摘要
提出了一种新的编程方法来实现微机保护——可视化保护。可视化保护的思想是根据相应的保护定制对应的保护逻辑图,然后在保护平台上搭建图形程序,运行得到可执行程序,再下装到硬件平台中。介绍了可视化平台的功能与特点——高效性、可靠性、灵活性和开放性。论述了可视化平台微机保护系统的结构、功能和特点,以及保护元件库的构成。通过实现方向低压闭锁过流保护的应用实例说明了可视化编程方法在微机保护中应用的可行性和优点,并对可视化编程与常规编程两种不同方法进行了比较。得出的结论是可视化编程在微机保护中的应用具有非常重要的意义,使微机保护的实现变得更加简单、灵活和可靠。
This paper presents a new programming approach to microcomputer-based protection -- visual protection. The idea of visual protection is getting protection logic figure, building graph program, running and loading down to hardware platform. A new visual platform function and characteristic-high efficienty, reliability, flexibility and openness is introduced .In addition, a visible platform is discussed for microcomputer-based protection system structure, functions and features, and the composition of the protection components.An application example of directional overcurrent protection with undervoltage-locked is used to illustrate the feasibility and superiority of the visual programming method in microcomputer-based protection, and the visual programming method is compared with the general programming method. The conclusion is that visual programming in the protection is of very important significance,and microcomputer-based protection of the more simple, flexible and reliable.
