Abstract


As an important direction of future power system, Microgrids could improve power supply reliability and power quality; make better use of renewable energy. The communication system is essential to Microgrids by transferring sampled data and control information, while it still needs further development to meet the incoming demands of Microgrids.By reading a large number of domestic and foreign literature. Microgrid demonstration projects all over the world are reviewed, some knowledge about the the Microgrid data acquisition system are summarized. On this basis, this paper proposed a data acquisition system with power quality detection function, software is based on LabVIEW, hardware is based on NI data acquisition hardware and the WAGO PLC module hardware, this system has facilitated the study of the Micro-grid. Real-time analytical software of voltage deviation, frequency deviation, grid harmonics, and three-phase unbalance are also buid on LabVIEW. The system has data acquisition, storage, data query, analysis and management capabilities. By using Modbus protocol, LabVIEW software have the ability to access data from the PLC, to further improve the data acquisition system.
