Change Based On The Gprs Wireless Communication Technology With Real-time Management System

Distribution transformers face to customers directly, its operation state is the important component of safe economical operation of the whole distribution network. With the extensive development of automatic construction of distribution, managing system of distribution transformer has turned into one of the important components of the automated system of the distribution.Considering the characteristics of distribution transformers, a system based on GPRS networks is put forward by taking a practical managing system of distribution transformer as an example. It utilizes the direct connection between GPRS network and Internet, setting a server in Internet, which takes charge of the transfer of the communication of the master station and the terminal units. This new system, which is characterized by higher speed and great data throughput, well satisfies the demands for reliability and real time of the data communication.This paper simply introduced the constitutes, functions and specialties of the managing system of distribution transformer. The automatic supervise and control system based on GPRS technology. The emphases of the paper are the device of terminal unit. The hardware design of distribution transformer terminal unit (TTU) is described in details, as well as the protocol between TTU and the master station. The design of master station and database is also described.The local running outcome and peculiarities of the managing system of distribution transformer based on GPRS technology is greatly perfection. All of this is evidence that it' s advisable to use GPRS in power system. The research about application of GPRS technology has profound theoretic andpractical significance.
