Certainty. Power grid companies, wind turbine developers and owners, wind turbine manufacturers, wind turbine component suppliers, academic All relevant parties in the wind power industry, such as institutions, research institutes, certification bodies and standardization groups, have the goal of standardizing the harmonic model of wind turbines. need. The standardized harmonic model will be widely used in the design, analysis and optimization of electrical infrastructure for onshore and offshore wind farms. Wind engineering, including wind turbine harmonic performance evaluation, system harmonic research, electrical infrastructure design, and harmonic suppression solution design. Calculation, etc. Standardized wind turbine harmonic model is a performance indicator in large offshore wind farms and other projects involving multiple stakeholders. Grid companies, wind turbine developers and owners, and wind turbine manufacturers should deal with the Harmonic modeling and consensus on harmonic studies for wind farms. Electrical characteristics measurement and Harmonic model and application for evaluating wind turbine generators1 ScopeThis document provides guidelines for the application, construction and recommended requirements of harmonic models for wind turbines. The harmonic models in this document are used It is used to characterize the harmonic emission characteristics of different types of wind turbines under the interaction with the connected power grid. This document provides technical guidance for wind turbine harmonic models and their applications, and specifies in detail the application, structure and verification of harmonic models. This document introduces a consistent understanding of the harmonic characteristics of wind turbines, aiming to make the overall concept of harmonic models easier to understand and implement. Industry recognition (e.g. suppliers, developers, system operators, academia, etc.). This paper proposes a standardized representation method for the harmonic model of wind turbines, which will be widely used in onshore wind power and electrical engineering areas such as electrical infrastructure design, analysis and optimization for offshore wind power. The harmonic model structure of this document will be applicable to. --- To evaluate the harmonic performance of wind turbines during electrical infrastructure design and grid connection studies; --- Used for harmonic research/analysis in modern electrical systems consisting of multiple wind turbines equipped with converters; ---In order to optimize the electrical infrastructure (such as resonant characteristic design) and meet various grid guidelines, it is used for active or passive harmonic filtering Filter design; --- Used to calculate the electrical characteristic parameters of the electrical infrastructure of the wind farm (such as harmonic losses, static reactive power compensation, electrical noise emission, harmonic compatibility levels, etc.); --- Used to evaluate the impact of grid background voltage distortion on wind turbine harmonics; --- Used by relevant parties (such as power grid companies, power generation companies, developers, etc.) to communicate wind turbine harmonic data in a standardized communication interface Interaction; ---Used by engineering software developers to study harmonic characteristics in general interfaces; ---As a test benchmark for wind turbines used in academic research and industrial production. For large power systems with different types of wind turbines connected, such as those connected to the same offshore or onshore booster station, The advantage of using harmonic models to evaluate the standardized harmonic performance of wind turbines is becoming more and more Significant. The wind turbine harmonic model covers the 40th, 50th or 100th harmonic range and can be expanded to higher harmonics according to application needs. times to cover the interharmonic components.2 Normative referencesThe contents of the following documents constitute the essential clauses of this document through normative references in this document.
