摘要

风能具有随机性，是世界上发展最快、最有前途的可再生能源之一。因此，本文研究了参数不确定性对并网双馈感应发电机(DFIG)风能转换系统(WECS)动态性能的影响。研究中发现的主要不确定参数是互绕组和转子绕组的电抗，这是由于不同风速引起转子角位置的变化而产生的。风速的变化导致发电机转子转速偏差在25% ~ 150%之间。因此，DFIG的转子绕组电抗从其标称值1.31 mΩ变化到0.983 ~ - 0.655 mΩ之间;并且互抗从其标称值0.941 Ω到0.758 ~ - 0.4708 Ω之间。因此，DFIG的定子和转子绕组的电压和电流是不确定的。

Analysis of the effect of parametric uncertainty on dynamic performances of doubly fed induction generator-based wind energy conversion system

The wind, stochastic in nature, is one of the fastest-growing and most promising renewable energy resources in the entire world. Thus, this paper investigates the influence of parameter uncertainties upon a dynamic performance of a grid-tied Doubly-Fed Induction Generator (DFIG)-based Wind Energy Conversion System (WECS). The main uncertain parameters found in the study are mutual and rotor winding reactances which occurred due to the variation of the angular positions of the rotor caused by varying wind speeds. The variation in the wind speed caused the generator rotor speed to deviate between 25% and 150%. Consequently, the rotor winding reactance of DFIG changes from its nominal value of 1.31 mΩ to between 0.983 and −0.655 mΩ; and the mutual reactance from its nominal value of 0.941 Ω to between 0.758 and −0.4708 Ω. As a result, the stator and rotor winding voltages and currents of the DFIG are uncertain.

期刊介绍： Having been in continuous publication since 1977, Wind Engineering is the oldest and most authoritative English language journal devoted entirely to the technology of wind energy. Under the direction of a distinguished editor and editorial board, Wind Engineering appears bimonthly with fully refereed contributions from active figures in the field, book notices, and summaries of the more interesting papers from other sources. Papers are published in Wind Engineering on: the aerodynamics of rotors and blades; machine subsystems and components; design; test programmes; power generation and transmission; measuring and recording techniques; installations and applications; and economic, environmental and legal aspects.
