摘要
介绍了基于现行电力系统中较流行的可控串补(TCSC)技术,降压后在低压侧利用电力电子器件实行的无功无级柔性补偿。该补偿模块的特点是它既能消除自身因电力电子器件而产生的谐波,又能有效解决高压系统中晶闸管的耐压使用问题。模块吸收连续可调的无功与有级电容共同作用能实现整个系统的无级柔性补偿,有效解决现行系统中有级投切振荡、不易控制等问题。该模块分相设计,可在一定范围内补偿三相不对称系统。
This system, based on TCSC compensation technology which is widely used nowadays in power system, can accomplish reactive power flexible compensation by using power electronic device at lower voltage side after voltage reduction. The particular feature of this compensation module is that it not only eliminates harmonics arising itself from electronic elements, but can also solve the problem of TCR voltage withstand effectively. This module can be designed from phase to phase and solve the problem of over or under compensation to realize balanced flexible compensation for tri-phase asymmetry load in a certain scale.
