针对由电网不对称引起的Vienna整流器有功功率波动和电流不对称问题，介绍了有功功率波动的抑制控制APFSC（active power fluctuation suppression control）和对称的正序电流控制SPSCC（symmetric positive-sequence current control）。由于受到功率器件的电流限制，采用APFSC会导致Vienna整流器运行的最大有功功率降低；采用SPSCC可以扩展Vienna整流器运行的最大有功功率，但有功功率波动较大。基于此，提出1种改进的功率控制IPC（improved power control）策略。当Vienna整流器处理功率较小时，以保持有功功率无波动为首要目标，此时IPC与APFSC的效果一致，对比SPSCC，IPC可有效抑制有功功率的波动；当Vienna整流器处理功率较大时，以满足功率需求为首要目标，但尽可能地减小有功功率波动，此时APFSC无法满足功率需求，但IPC可以满足有功功率需求，且在满足功率需求的前提下，对比SPSCC，IPC下有功功率的波动更小。最后通过实验验证了控制方法的优越性。

Aimed at the problems of active power fluctuation and current asymmetry of a Vienna rectifier caused by asymmetric grid, active power fluctuation suppression control (APFSC) and symmetric positive-sequence current control (SPSCC) are introduced. Due to the current limitation of power devices, the use of APFSC will reduce the maximum active power of the Vienna rectifier. In comparison, the use of SPSCC can expand its maximum active power at the cost of significant active power fluctuation. With the comprehensive consideration of disadvantages of the above two methods, an improved power control (IPC) strategy is proposed. When the processing power of the Vienna rectifier is small, keeping the active power without fluctuation is the primary control target. In this case, the effects of IPC and APFSC are the same. The active power fluctuation under IPC is effectively suppressed, while that under SPSCC is large. When the processing power of the Vienna rectifier is large, meeting the power demand is the primary control target, but the active power fluctuation should be reduced as much as possible. Under this circumstance, IPC can meet the active power demand, but APFSC cannot meet the power demand. On the premise of meeting the power demand, the fluctuation of active power under IPC is smaller than that under SPSCC. Finally, experimental results verified the advantage of the proposed control method.
