對用于變速恒頻鼠籠異步風(fēng)力發(fā)電機系統(tǒng)的并聯(lián)變流器（補償器）的容量優(yōu)化問題進行了研究。基于風(fēng)力機特性和發(fā)電機空載特性，求得發(fā)電機運行的轉(zhuǎn)速范圍以及各轉(zhuǎn)速下的最大負載，計算各轉(zhuǎn)速下空載和最大負載時維持額定電壓所需要的無功功率，之后通過對建壓電容值的適當(dāng)選取，確定補償器的最小容量。
Abstract: The optimization of the capacity of the parallel converter used in a variable-speed constant-frequency cage induction wind power generator system is investigated. By utilizing the characteristics of the wind turbine and the generator, the speed range of the generator and its maximum loads at different speeds are determined, and then the reactive power to maintain the rated voltage with no-load and maximum load at different speeds is calculated. Thus the minimum capacity of the converter can be found by adequately choosing the capacitance value of the voltage build-up capacitor.
