摘　　要：阐述了在500kV大黔双回线、黔烽Ⅰ回线停电加固期间500kV黔烽Ⅱ回线路光差保护没有光纤通道，临时将黔烽Ⅱ回线路光差保护改造成载波保护运行，成功解决了在500kV大黔双回线、黔烽Ⅰ回线停电加固期间，黔烽Ⅱ回线路只单主保护运行。This paper expounded the 500 kV Qianfeng Ⅱ back line had not fiber channel for optical differential protection during the 500 kV Daqian double line and Qianfeng Ⅰ back line at the time what power failure and reinforcement. Temporarily transformed Qianfeng Ⅱ back line optical differential protection into carrier protection operation, successfully solved the problem of Qianfeng Ⅱ back line only single primary protection operation during the 500 kV Daqian double line and Qianfeng Ⅰ back line power failure and reinforcement.
