摘要
提出了一种适用于复杂供用电系统谐波检测的同步基准信号自适应滤波技术 ,该方法无需外部硬件锁相环 ,特别适合于基波频率变化且难以获得同步基准信号的场合 ,并在交流励磁发电系统谐波检测中得到了验证。
A Kind of adaptive filtering technique of the synchronizing datum signal was proposed in the paper, which is suitable for the harmonic detection of the complicated power supply system. The approach is unnecessary to have the phase locking loop, which especially fit the situation where the fundamental frequency is variable and the synchronizing datum signal is difficult to acquire. This method has been verified in the harmonic detection of an a.c excited generation system.
