| 摘 要： | 鉴于现有的无功谐波补偿装置的不足，提出一种新的负序无功补偿方法。它利用序导纳矩阵来计算补偿导纳，用晶闸管控制电抗器（TCR）与电容器并联来实现此补偿导纳，从而构成负序无功补偿装置。实例分析表明，该补偿装置所需设备容量不大，补偿效果好。

| Abstract: | In view of the shortage in existing reactive harmonic compensation, a new compensation method is put forward. Its compensation bases on reactive power negative sequence impedance. The compensation admittance is calculated via sequence admittance matrix. By thyristor controlled reactor （TCR） parallel connecting with capacitor banks, this calculated compensation admittance can be achieved, and thus the device is formed. Analyzing a practical example shows that the capacity of this compensation device is small but results good effect. |
