Modeling And Monitoring System Design For Wind And Solar Storage Charging Station

With the development of the electric vehicle market and the promotion of the national renewable energy consumption policy,combined with the regional characteristics of Inner Mongolia and the advantages of scenery resources,the construction of the wind wind electric vehicle charging station is imperative.The operation reliability and power quality of the charging station are the primary requirements of users.Modeling and simulation of the photovoltaic charging station is an important basis for monitoring the status of the charging station and achieving efficient management.Real time monitoring of the operation status and key parameters of the photovoltaic charging station is an effective means for effective monitoring of the charging station.On the basis of modeling and simulation of the charging station,this thesis constructs an online monitoring system based on CAN-GPRS for the off grid wind/solar storage and charging station,which provides guidance for the construction of the charging station.The specific work is as follows:1.The research background and research status at home and abroad of online monitoring of wind and solar storage and charging power station are compared and summarized,the significance of building the monitoring system is demonstrated,and the specific research contents and methods are proposed.2.According to the structural characteristics of the off grid charging station for wind/solar storage electric vehicle,determine the monitoring points of each sub module of the charging station,model each sub module in Matlab/Simulink environment,build a model of the charging station for wind/solar storage electric vehicle,and carry out simulation.Compared with the actual power station operation data,it shows that the model can correctly simulate the operation state of the charging station and verify the accuracy of the system model.3.In combination with the actual monitoring needs,a set of off grid wind solar electric vehicle charging station online monitoring system is designed.Network each sub module of the monitoring system of the off grid wind solar storage electric vehicle charging station,and determine the corresponding sensor types and parameters;CAN bus is used to realize data transmission in the station;Data transmission between stations based on GPRS wireless transmission mode;Finally,the collected data will be transferred to the background to achieve centralized and decentralized monitoring,laying the foundation for subsequent research.4.For the use scenario of online detection system,a set of wind and rain storage online monitoring software system is designed.The system uses Java Script based vue and EChart for front-end design,Python based Sanic for back-end design,and My SQL for database design.The monitoring system not only can normally monitor the real-time operation parameters of the power station,but also has the functions of alarm and history recording.And a set of multifunctional APP for electric vehicle users is designed to provide services for users’ charging decisions.
