一例变电站计算机监控系统控制回路的改进

分析了一例变电站计算机监控系统断路器的控制回路的原理,阐述了在就地控制、远方遥控两种方式实现断路器跳闸、合闸的过程,指出了就地同期合闸时微机五防电脑钥匙不能正常跳步的原因,提出具体的解决方案。在不增加任何设备、不改变原来的操作方式的条件下,合理利用原有装置内部元件,优化控制回路,远方操作和就地操作、同期和闭锁同期等均无异常,解决了就地同期合闸时电脑钥匙不跳步的问题。

Improvement of Breaker Control Circuit of Substation Automation System

Analyzed a principle of breaker control circuit of substation automation system, elaborated to carry out breaker to trip and close process on local control and remote control, point out the reason that computerized five-prevention key can't normally jump at local synchronization closing, points out the solved methods. Under the condition that don't increase any equipments and don't change an original operation method, reasonable make use of original equip inside of component, optimize control circuit, local...
