光伏電池老化故障內(nèi)部參數(shù)變化規(guī)律的研究
[Abstract]:With the increasingly prominent ecological problems, the excessive consumption of oil and coal resources, more and more attention has been paid to new energy. Renewable new energy industry, represented by photovoltaic industry, has been developed rapidly. However, behind the rapid development, the research on photovoltaic cell fault is still in its infancy. The main faults of photovoltaic array include solar module cracks, hot spots and aging damage. The research of hot spot fault diagnosis has been developed to the level of fault location, however, the related research on aging fault diagnosis of photovoltaic cells is still rare in the world. The change of internal parameters and aging fault model of photovoltaic cells are still unsolved. In order to accurately establish the aging model of photovoltaic cells, the internal parameters of photovoltaic cells during aging were studied, and the variation of internal parameters of photovoltaic cells with aging process was revealed. It lays a sufficient foundation for the establishment of photovoltaic cell aging model. In this paper, based on the photovoltaic cell model and aging mechanism, the influencing factors of photovoltaic cell aging and the performance characteristics of photovoltaic cell aging are analyzed, and a platform to simulate the aging of photovoltaic cell is built. The voltage and current acquisition module is designed to collect the I V characteristic curve of photovoltaic cell. After data processing and data filtering, the collected data are brought into adaptive chaotic particle swarm optimization algorithm for parameter identification. The algorithm has the advantages of fast optimization and accuracy. The results of parameter identification are as follows: under this condition, the internal parameters of photovoltaic cells (photogenerated current, diode reverse saturation current, diode influence factor, series resistance and parallel resistance) are the actual values of the internal parameters (photogenerated current, diode reverse saturation current, diode influence factor, series resistance and parallel resistance). Finally, in order to reveal the variation of internal parameters in the aging process of photovoltaic cells, outdoor experiments were carried out under different aging degrees and different external conditions, and more than 150 groups of voltage and current values were identified. The identification results of internal parameters under different aging degrees and different external conditions are fitted, and the variation of each parameter with aging degree, irradiance and temperature is obtained, and the prototype of the aging fault model of photovoltaic cells is established. The research in this paper not only does enough preliminary work for the accurate establishment of photovoltaic cell aging model, but also can apply the results to the engineering practice of aging fault diagnosis through the output characteristics of photovoltaic cells.
