LVDC systems - Assessment of standard voltages and power quality requirements

LVDC systems - Assessment of standard voltages and power quality requirements

IEC TR 63282:2020(E) collects information and reports experience in order to make recommendations for the standardization of voltage levels and related aspects (power quality, EMC, measurement …) for LVDC systems (systems with voltage level lower than 1 500 V d.c.).
Rationale for the proposed voltage values are given. Variation of parameters for the voltage (power quality) and recommendation for their boundaries are defined. Nevertheless, some of the technical items are not exhaustively explained in this document and some gaps are identified for future work.
Attention is paid to the definition of DC voltage.
Systems in which a unipolar voltage is interrupted periodically for certain purposes, e.g. pulse voltage, are not considered.
Traction systems are excluded from this document

IEC TS 63191:2023(Main)
Demand-side power quality management

IEC TS 63191:2023 specifies recommendations about power quality measurement and assessment within installations.
This document outlines the various phases needed for the establishment of a demand-side power quality measurement plan for buildings and industry installations.
Such a power quality measurement plan will enable the optimization of the energy availability and efficiency, improve the assets lifetime and facilitate the resolutions of power quality problems. A power quality measurement plan encompasses the following phases:
• definition of the context, objectives and constraints;
• assessment of the initial power quality situation;
• definition of an action plan for the improvement of the power quality situation;
• implementation of the power quality measuring system;
• exploitation of the measurement system for the improvement of the power quality situation;
• maintenance of the measurement system.
This document will also help facility managers tailor their measurement plan to the specific needs of the electrical system under their control. It addresses all the disturbances present in such networks, but does not cover the disturbances present in public electrical distribution networks (supply side) as they are governed by specific documents such as EN 50160 and IEC TS 62749.
IEC TS 63191:2023 cancels and replaces IEC TR 63191, published in 2018. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) a new informative Annex A describing a tool to report the ability to assess the power quality of an electrical installation.

This document includes guidelines for architects, interior designers and facility managers.
Hazards, nuisances and other problems associated with electrostatic phenomena and the principles of their control are outlined. This document includes requirements and recommendations for materials, and products used to control static electricity.
The handling of electrostatic sensitive components is described in IEC 61340-5-1 and the avoidance of hazards due to static electricity in explosive atmospheres is presented in IEC TS 60079-32-1. The requirements for electrostatic control in healthcare facilities are specified in IEC 61340-6-1. The guidance in this document is not intended to replace or supersede the requirements of the aforementioned standards and technical specification, but can be used in association with them to establish appropriate electrostatic control measures.
These guidelines do not replace or supersede any requirements for personnel safety specified in other standards or codes of practice.

IEC 61936-2:2023(Main)
Power installations exceeding 1 kV AC and 1,5 kV DC - Part 2: DC

IEC 61936-2:2023 provides, in a convenient form, requirements for the design and the erection of DC installations in systems with nominal voltages above 1,5 kV DC, so as to provide safety and proper functioning for the use intended.
For the purpose of interpreting this document, a DC installation is considered to be one of the following:
a) A converter station or DC switching station;
b) one (or more) DC generating or storage unit(s), such as solar farms or battery storage units, located on a single site, the DC installation includes DC equipment and cables with all associated power electronics, controlgear, switchgear and all electrical auxiliary systems. Connections between DC generating or storage units located on different sites are excluded;
c) DC installation erected on offshore facilities for the purpose of generation, transmission, distribution and/or storage of electricity; or
d) DC transition station (between overhead lines and underground cable or between different sections of underground cables).
This International Standard does not apply to the design and erection of any of the following:
- overhead and underground lines between separate installations;
- electric railways;
- mining equipment and installations;
i- installations on ships according to IEC 60092 series and offshore units according to IEC 61892 series, which are used in the offshore petroleum industry for drilling, processing and storage purposes;
- electrostatic equipment (e.g. electrostatic precipitators, spray-painting units);
- test sites;
- medical equipment, e.g. medical X-ray equipment;
- valve hall or converter hall.
This document does not apply to the requirements for carrying out live working on electrical installations.
This document does not apply to the design of factory-built, type-tested thyristor valves, VSC valves and switchgear for which separate IEC standards exist.
This first edition cancels and replaces the IEC TS 61936-2 published in 2015. This edition constitutes a technical revision.
See the foreword of this edition for the list of significant technical changes with respect to the previous edition.
