Предложена новая Simulink-модель фотоэлектрического модуля, ориентированная на использование стандартной библиотеки элементов систем электроснабжения SimPowerSystems из программного пакета MatLab/Simulink. Модель позволяет изменять значения солнечного излучения для каждого фотоэлемента модуля, а также получать расчетные значения напряжений и токов на выходе фотоэлектрического модуля. С помощью модели можно выполнять имитацию затенения отдельных фотоэлементов модуля. Разработанная Simulink-модель функционирует на основе известной экспоненциальной зависимости, описывающей вольт-амперную характеристику фотоэлектрического модуля, и учитывает реальную схему модуля с обходными диодами. Последовательное сопротивление фотоэлектрического модуля рассчитывается на основе разности между его экспериментальными и теоретическими вольт-амперными характеристиками для условий, близких к нормальным. Simulink-модель модуля SF-P672300 содержит 72 нелинейных элемента, реализованных на основе управляемых источников тока и соединенных последовательно. В модели решены проблемы устойчивости алгоритма расчета алгебраических циклов за счет введения параметров ограничений по напряжениям и токам. Экспериментальные исследования для полностью освещенного и частично затененного модуля SF-P672300 показали, что максимальная относительная погрешность разработанной Simulink-модели не превышает 15 %. Приведены экспериментальные и теоретические вольт-амперные характеристики модуля SF-P672300 при полном освещении и частичном затенении. Предлагаемая Simulink-модель может быть использована на этапе как проектирования, так и эксплуатации фотоэлектростанций с целью имитации и анализа факторов, влияющих на их работу.</p></abstract><trans-abstract xml:lang="en"><p>The relevance of research is caused by the increase of the number of photovoltaic power plants in the Republic of Belarus and, accordingly, the need to solve problems of diagnostics of photovoltaic modules. A new Simulink model of a photovoltaic module focused on using the standard SimPowerSystems library of power supply system elements (a part of the MatLab/Simulink) is proposed. The model allows altering solar irradiation values for each solar cell of the module. The use of the model also makes it possible to obtain calculated values of voltages and currents at the photovoltic module output. In addition, the model provides the simulation of individual solar cells shading in the module. The developed Simulink model operates on the base of a well-known exponential dependence describing the volt-ampere characteristic of a photovoltaic module, and also takes into account the real circuit of the module with bypass diodes. The series resistance of the photovoltaic module is calculated by the subtraction between its experimental and theoretical volt-ampere characteristics for conditions that are close to normal. The Simulink model of the SF-P672300 module contains 72 nonlinear elements implemented on the basis of controlled current sources and connected in series. The model solved the problems of the algorithm stability for calculating algebraic cycles by introducing constraint the current and the voltage parameters. Experimental studies for the fully illuminated and partially shaded SF-P672300 module have demonstrated that the maximum relative error of the developed Simulink model does not exceed 15 %. Experimental and theoretical current-voltage characteristics of the SF-P672300 module under full illumination and partial shading are presented. The presented Simulink model may be used both at the design stage and at the operation stage of photovoltaic power plants in order to simulate and analyze the factors that affect the operation of them.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Simulink-модель</kwd><kwd>фотоэлектрический модуль</kwd><kwd>вольт-амперная характеристика</kwd><kwd>SimPowerSystems</kwd><kwd>имитационное моделирование</kwd><kwd>частичное затенение</kwd><kwd>обходной диод</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Simulink model</kwd><kwd>photovoltaic module</kwd><kwd>volt-ampere characteristic</kwd><kwd>SimPowerSystems</kwd><kwd>simulation modeling</kwd><kwd>partial shading</kwd><kwd>bypass diode</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Pandiarajan, N.
