| Abstract: | The research and development of EHV line protective device based upon 32-bit DSP and WXH-801/802 digital microprocessor_based line protection system are introduced in this paper. Its CPU adopts many advanced technologies such as digital signal processor, large capacity FLASH and RAM, programmable CPLD, 16-bit A/D etc. Man Machine Interface (MMI) exploits 80x86. The protection principles take advantage of adaptive frequency track and adaptive synthesis criterions. |
