Data Acquisition And Processing

Ethernet based on TCP/IP is a standard open network, which promotes the development of data acquisition in the direction of network. Data acquisition and processing systems connected by Ethernet make the data acquisition terminals (lower computer) and processing control center (upper computer) from integrated to discrete. Separate data acquisition terminals can realize miniaturization and modularization and increase the flexibility of the application. A new type, low cost, high precision data acquisition terminal based on ARM processor was designed for solving the problem of complicated structure, big volume and high cost of traditional data acquisition system. Combined with the technologies of network communication, a data acquisition PC system based on virtual instrument technology was designed by LabVIEW.

This paper centers on the design and installation of a robust photovoltaic (PV)-based microgrid data acquisition system (DAS) that can monitor different PV systems simultaneously. The PV-based microgrid consists of three solar systems: off-grid, hybrid and grid-assisted systems, each with 3.8 kWp located at SolarWatt park, Fort Hare Institute of Technology (FHIT), South Africa. The designed DAS is achieved by assembling and connecting a set of sensors to measure and log electrical and meteorological parameters from each of the three power plants. Meteorological parameters use a CR1000 datalogger while the electrical output parameters use a DT80 data logger. Calibration was done by voltage signal conditioning which helps to reduce errors initiated by analogue signals. The designed DAS mainly assist in assessing the potential of solar energy of the microgrid power plant considering the energy needed in the remote community. Besides, the simultaneous monitoring of the three systems ensures that the outdoor operating conditions are the same while comparing the logged data. A variable day and a week, data were used to verify the reliability of the system. The back of the array temperature was observed to be 42.7 °C when solar irradiance was 1246 W/m2. The ambient temperature and relative humidity were obtained at 21.3 °C and 63.3%, respectively. The PV current in all three systems increases with the solar irradiance and is highest around midday. The results obtained show that the designed DAS is of great interest in PV system developments.
