IEEE 1453 2015 Edition, September 3, 2015 Recommended Practice for the Analysis of Fluctuating Installations on Power Systems
More info
Description / Abstract:
This recommended practice provides background on light flicker
caused by fluctuations in power demands of variable loads. A
flicker measurement method is presented using a meter that is
completely described in IEC 61000-4-15. The short-term
(Pst) and long-term (Plt) flicker indices used
for the analysis of flicker data are defined. Flicker limits for
various voltage levels are presented. An assessment procedure for
evaluating flicker compliance against emission limits is described.
Methodologies to analyze background flicker to identify the flicker
contribution of single loads are also presented.
The document provides ways to estimate flicker levels at the Point of Common Coupling (PCC) depending on the type of the load. This document includes example terms and language that can be the basis for defining relative responsibilities and assessment methods for customer installations that may cause flicker.
Purpose
The purpose of this document is to provide guidance to system operators, owners, and engineers who are responsible for providing electrical service to installations that cause voltage fluctuations. It provides guidance on the principles and methodology that can be used to determine requirements for connecting fluctuating loads to both radial and network systems. Methods for determining appropriate flicker planning levels and emission limits for fluctuating loads as well as those that create rapid voltage changes are provided.
