GSM-Based Malfunction Automatically Detect And Automatic Meter Recording System Of Transformer Adaptable To Low-Voltage Distribution Networks

Electric distribution automatic system is given more attention as an major aspect of the electric power system automatic project. The distribution system in China has developed rapidly recent years, the best request of development of electric industry is the intelligent of synthetically functions about electric power measure, charge control, electric power attempering, malfunctions check and malfunction close off. The low voltage distribution net orients to the vast low voltage customers that are in great number and disperse in a broadness load center. It must be a tendency that we should not only program the distribution net synthetically but also use and manage them synthetically. The automatic meter recording(AMR) system is the technology guarantee for the commercialization of the electric power system. Through the AMR system power company can get data of the consumer's power meter remotely. AMR can also give out more information such as the real power consumption data of every kind consumers and the power transmitting data of each line. Based on the data, AMR can also provide many advantage applications. It can calculate the power lose rates in vary time and the perk requirements of the consumers. This information will help the power distribution department to reduce the loss and will help the power distribution department to reduce the loss and will improve the oecumenical characteristic of the power system.Firstly, the thesis narrates on the significance of the monitoring and control to the low voltage distribution network. Then the thesis analyzes about the feature of the network itself and introduces the way of communication of AMR and the monitoring and control to the low voltage distribution network. Secondly, the thesis gives the design of the whole system frame and gives a more detailed depiction to communication scheme and malfunction automatically detect. AMR system can be used as a part of distribution automation system. It has important signification in load forecast and economic distribution. This article proposes a malfunction automatically detect and automatic meter recording system of transformer adaptable to low-voltage networks based on GSM. It aims to collect working data of voltage, current and power through, real time judges according to various malfunction characters, run information and malfunction information can use wireless communication integrated circuit to transmit electricitydate point to point based on GSM network, electrician can easily monitor and maintenance. This system can improve the automation of low distribution networks, improve the efficient of collection to send and dispose of data, and real time about monitor of malfunction.
