| 摘 要： | 在学术界有关无功功率理论的争论由来已久 ,却至今未取得统一认同。本文试提出了一种基于内积空间的空间矢量无功功率理论 ,给出了有功及无功电流空间矢量和瞬时有功、无功电流以及瞬时有效、无效电流等各种量的定义 ,同时阐明了该理论的明确物理意义。然后给出了实际应用中各种电流的数字化检测方法 ,最后针对检测方法进行了仿真研究。实验结果证明了理论的正确性。

| Abstract: | The argument about the theory reactive power has appeared since 1920's.Traditional power theory cannot be applied into circuit under non-sinusoidal conditions.And the new available instantaneous power theories have no clear physical meanings in some typical conditions.To solve these problems,a new theory of space vector recative power is presented.And instantaneous reactive current and instantaneous active current are defined,which is based on the new theory.Then the specific physical meaning is discussed in datail.Later,digital algorithms for calculationg various sort of crrent are given.Finally,simulation for the currents calculation in based on the proposed theory is carried out and results confirm the theoretical analysis. |
