Title: Emulator of PV Panels for Laboratory Studies
Keywords: PV emulator, power amplifier, LabVIEW environment

Abstract: The paper presents the realization of emulator of photovoltaic (PV) panels for laboratory studies in the Technical University of Sofia. First, the different possibilities for realization of such emulator are reviewed shortly. Then, is presented the emulator created in the Department of Electrical machines using power amplifier, controlled by PC. The PV emulator's control is implemented in the LabVIEW environment for simulation of the PV panel's behavior. For this purpose, is used an appropriate mathematical model of PV panel, based on single diode equivalent scheme. The model's equations are programmed in the LabVIEW environment and the possibility to obtain different I-V characteristics, corresponding of different meteorological conditions, is verified. Finally, the correct operation of the created emulator is verified and illustrated with different operation points that follow the I-V characteristic of the panel.
