摘　　要：TMS320LF2407是TI公司最新推出的TMS320C2000系列DSP产品,它比起一般的微机型的继电保护单元中大量使用的MCU有着明显的优势,表现为低成本、低功耗、高性能的处理能力。这对提高电网数据采集和处理能力,解决分立的保护单元之间的通讯问题都带来了很大的帮助,尤其是在继电保护这类实时性要求高的场合中得到了广泛的应用。本文讨论的是以LF2407型DSP为核心的模块在高压断路器智能测控单元中的应用,并从硬件电路的结构及软件设计的流程两方面分别加以阐述。TMS320LF2407 is the newest product introduced by Tl company of it's TMS320C2000 series. It has quite a few advantages when compared to MCUs which is widely used in the relay protection units with simple microprocessors.which are low cost,low power consumption and high performance.It is helpful to reinforce the capacity of data sampling and proceeding in power network. and is benefit to solve the communication problem among distribated protection units. especially to relay pro- tection which requires high real time performance.This thesis will mainly discuss the application of LF2407 DSP in intelligent ineasure and control unit in high voltage circuit breaker.and it will expatiate the application in two aspects: the hardware archi- teture and the software flow.
