Abstract


The smart grid has become the latest change direction in the development of the power system of the world today, however intelligent distribution network has become the focus of the study. Become the core content has been concerned in the distribution network automation in distribution automation development, feeder automation system, its requirements of feeder automation system can be achieved with electric power lines and fault status and fault status monitoring, control, protection, and automatic refactoring of the post-fault network online, near real-time closed-loop control. This paper presents the background smart protection technology master feeder protection based on the high-voltage circuit breaker terminal (FTU) FA (feeder automation) processing technology combined control strategies and methods to adapt to the development needs of today's feeder automation system and the future direction of development. The main focus of this article is in order to achieve feeder terminal (FTU) protection technology and master background FA (feeder automation) technology in the relative timing and functionality combined with feeder automation control strategy, content design three: 1) controller design for the circuit breaker feeder protection terminals (FTU). 2) on the communication network between the FTU and the master station background design, this article uses a GPRS wireless communications network technology. 3) the use of the C language design master background FA subsystem simulation to verify the feasibility of FA procedures. Core hardware design of Intelligent Protection feeder terminal unit (FTU), \CPLD peripheral logic circuit expansion capability, and provide a good interface between DSP and peripheral set with logic. Protection unit of software design, RTOS real-time operating systems thinking, this article transplant μC/OS- Ⅱ operating system to manage the entire system software running, a reasonable allocation of timing to achieve the accuracy of the time limits set forth to reach the high real-time . FA subsystem based GIS master background design using C development language to design the FA (feeder automation) function modules, geographic information subsystem GIS grid model was established based on the topological model FA program utilizes topology model fault diagnosis, fault isolation, and restore the power supply and other functions, and then through the simulation program to verify.
