变压器阻抗与无功补偿装置容量的选择

Choice of transformer impedance and capacitance of var power device

从调节变压器分接头、高阻抗变压器、无功负荷等三个方面分析对负载端电压的影响,阐述电力系统的无功平衡对维持电压水平的重要性,并说明使用高阻抗变压器(或变压器负载侧出口处)串联电抗需增加无功补偿容量的原因。

This paper analyzes the effect of adjusting transformer＇s tap, high impedance transformer, non-capacity load on load voltage, expounds the importance of non-capacity balance to voltage maintaining explains the reason for the need of increasing non-capacity complementary device in using high impedance transformer.
