Microgrids - Part 3-1: Technical requirements - Protection and dynamic control
IEC TS 62898-3-1:2020(E) provides guidelines for the specification of fault protection and dynamic control in microgrids. Protection and dynamic control in a microgrid are intended to ensure safe and stable operation of the microgrid under fault and disturbance conditions.
This document applies to AC microgrids comprising single or three-phase networks or both. It includes both isolated…
Road vehicles — Media Oriented Systems Transport (MOST) — Part 6: Data link layer
This document specifies technical requirements related to the MOST data link layer functionality.
A MOST network is comprised of two or more nodes connected through a physical layer. The data link layer functionality is provided by each node. On each network, all nodes are synchronised and one node provides the system clock. This node is the TimingMaster, while all other nodes are TimingSlaves.…
