The application of IEC61850 and non-conventional instrument transformers (NCIT) brings a new era in the development of substation. The protection intelligent electronic device (IED) in digital substation receives sampled data from different digital data sources (DDS) with digital interface based on IEC 61850-9-2 process bus. The mismatch in sampling rate between protection IED algorithms and different...
The application of IEC61850 and non-conventional instrument transformers (NCIT) brings a new era in the development of fully digital protection system in which the protection IED receives sampled data from different digital data sources (DDS). The mismatch in sampling rate between the protection IED and the DDS requires sampling rate synchronization (SRS) to make sure the protection and other algorithms...
