The Design Of Remote Monitoring System Of Distribution Transformer Based On GPRS

The distribution transformer is the power equipment that the directly distribute the electrical energy to the low voltage user. Its running data is the important constituent of foundation data in the entire distribution. network. The requirement of the user is more and more highly for the power supply quality (for example: voltage qualified rate, frequency and so on) and the power supply reliable in the city and countryside electrical network, along with the social progress, the economical development and the enhancement of the people's living standard.GPRS, General Packet Radio Sevice, is a new, high efficient and low cost radio statistics service developed from GSM. The principle, network structure, network hierarchical mode and application of GPRS are introduced in this thesis. And, its future development is forecast.Considering the requirement of data transmission reliability and real-time in distribution transformers, the remote monitoring system of distribution transformer based on GPRS is designed. It changes choke point of the communication transfer between the master station and terminal units. This new system characterizes by higer speed, greater data input/output and well satisfies the demands for reliability and real-time of the data communication. This system enables the operating staff to understand the distribution situation on time.
