摘要
数字式保护和安全自动装置正在向软硬件平台化、功能开发组态化的方向发展。本文以发电厂厂用电快切装置为例,介绍了基于平台化设计思想的数字式保护和自动化装置的组态化开发过程,说明了基于IEC 61131-3标准、以保护控制功能块为核心的图形化软件开发方法。
The hardware and software platform technique and graphic oriented programming technique are popular to power control device and digital relay. A new developing scheme is introduced based on platform technique. A new developing mode based on IEC61131-3 is suggested. The implemented process of the graphical oriented programming scheme and its effect on improving the reliability and maintainability of the software are illuminated. Test result shows that the graphical programming scheme based on IEC61131-3 is efficient.
