The Research Of Remote Wireless Monitoring Technology Based On Wind-Photovoltaic Complementary Power Station

With the rapid development of power generated technology of wind and solar,off-grid wind-photovoltaic complementary power station which is economic, green energy, hasbeen used more and more widely used as a power supply. Meanwhile, The remote monitoringproblem of the faraway regional power station which power grid cannot cover, has beenattached to more and more importance. To evaluate the running state of the whole and each partof the wind-photovoltaic complementary power station of wind-light complementary powerstation, it is essential to measure several of parameters of wind-photovoltaic complementarypower station, and transfer the data to the remote server, when it is necessary, to controlequipment remote. The thesis proposeds a wireless monitoring system, which bases on thetechnology of wireless area network and GPRS, completes the remote inspecting、measuring.The paper introduces the operational principle of wind-photovoltaic complementarypower station, proposes the hardware and software design of detection and control system ofwind-photovoltaic complementary power station, With the ultra-low power consumptionMSP430F149as its core, the data acquisition module uses on chip ADC combined with signalconditioning circuit to complete the information collection.of the voltage, current, temperatureand power station running state and so on. Using the wireless self-organizing Zigbee module totransfer data to the network coordinator, the network coordinator, which its core is STM32F103,transfers data to the remote server by using GPRS module.Remote monitoring softwareLABVIEW designs the front panel, writes the display program, and database storage accessprocedures. The software realizes the function of showing real-time parameters of thewind-photovoltaic complementary power station and saving data function. Tested in applicationshows, the remote monitoring system reaches the function of of data acquisition, transmission,display and storage. The data acquisition node consumes little current, the net works stability,which meets the design requirement.
