Microgrids – Part 1: Guidelines for microgrid projects planning and specification

Published by: 2017-05-18 / 2017-05-18 / 33 pages
IEC TS 62898-1:2017(E) provides guidelines for microgrid projects planning and specification. Microgrids considered in this document are alternating current (AC) electrical systems with loads and distributed energy resources (DER) at low or medium voltage level. This document does not cover direct current (DC) microgrids.
Microgrids are classified into isolated microgrids and non-isolated microgrids. Isolated microgrids have no electrical connection to a wider electric power system. Non-isolated microgrids can act as controllable units to the electric power system and can operate in the following two modes:
– grid-connected mode;
– island mode.
This document will cover the following areas:
– microgrid application, resource analysis, generation forecast, and load forecast;
– DER planning and microgrid power system planning;
– high level technical requirements for DER in microgrids, for microgrid connection to the distribution system, and for control, protection and communication systems;
– evaluation of microgrid projects.

Electroacoustics – Simulators of human head and ear – Part 7: Head and torso simulator for the measurement of air-conduction hearing aids

Published by: 2017-04-12 / 2017-04-12 / 33 pages
IEC TS 60318-7:2017(E) describes a head and torso simulator, or manikin, intended for the measurement of air-conduction hearing aids in the frequency range from 100 Hz to 16 000 Hz.
The manikin described in this document is intended for airborne acoustic measurements only. It is not suitable for measurements which depend upon vibration transmission paths such as bone conduction, or for measurements requiring the simulation of bone or tissue. 
This document specifies the manikin in terms of both its geometrical dimensions and its acoustical properties. Only manikins compliant with both sets of specifications are in conformance with this document.
This edition includes the following significant technical changes with respect to the previous edition:
a)   the document is based on the designs of three different commonly used types of manikins;
b)   the cross sections of the head and torso and pinna simulators of the previous edition are replaced by maximum and minimum values of their geometric dimensions;
c)   the diffuse field frequency response of the manikin is added;
d)   the usable frequency range is extended to 100 Hz to 16 000 Hz;
e)   in addition to the cylindrical ear canal extension a tapered ear canal extension is added;
f)   design examples of one anatomically shaped manikin and of two different geometrically shaped manikins are given in the annexes;
g)   the relationship between tolerance interval, corresponding acceptance interval and the maximum permitted uncertainty of measurement are given in an annex;
h)   3D representations of three different types of pinna simulators are given in an annex.

Photovoltaic modules – Bypass diode electrostatic discharge susceptibility testing

Published by: 2017-04-10 / 2017-04-10 / 13 pages
IEC TS 62916:2017(E) describes a discrete component bypass diode electrostatic discharge (ESD) immunity test and data analysis method. The test method described subjects a bypass diode to a progressive ESD stress test and the analysis method provides a means for analyzing and extrapolating the resulting failures using the two-parameter Weibull distribution function. It is the object of this document to establish a common and reproducible test method for determining diode surge voltage tolerance consistent with an ESD event during the manufacturing, packaging, transportation or installation processes of PV modules.

IEC TS 62786:2017(E) provides principles and technical requirements for distributed energy resources (DERs) connected to the distribution network. It applies to the planning, design, operation and connection of DERs to distribution networks. It includes general requirements, connection scheme, choice of switchgear, normal operating range, immunity to disturbances, active power response to frequency deviation, reactive power response to voltage variations and voltage changes, EMC and power quality, interface protection, connection and start to generate electrical power, active power management, monitoring, control and communication, and conformance tests.
This document specifies interface requirements for connection of generating plants with the distribution network operating at a nominal frequency of 50 Hz or 60 Hz.
DERs include distributed generation and permanently connected electrical energy storage in the form of synchronous generators, asynchronous generators, converters, etc., connected to the medium voltage (MV) or low voltage (LV) distribution network.

Electroacoustics – Instruments for the measurement of sound intensity – Electromagnetic and electrostatic compatibility requirements and test procedures CONSOLIDATED EDITION

Published by: 2017-03-08 / 2017-03-08 / 26 pages
IEC TS 62370:2004+A1:2017 specifies requirements for instruments that measure sound intensity using pairs of pressure sensing microphones with respect to their immunity to power- and radio-frequency fields and to electrostatic discharge, and the permitted radio-frequency emissions, together with test procedures to verify conformance. Sound intensity measuring instruments are available in many different configurations and may be powered by batteries or from external power supply systems. The technical requirements in this Technical Specification apply to all configurations of instruments for the measurement of sound intensity. The electromagnetic and electrostatic compatibility requirements are equally applicable for sound intensity measuring instruments used in residential, commercial and light-industrial environments, or industrial sites. The requirements of this Technical Specification are additional to those contained in IEC 61043 and do not alter any of the specifications contained therein. The requirements do not apply retrospectively to sound intensity measuring instruments complying with IEC 61043 prior to the publication of this Technical Specification. This consolidated version consists of the first edition (2004) and its amendment 1 (2017). Therefore, no need to order amendment in addition to this publication.

Explosive atmospheres – Part 32-1: Electrostatic hazards, guidance CONSOLIDATED EDITION

Published by: 2017-03-16 / 2017-03-16 / 354 pages
IEC TS 60079-32-1:2013+A1:2017 gives guidance about the equipment, product and process properties necessary to avoid ignition and electrostatic shock hazards arising from static electricity as well as the operational requirements needed to ensure safe use of the equipment, product or process. It can be used in a risk assessment of electrostatic hazards or for the preparation of product family or dedicated product standards for electrical or non-electrical machines or equipment. The purpose of this document is to provide standard recommendations for the control of static electricity, such as earthing of conductors, reduction of charging and restriction of chargeable areas of insulators. In some cases static electricity plays an integral part of a process, e.g. electrostatic coating, but often it is an unwelcome side effect and it is with the latter that this guidance is concerned. If the standard recommendations given in this document are fulfilled it can be expected that the risk of hazardous electrostatic discharges in an explosive atmosphere is at an acceptably low level. This consolidated version consists of the first edition (2013) and its amendment 1 (2017). Therefore, no need to order amendment in addition to this publication.

Keywords: risk assessment of electrostatic hazards, static electricity
