基于單相牽引變壓器和潮流控制器,提出了一種組合式同相供電系統(tǒng)。在這個(gè)新系統(tǒng)中,由單相牽引負(fù)載引起的電網(wǎng)側(cè)電能質(zhì)量問(wèn)題被解決,同時(shí)牽引變電所出口處的電分相被取消,電力機(jī)車可以獲得持續(xù)的電能。利用功率傳遞關(guān)系,建立了系統(tǒng)的數(shù)學(xué)模型。基于功率平衡原理,計(jì)算了潮流控制器的補(bǔ)償電流。根據(jù)電能質(zhì)量國(guó)家標(biāo)準(zhǔn),提出了優(yōu)化地部分補(bǔ)償策略來(lái)代替既有的完全補(bǔ)償。此外,潮流控制器實(shí)現(xiàn)該算法的限制大大低于以往的研究結(jié)果。通過(guò)大量的仿真驗(yàn)證了補(bǔ)償算法和控制技術(shù)的合理性,本文分析內(nèi)容驗(yàn)證了該系統(tǒng)的可行性。
