Design

Distribution Automation and Feeder Automation Distribution Automation (DA) as a concept emerged in the 1970s to promote the application of computer and communications technologies for improving of distribution system operating performance. It is in general used as an umbrella term to describe the deployment of automation technologies for protection, control, monitoring, and operation of distribution systems.

The current document mainly describes the following functions of Distribution/Feeder Automation Systems:

Use of IEC 61850 for Electrical Energy Storage Systems is progressing these days. The latest draft describes the basic functions of Electric Energy Storage System (EESS) and the information model of the interface to integrate EESS in intelligent grids and establish the necessary communication with standardised data objects. The next official draft is expected to be published soon.

IEC 61869-9:2016 is a product family standard applicable to instrument transformers with digital output. The product standard is composed of IEC 61869-1 and IEC 61869-6, in addition to this standard and the relevant product specific standards in the IEC 61869 series (Part 7, Part 8, Part 12, Part 13, Part 14, and Part 15). This standard defines requirements for digital communications of instrument transformer measurements.

IEC 61131-3:2013 specifies the syntax and semantics of a unified suite of programming languages for programmable controllers (PCs). This suite consists of two textual languages, Instruction List (IL) and Structured Text (ST), and two graphical languages, Ladder Diagram (LD) and Function Block Diagram (FBD). This third edition cancels and replaces the second edition, published in 2003 and constitutes a technical revision. It includes the following significant technical changes: It is a compatible extension of the second edition.

Defines a language for the programming of Fuzzy Control applications used by programmable controllers.

ISO 6469-1:2009 specifies requirements for the on-board rechargeable energy storage systems (RESS) of electrically propelled road vehicles, including battery-electric vehicles (BEVs), fuel-cell vehicles (FCVs) and hybrid electric vehicles (HEVs), for the protection of persons inside and outside the vehicle and the vehicle environment. Flywheels are not included in the scope of ISO 6469-1:2009.
ISO 6469-1:2009 does not apply to RESS in motorcycles and vehicles not primarily intended as road vehicles, such as material handling trucks or fork-lift trucks.

ISO 6469-2:2018 specifies requirements for operational safety specific to electrically propelled road vehicles, for the protection of persons inside and outside the vehicle.
NOTE 1 Relevant requirements for motorcycles and mopeds are described in ISO 13063.
ISO 6469-2:2018 does not provide comprehensive safety information for manufacturing, maintenance and repair personnel.
ISO 6469-2:2018 does not consider specific aspects of driving automation features.
NOTE 2 For definition of the term "driving automation features", see SAE J3016.

Provides information on the physical and chemical properties of hydrogen and proper handling and use. It is intended to provide background information for personnel involved in the manufacture, distribution, and use of hydrogen. Additional technical information can be obtained from hydrogen gas manufacturers.

This publication presents design guidelines for hydrogen vent systems used in gaseous and liquid hydrogen systems at user sites and provides recommendations for safe operation of these vents. It begins at the discharge port of safety devices and other components that control the release of hydrogen and ends at the point where hydrogen concentration in the atmosphere is below the lower flammable limits. It also provides information on the production, transportation, handling, and storage of compressed hydrogen, cryogenic liquid hydrogen, and related products.
