Description

Technical Field

[0001] The present application belongs to the field of photovoltaic power generation technology, and specifically, relates to a method and system for processing outdoor operation data of photovoltaic modules. Background Art

[0002] Photovoltaic modules are the core components of photovoltaic power stations. Their performance has a key impact on the revenue of the power station. It is necessary to clearly evaluate their power generation performance in order to achieve the design, management and operation of photovoltaic power stations, improve power generation efficiency, and increase the investment return rate of photovoltaic power stations. Methods for evaluating the performance of photovoltaic modules include indoor measurements and outdoor measurements. Indoor measurements require the use of a solar simulator and the construction of a stable test environment. The stable test environment requires that the solar simulator, photovoltaic modules, and ambient temperature are all at 25±2℃, and the light intensity of the solar simulator is set to 1000W / m 2 At the same time, the spectrum mismatch of the solar simulator is between 0.75 and 1.25 relative to AM 1.5G, the light non-uniformity irradiated on the surface of the component is within ±1%, and the stability of the light intensity during the entire test process is less than ±1%. The specific experimental process in the industry refers to the maximum power test section of IEC 60904-9 and IEC 612152.

[0003] The use of solar simulators for evaluating the performance of photovoltaic modules indoors has good repeatability and high accuracy, but the photovoltaic modules running outdoors need to be disassembled and transported to the indoor laboratory, which consumes a lot of manpower, material and financial resources. In addition, the photovoltaic modules may be damaged during transportation. At the same time, the most important thing is that the test results mainly represent the laboratory test results, which are only of reference significance for the actual performance of photovoltaic modules in outdoor operation, and are not the performance parameters of the modules under real operation. Therefore, how to obtain the real operation data of photovoltaic modules through outdoor measurement means is crucial to accurately evaluate the performance of photovoltaic modules and to reasonably invest in the construction and operation of photovoltaic power stations.

[0004] Outdoor testing requires testers to carry portable test instruments or install a complete set of data acquisition and transmission systems on site to collect data. Compared with indoor testing, outdoor testing is more convenient and more economical. However, at the same time, under outdoor conditions, due to the random changes in the outdoor meteorological environment, the photovoltaic module performance data collected through outdoor measurements may contain more environmental noise, thus affecting the accurate evaluation of photovoltaic module performance.

[0005] According to measurement theory, the magnitude of measurement repeatability reflects the degree of change of random errors in the measurement process. It is generally believed that data collected under measurement repeatability conditions have good stability. For indoor measurement of photovoltaic module performance, the measurement environment is controllable and stable, and it is easy to obtain data that meets the measurement repeatability conditions. However, at this stage, in outdoor measurement of photovoltaic module performance, the definition of outdoor measurement repeatability conditions is still unclear. Summary of the invention

Figure 2 It shows that nearly 32% of the data on a certain day do not meet the outdoor measurement repeatability conditions of PV modules and should be eliminated.

[0072] For example, the repeatability of the test results of the target photovoltaic module under the outdoor measurement repeatability condition is quantitatively expressed by a statistic that characterizes the degree of data dispersion. If expressed in the form of repeatability standard deviation, the absolute repeatability of the test results of the target photovoltaic module under the outdoor measurement repeatability condition is
