Distribution Transformer Running State Remote Monitoring System Disquisition

Distribution transformer is the most important electric apparatus in the distribution network, whose running state relates the stability of distribution network. The transformer monitor terminal unit, naming TTU, is an important part of distribution automation system, and guarantees the security of distribution automation system.Based on the study of the principle and the development of transformer monitor terminal unit at home and abroad, extensive market research and consideration with the demands of the client, a distribution transformer running state remote monitoring system is proposed and realized by use of the single-chip PIC18F458 and GSM communication technology. The main station management system is designed with the Visual C ++6.0 and MySQL database platform, whose software interface is handsome, simple and convenient.The paper introduces the background of study, the development of TTU, the aim and significance of this research project at first; In the second, it introduces the design thought of distribution transformer running state remote monitoring system, puts forward the total design scheme of the hardware circuit and software system, which decides the function and the capability of this device. Then, the theory of signal data acquisition is introduced and the calculation of electrical parameter is mainly described. The hardware configuration of the device is given, including the important parts selection and the anti-interference design of the hardware. The software structure of distribution transformer running state remote monitoring system is presented in detail, including the background interference management system of monitoring center and anti-interference design of the software. Finally, the summarization and prospect of this study are proposed.Distribution transformer running state remote monitoring system can be used as a part of power usage management system or distribution automation system. There is important signification for dispatching and distributing load. It will be of great benefits to society and economy.
