If the two are the same, then according to the formula Calculate the depth of discharge DODn;
[0059] For example, in the case where the charging voltage and discharge voltage are the same, the energy efficiency = 80%, and the coulomb efficiency CE = 90%. Then according to the formula, the corresponding depth of discharge DoD = 88.9% is calculated.
[0060] If the two are different, then obtain the charging voltage Vn in and the discharge voltage Vn out , as well as the corresponding charging power and discharge power En in and En out , and substitute the obtained parameters into the formula Calculate the depth of discharge DODn, generate depth of discharge information at the same time, and transmit it to the intelligent control output module.
[0061] For example, if the energy efficiency = 75%, and the coulomb efficiency CE = 85%, where the charging voltage Vn in = 5V, and the discharge voltage Vn out = 4.5V, then according to the formula, the corresponding depth of discharge DoD = 88.9% is calculated.
[0062] Intelligent control output module, which is used to display the obtained depth of discharge information to the corresponding operator.
[0063] Embodiment 3. As the third embodiment of the present invention, the key lies in combining the implementation processes of Embodiment 1 and Embodiment 2.
[0064] Some of the data in the above formula are taken for numerical calculation with their dimensions, and the content not described in detail in this specification belongs to the prior art well known to those skilled in the art.
[0065] The above embodiments are only used to illustrate the technical method of the present invention and not to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical method of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical method of the present invention.
