| 摘 要： | 本文分析了不平衡电网电压条件下三相电压型PWM整流器的控制策略,研究了基于功率平衡的控制策略,以消除直流电压二次谐波。船舶电网不平衡时,线路阻抗的功率不平衡,当电网不平衡功率完全被线路阻抗吸收时,整流器桥侧的功率则恒定平衡,这给消除直流电压二次谐波带来便利。本文最后进行了仿真及原理样机验证,试验结果与理论分析一致。

| Abstract: | The control strategy in unbalanced power grid for three-phase voltage source PWM rectifier is investigated in the paper. The control strategy based on power balance is researched to eliminate the second harmonic of DC voltage. The power of the transmission line impedance is unbalanced when the power grid is unbalanced. And the power at the arm side for PWM rectifier keeps balance when the unbalanced power in grid is absorbed completely by the transmission line impedance. Thus the effective measures can be obtained to eliminate the second harmonic of DC voltage. Finally, the simulation and the test of prototype are implemented, and the experimental results agree with theoretic analyses. |
