Design Of Distributed Building PV Power Station Monitoring And Controlling System Based On The Internet Of Things

Solar photovoltaic power generation system is an important way for the use of solarpower generation, and the fixed the photovoltaic system can not guarantee the sunlightperpendicular irradiation,according to the lowness of the solar energy utilization efficiency;At present, building photovoltaic power plants is the trend of a solar photovoltaic systemapplications and development, and the scale of the region have also expanded; Monitoring ofdistributed photovoltaic power plants has complex and high cost with wiring cable way, evenif using wireless means there are also the shortcomings of high cost and power consumption.For the above, this paper designed a low-cost, high-efficiency system of automatic grouptracking, monitoring and management for distributed building photovoltaic power plantsbased on the Internet of Things technology,to finish group controlling and digital regulationof the building photovoltaic power plants.This paper applies to Qiqihar University and Solar Energy Research Institute ofZhongshan University Joint construction of distributed building photovoltaic power plants inthree campuses of Qiqihar University. First,it elaborates developing status of the buildingphotovoltaic power plant and monitoring and controlling management technology,and appliesthe Internet of Things technology to the significance of the building photovoltaic powerplant.Second, according to the actual application requirements based on three-levelarchitecture of the Internet of Things technology and the principles and methods of automatictracking,it builds the overall program of monitoring and management system for buildingphotovoltaic power plants based on Internet of Things technology. Again,improving for thelack of monitoring and managing of photovoltaic power plants at home and abroad,systemdesigns a building photovoltaic power plants automatic group tracking and controlling andmanaging system,based on three frameworks of perception layer, transport layer andapplication layer in the Internet of Things,1、In the perception layer,system used as the core chip of ZigBee JN5139and drivecontroling TB6560HQ and so on,and designed building photovoltaic power plants operatingparameters of information collection and transmission and monitoring and buildingphotovoltaic power plants automatic group tracking and controlling system based on ZigBeewireless network.. System completed design of optical tracking transmitter and ZigBee terminal collecting and controling nodes and design of automatic group tracking and controlling andcollecting program in the ZigBee network,and the distribution network of the ZigBeenetwork、data acquisition and transmission and so on.2、In transport layer and application layer,system designed regional monitoring andmanagement module base on ZigBee wireless sensor network and remote access module withC/S mode by the Internet, the regional monitoring and management module achievesmonitoring and real-time displaying to monitor operating parameters information ofdistributed building photovoltaic power plants,and the remote access module supports accessoperating parameters information of distributed building photovoltaic power plants andapplication.Finally, constructing system debugging and experimental platforms is to test the systemfunctions.the test of system function shows the system of automatic group tracking andcontrolling works normally and collection and transmission of real-time datas in the ZigBeenetwork，and the efficiency of solar power generation is to30%above; In the transport layerand application layer the remote access module can achieve the operating datas of distributedPV power plant by Internet technology. The test results show that the design of system meetsthe expected demand, and has the value of development and application.
