一种基于图形化编程技术的馈线保护装置的研制

Development of a protective relay for feeders based on graph-oriented programming technique

结合我国微机保护现状,提出了一种新型的馈线保护方案及主要的实现方法,它成功地将图形化编程技术应用于馈线保护,并采用了32位低功耗DSP技术,实现了保护、测控功能并行实时处理,改善了技术指标,提高了系统可靠性,具有体积小巧,成本低廉等特点。

This paper proposes and creats a new kind of protective relay for feeders based on the current development situation of the protective relay in our country. The main feature of the proposed protective relay is that the graphoriented programming technique is successfully used. The protective relay is realized with 32 bit lower power loss DSPs to perform the functions of relaying, measuring and controlling in the real time. As a result, both the technique characteristics and the reliability of the developed relay are greatly improved. Additional advantages of the developed relay are its small size and low cost.
