摘要
本文介绍了瞬时无功功率理论在谐波和无功电流实时检测方面的应用。利用Matlab仿真软件,对基于瞬时无功功率理论谐波检测方法进行了仿真研究,并对仿真结果进行了较为详细地分析,仿真结果表明:基于瞬时无功功率理论谐波检测方法可以准确、实时地检测出三相电流中的谐波电流及无功电流,可为抑制谐波和无功补偿提供可靠的谐波及无功电流分量。
Instantaneous reactive power theory applied on harmonic and reactive current real-time detection is presented in this paper. With Matlab simulation software, a research on simulation of harmonic detection means based on instantaneous reactive power theory is carried out, and a detailed analyse of the simulation result is presented. The result indicates: the harmonic detection means based on instantaneous reactive power theory can detect harmonic and reactive component in three-phase current precisely and real-time, to supply reliable harmonic and reactive current for harmonic restraint and reactive power compensation.
