Recommendations for small renewable energy and hybrid systems for rural electrification - Part 7-1: Generators - Photovoltaic generators

Recommendations for small renewable energy and hybrid systems for rural electrification - Part 7-1: Generators - Photovoltaic generators

IEC/TS 62257-7-1:2010(E) specifies the general requirements for the design and the safety of generators used in decentralized rural electrification systems. Provides requirements for ELV and LV PV arrays. Particular attention must be paid to voltage level, as this is important for safety reasons and has an influence on protective measures and on the skill and ability level of operators. The main technical changes with regard to the previous edition are the following:
- this new version is focused on small PV generators up to 100 kWp;
- it provides case studies.

IEC 60904-7:2019(Main)
Photovoltaic devices - Part 7: Computation of the spectral mismatch correction for measurements of photovoltaic devices

IEC 60904-7:2019 is available as IEC 60904-7:2019 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
IEC 60904-7:2019 describes the procedure for correcting the spectral mismatch error introduced in the testing of a photovoltaic device, caused by the mismatch between the test spectrum and the reference spectrum (e.g. AM1.5 spectrum) and by the mismatch between the spectral responsivities (SR) of the reference device and of the device under test and therewith reduce the systematic uncertainty. This procedure is valid for single-junction devices but the principle may be extended to cover multi-junction devices. The purpose of this document is to give guidelines for the correction of the spectral mismatch error, should there be a spectral mismatch between the test spectrum and the reference spectrum as well as between the reference device SR and the device under test SR. The calculated spectral mismatch correction is only valid for the specific combination of test and reference devices measured with a particular test spectrum. This fourth edition cancels and replaces the third edition published in 2008. The main technical changes with respect to the previous edition are as follows:
- For better compatibility and less redundancy, the clause “Determination of test spectrum” refers to IEC 60904-9.
- The spectral mismatch factor is called SMM instead of MM to enable differentiation to the angular mismatch factor AMM and spectral angular mismatch factor SAMM.
- Formulae for the derivation and application of the spectral mismatch factor SMM are added.
- Links to new standards are given, e.g. concerning multi-junction devices.
- Corrected wording (responsivity instead of response and irradiance instead of intensity).

Electricity metering data exchange - The DLMS®/COSEM suite - Part 6-1: Object Identification System (OBIS)

IEC 62056-6-1:2023 is available as IEC 62056-6-1:2023 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 62056-6-1:2023 specifies the overall structure of the OBject Identification System (OBIS) and the mapping of all commonly used data items in metering equipment to their identification codes.OBIS provides a unique identifier for all data within the metering equipment, including not only measurement values, but also abstract values used for configuration or obtaining information about the behaviour of the metering equipment. The ID codes defined in this document are used for the identification of:
- logical names of the various instances of the ICs, or objects, as defined in IEC 62056‑6‑2:2023;
- data transmitted through communication lines;
- data displayed on the metering equipment, see Clause A.2 in Annex A.
This document applies to all types of metering equipment, such as fully integrated meters, modular meters, tariff attachments, data concentrators, etc.
To cover metering equipment measuring energy types other than electricity, combined metering equipment measuring more than one type of energy or metering equipment with several physical measurement channels, the concepts of medium and channels are introduced. This allows meter data originating from different sources to be identified. While this document fully defines the structure of the identification system for other media, the mapping of non-electrical energy related data items to ID codes is completed separately
This fourth edition cancels and replaces the third edition of IEC 62056-6-1, published in 2017. This edition constitutes a technical revision. The main technical changes with respect to the previous edition are listed in Annex B (informative).

IEC 60228:2023(Main)
Conductors of insulated cables

IEC 60228:2023 specifies the nominal cross-sectional areas, in the range 0,5 mm2 to 3 500 mm2, for conductors in electric power cables and cords of a wide range of types. Requirements for numbers and sizes of wires and resistance values are also included. These conductors include solid, stranded and Milliken, copper, aluminium and aluminium alloy conductors in cables for fixed installations and flexible copper conductors. This document does not apply to conductors for telecommunication purposes. The applicability of this document to a particular type of cable is as specified in the standard for the type of cable. Unless specified otherwise in a particular clause, IEC 60028 ED4 relates to the conductors in the finished cable and not to the conductor as made or supplied for inclusion into a cable. Conductors described in this document are specified in metric sizes. Informative annexes provide supplementary information covering temperature correction factors for resistance measurement (Annex B) and guidance on dimensional limits of circular conductors (Annex C). This document has the status of a horizontal publication in accordance with IEC Guide 108.
