Design of Power Distribution Line Microcomputer Protection Device

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.
