| 摘要: |
| 提出一种新型的微机励磁调节器双通道热备方法,为每个励磁系统配置2个微机励磁调节器,一个为主机,另一个为热备机,利用2个励磁调节器的主控芯片直接检测主机与热备机的工作状态、逻辑仲裁及切换控制,节省了额外的逻辑仲裁电路.设计了一种更加可靠的晶闸管触发脉冲控制和闭锁方式,并通过硬件逻辑电路实现.给出了双通道励磁调节器组成图、双通道之间逻辑信号接口电路、触发脉冲二次控制电路.该方法在试验及中小型发电站的实际应用中效果良好. |

| Abstract: |
| A double-channel hot standby method is proposed,equiping two excitation regulators for each ex- citation system,on-line and hot-standby.The master chip of the regulator detects the working states of both regulators,executes logic arbitration and changeover control,without extra logic arbitration circuit.A more reliable control and locking mode is designed for the triggering pulse of thyristor,which is realized by hardware logic circuit.The structure of excitation system with two regulators is presented,toge... |
