Design Of Photovoltaic Power Generation Wireless Monitoring System

With the increasing depletion of fossil fuels and people's concerns about the environmental problems caused by burning, it is urgently necessary to develop new energy. In the Twelfth Five-Year Plan, increasing investment in new energy is clearly put forward, especially in photovoltaic industry. With the support of a series of national policy and the large numbers of funds invested by the country, Distributed PV market will be rapidly developed. However, there is not a perfect system to realize the function of remote power monitoring and online trading of Distributed PV currently. For this reason, this paper designs a kind of remote power monitoring system for PV to realize remote power monitoring and online trading. Design contents of the system are as follows:Through reading a lot of literature at home and abroad and researching and studying existing wireless communication mode deeply and thoroughly, propose a kind of photovoltaic wireless monitoring system, which based on two kinds of wireless communication technology, and realize the remote release of the system.It can use intelligent watt-hour meter as the acquisition terminal of electric signal, and transport electric signals collected to through 485 bus, then collect the signal by ZigBee Terminal and send it to coordinator gateway that regards ARM9 MCU as its control center. At last, it transfers remotely the data from gateway by using GPRS Technology and TCP/IP protocol.By using LabVIEW and some related modules and writing a strong visual PC interface with imagery programming language, it is able to display, store and inquire the quantity and energy of electricity of the system. The system interface is sent to the network transmission on the Internet by WEB Publishing Technology, which realizes the remote operation and access to the system.The system takes full advantage of ZigBee and GPRS Communication Technology, realized wireless collection, transmission, display and storage of electric signal. The system interface is friendly, easy for user to operate, which can offer some valuable reference for the Monitoring Research of Distributed PV system.
