The Design Of Remote Control System For Electricity Distribution Network Based On GPRS

With the high-speed development of economy and science technology , the demand of industry and resident for power supply quality is higher and higher . It is more and more important to improving power supply quality and reducing the time of power cut. The Automation System of Power Supply comprehends modern electricity technology, communication technology , internet technology and electric power equipment.The thesis puts forward in-depth analysis on the application characteristics and requirements on Low-voltage electricity distribution network ,and it explains the design scheme of the system . The specific implementation, which is composed of software and hardware, is brought forward. Base of several arithmetic, trouble-location and network reconfiguration put into practice.The embed terminal is include in Micro Processor Unit MCF5272 which is the core of hardware platform, and two peripheral interface such as RS232 serial port interface is essential for communication. The cms91 GPRS module of The Cellon Company is use to go online by wireless.The control center use industry control PC,and it can go online by special net.The software platform of embedded terminal is implemented with uClinux which is diminished from standard Linux. With the support of PPP,it can go online with GPRS module by dialing. The control use window2000 operation system.The function of the system is implemented by application communication software. The control center and embedded terminal use communication functions based on the popular BSD sockets which is supported with both Windows and Linux.The application layer use the 101 Protocol. Then, the thesis puts forward the arithmetic for trouble location and network reconfiguration,on the application characteristics and requirements on Low-voltage electricity distribution networkBased on the analysis of the automation system of electricity distribution network, the paper present improvement against the limitation of existing system. The innovation of this system consists in construction and function integration, the trouble location arithmetic and the reconfiguration decision-making.It can be consulted and popularized by homogeneous system.
