Modelling of a Multipurpose Photovoltaic Generator Block Using ATP-EMTP

摘要： One of the major references to deal with electromagnetic transients is the ATP-EMTP program whose associated tools, ATPDraw (a graphical interface) and MODELS (a programmable language), have pushed its use to other electrical system analysis. In this context, this article aims to show the development of a computational block to represent the photovoltaic generator in ATP, with its respective mask and configuration in ATPDraw. Starting from the classical mathematical foundation, a photovoltaic module is developed from data available in manufacturers’ manuals. The ideality equations are then modified to attend different purposes: applying new values of temperature and irradiation, choosing series and/or parallel association of modules, including different values of series and parallel resistances. The final multipurpose photovoltaic generator is validated by comparison of its results with those found in the related technical literature.
