摘要

针对数字化变电站二次智能电子设备（IED）采样数据源的多样性导致采样数据不同步及采样频率不一致的问题，从智能设备数据处理角度，对二次设备采样时序、数据同步插值等因素进行分析，提出解决二次IED数据采样不同步及采样频率不一致的方法，该方法增强了不同采样模式下智能设备整体采样数据的有效性。

Abstract

In connection with the diversity of the IED input analogs in digital substation resulting in synchronization with different sampled values and different sample frequencies， an analysis is made of the time sequence of the IED sample in a digital substation and the factors for consideration in the synchronization and interpolation algorithm of sampled values from the perspective of IED data processing. Then the design of the synchronization and interpolation algorithm of sampled values is described. The method proposed has improved the effectiveness of the whole sampled values in different sampling modes.
