摘要
介绍了一种基于DSP的新型超高压输电线路微机保护方案。它采用双主双后的配置 ,重合闸相对独立。在保护原理方面采用了补偿电压突变量方向元件和双原理综合接地距离继电器等新方案 ,并在软件流程方面采取了模块化设计 ,从而大大提高了保护性能。该方案结构紧凑 ,可靠性高 ,人机界面友好 ,通讯功能强大 。
A novel UHV transmission line protection system based on digital signal processor (DSP) is introduced. It has two DSPs each of which includes primary protection ,backup protection and independent switch recloser. In the principles of protection, directional protective relay based on fault component of compensation voltage and double principles ground distance relay are applied. In addition, module design is applied in software programming. All these improved capability of protection. The protection device has compact structure, high reliability,friendly man machine interface, powerful communicating function and can be used in all kinds of UHV transmission line protection system.
