提出了一种适合智能变电站特点的手合检同期方法。同期采样基于IEC 61850-9-2采样值传输标准,充分考虑采样过程的丢点、不同步等异常处理。进行频率跟踪重采样,保证同期量测精度。按检同期结果建立通信模型,通过通用面向对象的变电站事件（GOOSE）输出控制智能终端,为手合操作提供闭锁。所提出方法已在智能变电站测控装置中实现并在工程中得到应用。

A synchronization method of breaker manual closing,which is suitable to smart substation characteristics is presented.The synchronization sampling signal is based on IEC 61850-9-2 acquired value transfer standard which adequately considers the abnormal situations such as losing sample value points and sample value sequence asynchronous between channels,etc.The sample value is re-sampled and re-sampling frequency is tracking with real signal so that ensures the accuracy of synchronization measurement.The results of synchronization judgment creates communication model and through general object-oriented substation event（GOOSE） output control smart execution terminal provides lock for breaker manual closing.The proposed method is realized in measuring and control device of smart substation and applied in engineering projects.
