| 摘 要： | 基于双母线四分段主接线方式,提出了一种四台主变互为备自投功能的逻辑控制策略,给出具体设计方案,在完成基本备自投功能的基础上增加了备自投过程中的同期判断功能和备自投成功后的过载切负荷功能,并在备自投过程中考虑了可备自投开关优先级问题。该备自投功能已在SCS-500备自投装置上实现并成功应用。

| Abstract: | Based on dual-busbar four-section main wiring method, this paper raised a logical control strategy of four main transformers in mutual auto-switch-on function, giving the actual design plan. On the basis of ifnishing the basic auto-switch-on function, the synchronous judgement function in auto-switch-on process and over-load switch-off function after success of auto-switch-on were added, and in auto-switch-on process possible switch-on switch priority was taken into consideration. The SCS-500 auto-switch-on device has realized the auto-switch-on function. |
