Full Description

Scope

This part of IEC 61000 provides guidance on principles which can be used as the basis fordetermining the requirements for the connection of fluctuating installations to MV, HV andEHV public power systems (LV installations are covered in other IEC documents). For thepurposes of this report, a fluctuating installation means an installation (which may be a load ora generator) that produces voltage flicker and / or rapid voltage changes. The primaryobjective is to provide guidance to system operators or owners on engineering practiceswhich will facilitate the provision of adequate service quality for all connected customers. Inaddressing installations, this document is not intended to replace equipment standards foremission limits.This report addresses the allocation of the capacity of the system to absorb disturbances. Itdoes not address how to mitigate disturbances, nor does it address how the capacity of thesystem can be increased.Since the guidelines outlined in this report are necessarily based on certain simplifyingassumptions, there is no guarantee that this approach will always provide the optimumsolution for all flicker situations. The recommended approach should be used with flexibilityand engineering judgment as far as engineering is concerned, when applying the givenassessment procedures in full or in part.The system operator or owner is responsible for specifying requirements for the connection offluctuating installations to the system. The fluctuating installation is to be understood as thecustomer's complete installation (i.e. including fluctuating and non fluctuating parts).Problems related to voltage fluctuations fall into two basic categories:* Flicker effect from light sources as a result of voltage fluctuations;* Rapid voltage changes even within the normal operational voltage tolerances areconsidered as a disturbing phenomenon.The report gives guidance for the coordination of the flicker emissions between differentvoltage levels in order to meet the compatibility levels at the point of utilisation. This reportprimarily focuses on controlling or limiting flicker, but a clause is included to address thelimitation of rapid voltage changes.NOTE The boundaries between the various voltage levels may be different for different countries (seeIEV 601-01-28) [16]. This report uses the following terms for system voltage: low voltage (LV) refers to Un 1 kV; medium voltage (MV) refers to 1 kV < Un 35 kV; high voltage (HV) refers to 35 kV < Un 230 kV; extra high voltage (EHV) refers to 230 kV < Un.In the context of this report, the function of the system is more important than its nominal voltage. For example, aHV system used for distribution may be given a "planning level" which is situated between those of MV and HVsystems.

Abstract

Adoption Standard - Active.IEC/TR 61000-3-7:2008 is adopted by this guide. IEC 61000-3-7:2008 provides guidance on the principles that can be used as the basis for determining the requirements for the connection of fluctuating installations to MV, HV, and EHV power systems (LV installations are covered in other IEC documents). The primary objective of this guide is to provide guidance to system operators or owners on engineering practices that will facilitate adequate service quality for all connected customers.This guide provides a methodology to allocate the capacity of the system to absorb voltage fluctuations (i.e., flicker). However, it does not address how to mitigate voltage fluctuations, nor does it address how to increase the capacity of the system to absorb such disturbances.Since the procedures outlined in this guide are necessarily based on certain simplifying assumptions, the approach will not always provide an optimum solution. The recommended approach should be used with flexibility and engineering judgment, when applying the given assessment procedures in full or in part.
