Microgrids - Part 3-4: Technical requirements - Microgrid monitoring and control systems
IEC TS 62898-3-4:2023 provides technical requirements for the monitoring and control of microgrids. This document applies to non-isolated or isolated microgrids integrated with distributed energy resources. This document describes the specific recommendations for low-voltage (LV) and medium-voltage (MV) microgrids.
This document focuses on standardization of the architecture, functions, and…
Light and lighting — Building information modelling properties for lighting — Lighting systems
This technical specification identifies and clarifies lighting properties for digital building design and maintenance.
This document provides all the needed properties to design and to describe lighting systems. These properties are intended to be used for mapping between data providers and requesters. The mapping of the identifiers enables the exchange of luminaire and sensing device data within…
Corrigendum 1 - High-voltage switchgear and controlgear - Part 202: AC prefabricated substations for...
IEC 62271-202:2022 specifies the service conditions, rated characteristics, general structural requirements and test methods of enclosed high-voltage prefabricated substations. These prefabricated substations are cable-connected to AC high-voltage networks with an operating voltage up to and including 52 kV and power frequencies up to and including 60 Hz. They can be manually operated from inside…
Geographic information — Metadata — Part 3: XML schema implementation for fundamental concepts
This document defines an integrated XML implementation of ISO 19115-1 and ISO 19115-2 by defining the following artefacts:
—    a set of XML schema required to validate metadata instance documents conforming to conceptual model elements defined in ISO 19115-1 and ISO 19115-2; and
—    a set of ISO/IEC 19757-3 (Schematron) rules that implement validation constraints in the ISO 19115-1 and ISO…
Communication networks and systems for power utility automation - Part 90-7: Object models for power...
IEC TR 61850-90-7:2023 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition.
IEC TR 61850-90-7:2023, which is a Technical Report, describes functions for power converter-based distributed…
Communication networks and systems for power utility automation - Part 90-7: Object models for power...
IEC TR 61850-90-7:2023, which is a Technical Report, describes functions for power converter-based distributed energy resources (DER) systems, focused on DC-to-AC and AC-to-AC conversions and including photovoltaic systems (PV), battery storage systems, electric vehicle (EV) charging systems, and any other DER systems with a controllable power converter. The functions defined in this document…
Cleanrooms and associated controlled environments — Part 21: Airborne particle sampling techniques
This document discusses the physical limitations of probe and particle counter placement, and any tubing that connects the two, particularly in providing representative samples where particles 5 micrometres and greater are of interest.
The document further identifies the key factors of sampling performance when classifying and monitoring, and good practice to determine and maintain an acceptable…
