摘要
介绍了利用同步锁相技术控制电网谐波分析仪中信号的采集，阐述了该仪器中锁相环控制电路的结构和工作原理。实践表明，采用此项技术可以有效地提高谐波仪的测量分析精度。
The application of synchronous phase locking technology to contrOl signalsampling in the power network harmonic analyser is introduced and the structure and workingprinciple of Phase locking controlling circuit are described. It has been proved in practice that themeasurement precision of the insttument can be improved by using this technology.
