HW design of an intelligent protective unit

Based on the analysis of the actuality and requirements of protective unit's hardware, a HW design of intelligent protective unit is brought forward. It takes TMS320c2Cxx DSP as its core and some peripheral circuits. DSP's high speed operation capability and abundant peripheral circuits supports the HW basis for complicated protection algorithms. It integrates many functions of measuring, protection and communication together and has many advantages of higher performance and lower price.
