| 摘 要： | 介绍了在柘林水电厂开关站现地控制单元（LCU）原有控制输出回路中增加DOP-1型输出保护装置，避免由于开出模件故障导致相关设备误动作而造成的损失。DOP-1型输出保护装置在同一时间只允许1个开出点动作，当有多个开出点同时动作时DOP-1装置会自动闭锁开出动作。文中详细介绍了改造前、后开出原理的对比，以及改造完成后的开出保护功能及实施效果。

| Abstract: | DOP-1 output-protection is applied to the output control loop of the switch station LCU at the Zhelin Hydropower Plant to avoid maloperation of related equipment induced by the fault of output modules. DOP-1 output-protection allows only one output point to operate at one time. If two or more output points operate at one time, DOP-1 output-protection can hold up the output operation automatically. The output principle before and after the reform is described in detail, and the effect of the output-protection is introduced. |
