CPC功率理论的一种新的时域观点:单相系统
A Novel Time-Domain Perspective of the CPC Power Theory: Single-Phase Systems
摘要:
本文提出了一种新的时域观点的电流的物理成分(CPC)功率理论的单相系统在非正弦条件下运行。建议CPC分解揭示了一些有吸引力的物理特性的负载电流分量的可测量的功率分布在负载网络中的分支。在无功电流的时域等效中的工具是Iliovici无功功率的概念,其是在绘制电流对电压时由Lissajous图形成的回路的面积的量度。对于正弦系统,Iliovici的无功功率积分包含在IEEE标准的功率定义中。此外,无功电流被分解成两个新的电流,代表有功电流和散射电流的无功对应物。
英文摘要:
This paper presents a novel time-domain perspective of the Currents' Physical Components (CPC) power theory for single-phase systems operating under nonsinusoidal conditions. The proposed CPC decomposition reveals some appealing physical characteristics of the load current components in terms of measurable powers that are distributed over the branches in the load network. Instrumental in the time-domain equivalent of the reactive current is the concept of Iliovici's reactive power, which is a measure of the area of the loop formed by the Lissajous figure when plotting the current against the voltage. For sinusoidal systems, Iliovici's reactive power integral is included in the IEEE Standards on power definitions. Furthermore, the reactive current is decomposed into two new currents that represent the reactive counterparts of the active and scattered current.
