Design of Three Phase Network Parameter Monitoring System Based on 71M6513
In this paper, the design process of Three Phase Network Parameter Monitoring System is analyzed and the overall research scheme and design idea of the system are expounded. This paper mainly studies how to improve the accuracy of input voltage and current. The front-end voltage decreasing, current dropping circuit and remote data transmission circuit are designed. The programs of the data acquisition and calculation are made, real-time detection of power network parameters, energy calculation and the remote data transmission are achieved. Based on. Net platform, the host computer software is designed to receive the data and store them in the database, the mean value of power and energy parameters are calculated by the day, the week and the month, which are available to the user for inquiry. Many parameters such as three-phase voltage, three-phase current, frequency, active power, reactive power and voltage harmonics, can be detected by the system, which will provide a reliable basis for power quality analysis.
