Design of advanced RTU in dispatching automation of electric power system
新型电力调度自动化系统远程终端设计

The design and implementation of a new type Remote Terminal Unit(RTU) based on 32-bit ARM CPU LPC2214 in dispatching automation of electric power system were introduced. The shortcomings of the old RTU were analyzed and some improvements on software and hardware were put forward.Full advantages of integrated function blocks of LPC2214 were taken, and In-Application Programming(IAP) technology and Fourier algorithm were used to develop new type RTU. The new type RTU has simple peripheral circuits, high reliability, excellent expansibility and notably improved function. It is easy to be used and maintained, and easy to use the new type RTU to buildup large scale monitoring network.
