    Why do we need precision timing in DSS? Digital Substations (DSS) rely on devices distributed across different locations and must have the same time. This time synchronization is essential to calculate the accurate value of currents and support differential protection schemes and other critical functions that ensure the grid is highly reliable and expensive equipment…

    Two topics keep coming up in the CIGRE 2024 B5 discussions: network redundancy and time synchronization. Indeed, these are two fundamental design characteristics that ensure the digital substation (DSS) meets the grid’s high expectations for reliability. This is a summary of my findings related to PRP v. HSR. In a digital substation, trip signals are…

    Continuing to share my learning from attending CIGRE 2024 B5 discussions and reading the latest papers on digital substation… A Process Interface Unit (PIU) and a Merging Unit (MU) are components used in digital substations based on the IEC 61850 standard. They have different roles and levels of complexity, primarily focusing on interfacing with the…
