摘 要: 介绍了晶闸管控制电抗器(TCR) 型无功补偿装置的各次谐波电流表达式,推导得到了电抗器电感量计算公式,分析了谐波无功功率与基波无功功率之间的关系。通过分析发现晶闸管控制电抗器谐波损耗在控制角α为140时与基波无功功率之比最大,在控制角α为102时最小,电抗器总无功功率在控制角α为102时最大,按照此时工况计算电抗器电感量能够保证TCR 安全运行。

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
