Practical Calculation Method for Harmonic Resonance Analysis of Offshore Wind Farm
摘要
Abstract
The offshore wind farm uses submarine cable for grid-connection but capacitive effect of the cable causes serious problem of harmonic resonance. Therefore,this paper presents a kind of frequency modal analysis method for analyzing harmonic resonance of the offshore wind farm. By means of modeling for elements inside the offshore wind farm,it builds the equivalent harmonic model for the offshore wind farm. Taking one offshore wind farm in Jiangsu province for an exam-ple,it adopts the proposed calculation method for analyzing the harmonic resonance mode inside the wind farm and consid-ers influence of capacity configuration of wind turbines and installation position of the reactive power compensation equip-ment so as to verify feasibility of the proposed method. The results prove this proposed calculation method combines advan-tages of the modal analysis method and the frequency scanning method,so it can not only effectively determine influencing area of harmonic resonance,but also improve calculation efficiency.关键词
