This part of IEC 61400 provides guidance on principles which can be used as the basis for determining the application, structure and recommendations for the WT harmonic model. For the purpose of this Technical Report, a harmonic model means a model that represents harmonic emissions of different WT types interacting with the connected network. This document is focused on providing technical guidance concerning the WT harmonic model. It describes the harmonic model in detail, covering such aspects as application, structure, as well as validation. By introducing a common understanding of the WT representation from a harmonic performance perspective, this document aims to bring the overall concept of the harmonic model closer to the industry (e.g. suppliers, developers, system operators, academia, etc.). A standardized approach of WT harmonic model representation is presented in this document. The harmonic model will find a broad application in many areas of electrical engineering related to design, analysis, and optimisation of electrical infrastructure of onshore as well as offshore WPPs.Cross References:IEC 60050-415:1999IEC TR 61000-3-6:2008IEC 61400-21-1:2019IEC 61000-4-7:2002IEC 61400-21:2001IEC 60050-601:1985EN 50464-3:2007IEC 61400-21:2008IEC 60050-617:2009IEC TR 61000-3-13:2008IEC 61400-27-1All current amendments available at time of purchase are included with the purchase of this document.
