Research Of The Local Measurement And Control Unit Of Substation Integrated Automation Based On ARM Embedded Technology

With the rapid development of Economy and Power Industry, the power level of automation and information systems is increasingly high requirements. Substation system as a vital link directly affects their level of automation of the safe and stable operation of power grids, Substation integrated automation system has been so rapid development and marketing to become an important basis for measuring the level of electricity enterprise automation. And a secure and reliable network communications technology is the fundamental guarantee for realizing substation integrated automation system.Substation transmission and distribution system is the pivotal link; it is an important part of the power system. As the substation integrated automation system is very important to the control unit is an integral part of It directly affects the performance of the substation integrated automation system overall efficiency, and safety of operation.With the increased complexity of grid voltage and the power transmission and distribution capacity and the increasing radius, using the traditional first and second substation equipment has become increasingly difficult to satisfy: "reduce engineering costs , improve the safety and economic operation substation level, "The requirements in these two areas. Therefore, it is essential to research and development of computer technology to the voltage level of substation integrated automation systems, to replace or upgrade traditional substation equipment.Based on the current substation integrated automation system technology for reference, Research and proposed a high-performance embedded microprocessors based on ARM core and the Embedded Real-Time Operating System Transformation Integrated Automation Control Unit to stop now. Various modes of text from the current substation integrated automation system, combined with the trend of the development of computer technology; the control unit is a detailed account of the Principles and to the composition and characteristics. Samsung to focus on the analysis of the company's 32-bit embedded microprocessor core for embedded S3C4510B network system software and hardware design, the hardware schematic diagram; For the system's key technologies : Transplant UC/OS-II operating system, This paper madesoftware system design issues, and detailed exposition, and the associated design process.Embedded is a new substation integrated automation and control unit to provide a stronger and faster communication speed the handling capacity, It will enhance the application of substation integrated automation system communication capability. Substation integrated automation system but also higher reliability, economy has a strong edge.
