    摘要:

    提出一種基于發(fā)電廠的風(fēng)力發(fā)電機(jī)設(shè)計(jì)理念，以風(fēng)電場(chǎng)年發(fā)電量和發(fā)電質(zhì)量作為優(yōu)化目標(biāo)，采用伸縮式葉片結(jié)構(gòu)，在低風(fēng)速下伸展葉片以提高風(fēng)機(jī)輸出功率，在高風(fēng)速下收縮葉片，結(jié)合變槳實(shí)現(xiàn)輸出功率調(diào)節(jié)；將額定風(fēng)速、伸展時(shí)最大葉片長(zhǎng)度、收縮時(shí)最小葉片長(zhǎng)度和葉片中心半徑作為優(yōu)化變量，建立風(fēng)機(jī)系統(tǒng)優(yōu)化模型，運(yùn)用遺傳算法獲取風(fēng)機(jī)最優(yōu)設(shè)計(jì)參數(shù)。結(jié)合風(fēng)機(jī)設(shè)計(jì)實(shí)例，驗(yàn)證了風(fēng)機(jī)系統(tǒng)優(yōu)化設(shè)計(jì)的可行性。

    Abstract:

    A design method of wind energy conversion system based on the concept of power factor is proposed. The optimal power energy and electricity quality are considered as optimization objects. The blades are extended to improve power out-put at low wind speed and shrunk with regulating mechanism at high wind speed to adjust power out-put. Taking the rated wind speed, the maximal length of an extended blade, the minimal length of a shrunk blade and the central radius of a blade as optimization variables, an optimization model of the wind turbine is proposed to obtain optimal design parameters using genetic algorithm. Finally, the availability of optimal design of wind energy conversion system is validated by a case of wind turbine. 
