System Control and Data Acquisition of University Photovoltaic Power Plant

The paper deals with design of System Control and Data Acquisition (SCADA) of Photovoltaic power plant FERIT 1, its configuration and connection with server unit for data archiving and removal approach by either android or PC devices. SCADA is developed according to ideas and need for scientific research of data generated by photovoltaic power plant built on the roof of the Faculty of Electrical Engineering, Computer Science and Information Technology Osijek in Osijek, Croatia. Designed system enables real-time analysis and of course subsequent time analyses based on storing data of high frequency measurement samples of photovoltaic (PV) power plant. The first part of the paper describes hardware components and system configuration and the second part deals with software background. Measurements of PV parameters and meteorological conditions are continuously performed, and these data are stored locally and instantaneously stored also on remote servers. Acquired measurement data is presented by graphics on developed web server platform. Developed SCADA presented in the paper is unique, adaptable open source which enables long-term performance of power plant and its components' function.
