摘要
通过对微机保护改造工作现状的分析,指出了微机保护改造工作存在的问题,提出了微机保护统一保护屏配置、统一尺寸、统一端子、统一信号的新"四统一"设计原则的建议,并对新"四统一"原则进行了详细的阐述。最后以典型的改造项目为例,分析对比得出采用新"四统一"方案可以显著地降低改造成本,大大地减少工作量。
Through the analysis of the current status, this paper indicates the problems existing in the microprocessor-based protection equipments transformation projects, and makes a specific statement of new ＂four-unification＂ principle including unification of protection-configuration,unit-size,terminal-arrangment and signal-output. Taking the typical transformation projects as examples, this paper concludes that the new ＂four-unification＂ method could lower the cost the transformation project significantly and decrease the project workload as well.
