本文研究了一种用于三相电压型并网逆变器的新型直接功率控制策略——预测直接功率控制（Predictive Direct Power Control，简称P-DPC）。重点讨论了P-DPC不同的电压矢量选择原则和电压矢量作用时间的处理方法，以降低低次电流谐波成分，获得更好的动、静态性能。(In this paper, a new direct method for three-phase voltage power grid-connected inverter control strategy- predictive direct power control (Predictive Direct Power Control, called P-DPC). Focused on the P-DPC different voltage vector selection principles and action time voltage vector processing method to reduce the low current harmonics components, better dynamic and static performance.)
