Description

Technical Field

[0001] The present invention relates to the technical field of monitoring wind-solar integrated power generation systems, and in particular to artificial intelligence monitoring of wind-solar integrated power generation systems based on multi-dimensional sensor data. Background Art

[0002] In today's global energy landscape, with the increasing depletion of traditional fossil energy and the increasing awareness of environmental protection, the development and utilization of new energy has become the focus of attention of countries around the world. As the most promising renewable energy sources, wind and solar energy account for an increasing proportion of the energy structure. However, wind and solar power generation systems are greatly affected by natural conditions (such as irradiance, wind speed, wind direction, etc.), and their output power has significant intermittency and uncertainty, which poses a challenge to the stable operation of the power grid and the effective management of energy.

[0003] Traditional wind and solar power generation monitoring systems often rely on single sensor data, such as monitoring solar power generation efficiency only through irradiance sensors, or monitoring wind power generation status only through wind direction and wind speed sensors. This monitoring method is difficult to fully and accurately reflect the actual operating status of the system. In addition, these systems usually lack intelligent calibration and fault prediction capabilities, resulting in delayed equipment maintenance, reduced operating efficiency, and even possible safety accidents.

[0004] With the rapid development of artificial intelligence technology, its advantages in data processing, pattern recognition, and predictive analysis have provided new possibilities for the intelligent monitoring of wind and solar power generation systems. By integrating multi-dimensional sensor data, such as irradiance, wind direction, wind speed, etc., combined with a remote monitoring platform, real-time monitoring and intelligent analysis of key indicators such as instantaneous power of wind power generation and solar power generation can be achieved. This can not only improve the accuracy and comprehensiveness of monitoring, but also realize intelligent evaluation of the operating status of equipment through mining and learning of historical data, timely discover potential faults, and provide a scientific basis for equipment repair and maintenance.

[0005] Against the backdrop of increasing uncertainty in the current geopolitical situation, strategic competition in the global new energy industry is becoming increasingly fierce. Improving the operating efficiency of wind and solar power generation systems, reducing maintenance costs, and extending equipment life are of great significance to enhancing the competitiveness of the country's new energy industry. Therefore, the development of an artificial intelligence monitoring wind and solar integrated power generation system based on multi-dimensional sensor data has become a technical problem that needs to be solved urgently in the field of new energy.

The working process of solar energy intelligent calibration is as follows; S201. When the power generation system is initially installed at the factory, start solar energy intelligent calibration; S202. On a normal sunny day, obtain the curve graph showing the variation of the instantaneous power of solar power generation with time during this period through the management center , and calculate the total power generation of solar energy during this period ; S203, Record the real-time sunlight intensity with an irradiance meter and plot the real-time change curve of the solar radiation power during this time period ; S204, according to the real-time change curve of solar radiation power and the curve graph of the instantaneous power of solar power generation changing with time , determine the sunshine intensity interval of solar energy , and draw the curve of the power of the solar cell changing with the sunshine intensity ( I ); S205, according to the variation curve of the power of the solar cell with the sunlight intensity ( I ), use the formula , where ζ is the efficiency of the solar cell, to calculate and evaluate the relationship curve of the power generation efficiency of the solar cell varying with the sunlight intensity and the variation curve of the power generation efficiency of the solar cell ; S206, according to the solar cell power generation efficiency change curve and the solar cell power change curve with the sunlight intensity ( I ) to evaluate the length of the effective sunshine time period within a day ; The specific method is that when it is monitored that the efficiency = 0 or the curve of the instantaneous power of solar power generation changing with time = 0, the corresponding time period is an invalid time period, and the remaining time periods are counted as valid time periods ; Alternatively, monitor the real-time change curve of the solar radiation power when = 0 The critical value is defined as the sunshine intensity threshold for operation at this location , and only the sunshine time period above the threshold is the effective sunshine time, and the length of the time period is denoted as ; Meanwhile, within the effective sunshine time period determined according to the previous evaluation calculate the evaluated average solar cell power generation and the average sunshine intensity and use the relationship curve of the solar cell power generation efficiency varying with the sunshine intensity within the effective time period or the curve of the solar cell power generation efficiency variation to calculate the average power generation efficiency within this time period ; S207. When it is monitored that the maximum sunshine intensity exceeds the previously calibrated range, the statistical time period will be intelligently extended, and the above S201 - S206 process will be repeated to relearn and statistically analyze the power change curve of the solar cell varying with the sunshine intensity within the new time period. The relationship curve of the power generation efficiency of the solar cell varying with the sunshine intensity and the average power generation efficiency ; S208, by monitoring the relationship curve of the power generation efficiency of the solar cell varying with the sunlight intensity and the average power generation efficiency , the reference value range is defined as follows [ , ]; Among them, is the average power generation efficiency, is the standard deviation of the power generation efficiency of the solar cell varying with the sunlight intensity. Therefore, this interval is defined as the start-up calibration efficiency reference interval after the system actually operates at a certain location, that is, the normally measured power generation efficiency will be within this interval; According to the reference interval of solar power generation efficiency and in combination with the real-time change curve of the measured solar radiation power , the following calibration reference interval of the real-time solar cell power is correspondingly given: [ , ]; Among them, and are respectively the average power of solar power generation and the standard deviation of power fluctuation within the statistical sunshine intensity range.
