Abstract

See full text

Disclosed herein is a system for time aligning electric power system measurements at an intelligent electronic device (IED) using samples and sample time offset from merging units. The merging units do not require access to a common time signal. The IED does not require storage of a communication latency with the merging units. The sample time offset corresponds to a latency between obtaining the sample and receipt of the sample at the IED. The IED aligns samples from various merging units using sample time offset values communicated from the merging units to the IED. The IED performs monitoring and protection functions using the time aligned samples.
