ABSTRACT: Although the installation capacity of wind
turbines in our country has e the number one in the
world, but there are a number of unpredictable problems, which
might e the key issues in the grid-connected operation
owing to lack of long-period operation experience. To meet the
grid-code requirements, it is necessary to deeply discuss the
indispensable control strategy and protection measure for the
grid-fault ride-through operation. This paper, taking aim at the
Doubly-Fed Induction-Generator (DFIG), makes a thorough
summarization and investigation on some hot-spot issues in the
grid-connected operation, especially under the grid-fault
condition, which include low voltage ride through (LVRT),
Crowbar technique, asymmetric grid-fault ride-through
operation and related new controller design, for the purpose of
enhancing the grid-connected operating ability of wind-turbine
under weak grid condition in our country.
KEY WORDS: doubly-fed induction generator (DFIG);
grid-connected operation; grid code; low-voltage right-through;
unsymmetrical grid fault; proportional-integral-resonant (PI-R)

摘要:目前我国风电装机容量已跃居世界首位,但因缺乏长
期运行经验,在追赶和跳跃式发展中未能预见并网运行中的
诸多问题,已成为其发展瓶颈。为满足电网规范要求的电网
故障下不脱网运行,必须深入研讨所需控制策略和保护方
