【摘要】：六相電勵磁同步風(fēng)力發(fā)電機(jī)(SP-EESWG)是一種特殊的變速恒頻風(fēng)電機(jī)組。以風(fēng)電機(jī)組各部分的數(shù)學(xué)模型為基礎(chǔ),詳細(xì)考慮風(fēng)力機(jī)的風(fēng)能利用特性、整流-逆變電路的穩(wěn)態(tài)特性,以及機(jī)組所采用的最大風(fēng)能跟蹤控制、直流電容電壓控制和并網(wǎng)逆變器控制對穩(wěn)態(tài)特性的影響,建立了SP-EESWG的穩(wěn)態(tài)模型,并將其應(yīng)用于含SP-EESWG電網(wǎng)的潮流計算。最后,以單機(jī)無窮大系統(tǒng)和IEEE 14節(jié)點(diǎn)系統(tǒng)兩個算例驗證了所提模型的正確性和有效性。仿真結(jié)果表明,不同風(fēng)速情況下,現(xiàn)有文獻(xiàn)廣泛采用的風(fēng)電機(jī)組簡化潮流模型與該模型的計算結(jié)果均有不同程度的誤差。其中,一階和二階簡化模型的誤差較大,不宜用于SP-EESWG的穩(wěn)態(tài)特性分析;當(dāng)風(fēng)速處于額定風(fēng)速附近時,三階簡化模型與該模型的誤差可以忽略。
[Abstract]:SP-EESWG is a special variable speed constant frequency wind turbine. Based on the mathematical model of each part of wind turbine, the characteristics of wind power utilization, the steady-state characteristics of rectifier inverter circuit and the maximum wind energy tracking control are considered in detail. Based on the influence of DC capacitor voltage control and grid-connected inverter control on steady state characteristics, the steady state model of SP-EESWG is established and applied to power flow calculation of power grid with SP-EESWG. Finally, two examples of single-machine infinite bus system and IEEE 14-bus system are given to verify the correctness and validity of the proposed model. The simulation results show that the simplified power flow model of wind turbine widely used in the existing literature and the calculation results of the model have different degrees of error under different wind speeds. The errors of the first and second order simplified models are too large to be used to analyze the steady state characteristics of SP-EESWG, and the errors between the third order simplified model and the SP-EESWG model can be neglected when the wind speed is near the rated wind speed.
