| 摘 要： | 从能量保持恒定的角度，采用直流侧电压控制方法，对三相动态无功补偿器进行设计。抑制通过对稳定谐波源进行谐波分析，提取其特征谐波进行补偿，可以起到补偿无功和谐波的作用。仿真结果表明，在不对称谐波源情况下，叠加负序分量补偿后的三相系统电流完全对称，并可滤除负荷特征谐波含量。采用上述算法的动态无功补偿器可以通过对负荷的分析，根据负荷及实际的装置进行控制策略调整，具有较大的工程实际意义。

| Abstract: | The control strategy of DC voltage was designed based on energy invariableness on DC voltage.For a harmonic load which contains harmonic with certain characteristic frequencies,the characteristic harmonic current at the certain frequency can also be compensated after analysis on the harmonic load,and it could compensate the reactive power and harmonic together.The simulation results showed that the compensated three-phase currents considering the negative vector were balanced under an unbalanced and harmoni... |
