摘 要: 介紹了晶閘管控制電抗器(TCR) 型無功補償裝置的各次諧波電流表達式,推導(dǎo)得到了電抗器電感量計算公式,分析了諧波無功功率與基波無功功率之間的關(guān)系。通過分析發(fā)現(xiàn)晶閘管控制電抗器諧波損耗在控制角α為140時與基波無功功率之比最大,在控制角α為102時最小,電抗器總無功功率在控制角α為102時最大,按照此時工況計算電抗器電感量能夠保證TCR 安全運行。

Abstract: This paper introduced the expression of different harmonic current in thyristor controlled reactor (TCR) reactive compensation device and deduced the inductance formula of reactor. Analysis was made to the relationship between harmonic wave var and fundamental wave var. The results show that the ratio of harmonic wave loss to fundamental wave var is the biggest one at 140。control angle, while the ratio of that is the smallest one at 102。control angle. The total reactive power is the biggest one at 102。control angle. According to the working conditions, the calculation of reactor inductance can ensure safe operation of TCR.
Key words: thyristor controlled reactor; dynamic var compensation; harmonic; inductance
