摘　　要：提出了一种新型的适用于配电网的微机保护,硬件设计采用"DSP+MCU"的双CPU结构,充分发挥了DSP强大的数据处理能力和MCU的事件管理能力,可以满足配电网对保护装置的要求。软件设计将μClinux嵌入式实时操作系统引入微机保护平台。该保护装置设计合理,能够满足相关保护的技术指标要求,具有高精度和高速通信的特点,可满足配网自动化的需求。A new microcomputer relay protection device was proposed for power distribution system. In the hardware design, ＂DSP ＋ MCU＂ dual-CPU architecture was used, which gives full play to the poweiful DSP data processing capability and MCU event management capability, thus satisfying the distribution protection require- ments. In the software design, p, Clinux embedded real-time operating system was introduced into microcomputer re- lay protection. The research and experimental results indicate that the designed structure is reasonable, and has high precision and high-speed communications features, which can meet the needs of power distribution system automation.
