| Abstract: |
| 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. |
