摘　　要：介绍了一种基于数字信号处理器 (DSP)的新型高压输电线路微机保护装置。它采用多CPU结构 ,以距离保护和零序 (方向 )保护为主体 ,并在硬、软件方面应用了多种智能化技术措施 ,从而大大提高了保护性能。该装置结构紧凑 ,可靠性高 ,人机界面友好 ,适用于各种超高压输电线路保护。目前已完成了An advanced protection based on digital signal processor (DSP) for HV Power transmission line is introduced. It has two CPUs and the distance relay and zero sequence directional overcurrent relay are its main protections.The applied new intelligent technology in both HW and SW improver its performance greatly. This protection device has compact structure, high reliability and friendly man machine interface.Its prototype for 110 kV has completed.
