摘要：
瞬时无功功率理论(p-q理论)是基于a-b两相坐标系而提出的，所有的功率分量也是在a-b两相坐标系中定义的，这使其理解起来比较困难。以瞬时无功功率理论为基础，给出了a-b坐标系中的各功率分量与三相系统中补偿电流的对应关系。然后对有源电力滤波器控制策略中的相关问题进行了详细的理论分析与公式推导，解决了在控制策略选择过程中遇到的理论问题。 |

Abstract:
On the basis of a-b coordinate system, the instantaneous reactive power theory, i.e., the p-q theory, is proposed, so all power components in p-q coordinate system are defined in a-b coordinate system, so it makes the understanding of power components in p-q coordinate system difficult. Based on instantaneous reactive power theory, the corresponding relations between power components in a-b coordinate system and compensating currents in three-phase system are given; then detailed theoretical analysis and formula derivation of related problem in the control strategy for active power filter are carried out to solve the theoretical problem encountered in the selection of control strategy. |
