摘要

传统的静态无功补偿器(SVCs)采用并联电抗器和电容器。这些标准无功功率分流元件被控制以产生快速和可变的无功功率。诸如晶闸管等电力电子器件用于根据系统情况将它们切换到所连接的网络中或切换出网络。有两种基本类型,即晶闸管控制电抗器(TCR)和晶闸管开关电容器(TSC)。在本文中,我们希望研究一种用串联电阻和电抗器(R-L)代替电抗器或电容器的补偿器。导出了补偿器的性能方程,并将其应用于每种结构的补偿器特性。对他们的表演进行了比较,并展示了他们之间的对比。所有三种配置都是为了在系统中实现统一的功率因数。

An R-L Static Var Compensator (SVC)
Traditional static var compensators (SVCs) employ shunt reactors and capacitors. These standard reactive power shunt elements are controlled to produce rapid and variable reactive power. Power electronic devices like the thyristor etc. are used to switch them in or out of the network to which they are connected in response to system conditions. There are two basic types, namely the thyristor-controlled reactor (TCR), and the thyristor-switched capacitor (TSC). In this paper we wish to investigate a compensator where the reactor or capacitor is replaced by a series connected resistor and reactor (R-L). The performance equations are derived and applied to produce the compensator characteristics for each of the configurations. Their performances are compared, and the contrasts between them displayed. All three configurations are made to achieve unity power factor in a system.
