The voltage harmonic distortion of 10 kV access point in charging station with different permeability is studied, the total harmonic distortion curve of voltage is obtained, and the comparison and analysis are carried out. The overall scheme of monitoring system for charging station of electric vehicle is designed. The overall structure of monitoring system of charging station is analyzed, and the function requirement of monitoring system is analyzed, and the communication network of monitoring system is designed. The data flow direction of charging station monitoring system and the data operation in each stage are studied. On the basis of the above research on the influence of electric vehicle charging on power grid harmonics, a monitoring system scheme including three charging modes is studied. The power quality monitoring, including harmonics, is brought into the design scheme to make up for the deficiency in the function of the current charging station monitoring system, and the subsystem is divided according to the difference of the monitoring function. Finally, The function design and software realization of each subsystem are studied. The software is designed based on LabVIEW platform, the function of user management system is analyzed, the user information is managed by access database, and the software is designed and implemented. The information exchange process, common anomalies and fault types during charging are studied, and the design of charging monitoring system is completed, and the power exchange flow is analyzed, the whole life cycle management of power battery is incorporated into the system design, and the ladder battery is utilized. The software design of the power exchange monitoring system is completed, the function of the power quality monitoring system is studied, and the adjustment and control strategies for several common indexes are studied to complete the overall design of the power quality monitoring system. The software program of the common power quality index is realized and simulated function test is carried out, the functional requirements, abnormal and fault types of distribution monitoring are studied, the software design of distribution monitoring system is completed, and the functional requirements of security monitoring system are studied.
