Traditional wind turbines are commonly equipped with induction generators because they are inexpensive, rugged, and require very little maintenance. Unfortunately, induction generators require reactive power from the grid to operate，capacitor compensation is often used. Because the level of required reactive power varies with the output power, the capacitor compensation must be adjusted as the output power varies. The interactions among the wind turbine, the power network, and the capacitor compensation are important aspects of wind generation that may result in self-excitation and higher harmonic content in the output current. This paper examines the factors that control these phenomena and gives some guidelines on how they can be controlled or eliminated ......

風(fēng)力發(fā)電中的自我激勵與諧波

1．介紹
傳統(tǒng)的風(fēng)力渦輪機(jī)通常安裝的是感應(yīng)發(fā)電機(jī)，因?yàn)樗畠r，耐用，而且只需要很少的維護(hù)。然而，電感應(yīng)發(fā)電機(jī)需要的無功功率通常通過電容器補(bǔ)償來得到。因?yàn)檩敵龉β矢鞑幌嗤噪娙菅a(bǔ)償必須隨之調(diào)整。風(fēng)力發(fā)電機(jī)組的電力網(wǎng)絡(luò)中，相互的電容補(bǔ)償作用是導(dǎo)致輸出電流中產(chǎn)生自我激勵和高次諧波的一個重要原因。這篇文章探討產(chǎn)生這些現(xiàn)象的原因，并對如何控制或消除這些現(xiàn)象提出一些方法。
