Benchmarking of Power Quality Performance in Transmission Systems - CIGRE WG C4.27 perspective

Abstract

Abstract-This paper describes the activities of CIGRE WG C4.27 "Benchmarking of Power Quality Performance in Transmission Systems". The WG was established in December 2012 in recognition of demand for coherent set of guidelines for benchmarking power quality performance in existing and future transmission networks. During the work the members of the WG have compiled extensive material related to the state of the art of benchmarking power quality performance in transmission systems. This paper summarizes current understanding of benchmarking power quality performance issues and identifies directions in which the WG will continue to work in order to provide resolutions to outstanding questions. Index Terms-Power quality, power quality measurements, power quality benchmarking, power quality parameters.

A general process recommended by CIGRE WG C4.27 for benchmarking power quality performance in transmission systems

“…During the work, a significant amount of information from the literature and from the experience of the WG members was collected and analysed. First results of the understandings of PQ performance were presented in [2]. Based on the further assessment and dialogues between different contributors, the WG proposed guidelines for PQ benchmarking by recommending a suitable set of indices that can be used for this purpose and by advising on the general process and methodology for gathering and using the data required for benchmarking.…”
