摘要
介绍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,以距离保护和零序保护为主保护,在软件方面应用多种智能化技术,提高了保护性能,详细介绍了保护的主要技术特点。动模测试结果表明,该装置整体性能优良,能够满足110 kV线路对距离保护的要求。
A new high-voltage transmission-line microprocessor-based protection equipment is introduced in this article.The designation of this equipment is based on digital signal processor（DSP）.A multi-CPU structure is adapted,and distance protection and zero-sequence（direction） protection are used as the main protection.At the same time,a variety of intelligent technology is applied in terms of software application,which greatly increases its performance of protection.Besides,the principal technical characteristics are detailed.Large number of trials and dynamic-simulation-test results show that the overall performance of this equipment is as fine as to meet the distance protection requirements of 110 kV lines.
