摘　　要：现有光纤通道中继电保护测试信号增强模型存在目标设定单一、执行流程固定、信号增强效率低等问题,导致信号波动比下降,因此提出电力光纤通道中继电保护测试信号增强方法。该方法根据当前的信号增强需求,采集信号并设置信号增强原则,利用自适应方式,提高信号的实际增强效率,并构建自适应光纤通道继电保护测试信号增强模型。此外,该方法采用均衡补偿处理的方式实现信号增强。测试结果表明,所提方法的信号波动比在3.0上下浮动,证明了该方法的优越性和有效性。The current relay protection test signal enhancement model in fiber optic channels is mostly set as target enhancement,with a relatively fixed execution process and low signal enhancement efficiency,resulting in a decrease in the final signal fluctuation ratio.Therefore,a relay protection test signal enhancement method in power fiber optic channels is proposed.Based on the current signal enhancement requirements,signal acquisition and signal enhancement principles should be set first,and an adaptive approach should be adopted to improve the actual enhancement efficiency of the signal.An adaptive fiber channel relay protection test signal enhancement model should be constructed,and balanced compensation processing should be used to achieve signal enhancement.The test results show that the signal fluctuation ratio of the proposed method fluctuates around 3.0,proving its superiority and effectiveness.
