Design of new digital HV protection hardware platform

On the basis of successful experience on conventional relay protection, a new hardware platform system of DSP & MPU is developed. This proposed system inherits the characteristics of high calculating ability, nice logical function, and other abundant source, while employs CMOS chips of large capability, consequently ensures the digital HV protection high-speed & real-time calculating, modular programming, fault processing report and sophisticated protection principle, as well as sufficient hardware redundance. This paper introduces the design thought, technology characteristic, working principle of such hardware platform, and then the implementation of the platform-based HV microprocessor-based line protection.
