摘要

讨论了电力系统中谐波电流和瞬时无功功率补偿样机的试验结果。补偿器由具有瞬时电流控制的脉宽调制(PWM)变换器和比以往用作功率开关器件的闸管关断具有更好开关特性的SI(静态感应)晶闸管组成。SI晶闸管的使用使作者能够开发出一种实用的补偿器，其主电路比以前更紧凑。补偿算法基于瞬时空间矢量实现瞬时功率控制。这允许具有相同配置的硬件通过更改软件来执行多个补偿功能。

A novel compensator using static induction thyristors for reactive power and harmonics

The discussion is presented of the test results of a prototype compensator which compensates for the harmonic currents and instantaneous reactive power in a power system. The compensator is composed of a PWM (pulsewidth-modulated) converter with instantaneous current control and SI (static induction) thyristors which have better switching characteristics than the gate turn-off thyristor which has been used as a power switching device previously. The use of SI thyristors allowed the authors to develop a practical compensator whose main circuit is more compact than before. The compensation algorithm effects instantaneous power control based on the instantaneous spatial vector. This permits the hardware with the same configuration to perform multiple compensating functions by just changing the software.<>
