| Abstract: | In power system, neutral low current grounded system's line-selection protection devices are deficient in the speed of response and the accuracy of selection. A high-speed data acquisition and processing system is made based on TI's DSP TMS320F206. In addition with CPLD as interface, a new line-selection protection device is constructed. Compared to the other protection devices, the rate of sampling and speed of selection are improved at least 10 times, and the precision of measure is increased by 60%. |
