图形化编程与继电保护装置开发

Discussion of graphical programming and protective relay development

数字式保护装置的开发手段对保护装置的可靠性具有决定性影响。介绍了数字式保护装置开发手段的现状,指出了基于人工录入计算机语言的常规开发手段的缺点。通过分析提出了基于图形化语言进行保护装置开发的思想,对其优越性进行了阐述,实现所见即所得的开发,从开发手段上保证了保护装置的可靠性。通过一个应用实例,说明了运用图形化语言编程技术进行继电保护装置开发的可行性和优势。

The development methods have a critical influence on the reliability of digital protective relay.The status quo of means in developing digital protective relay is introduced and the shortco - mings of conventional computer language typing are indicated.A methodology of developing protec-tive relay based on graphical programming is presented to realize the development mode of'What you see what you get'.Therefore,the reliability of digital protective relay can be substantially guaranteed.An application example is used to illustrate the feasibility and superiority of the proposed graphical programming method.
