摘　　要：谐波和无功检测是进行谐波抑制和无功功率补偿的关键技术。本文详细分析了三相瞬时无功功率理论下的谐波电流和无功电流检测,并利用Matlab软件建立了谐波检测的仿真模型,进行了计算机仿真实验。仿真实验结果表明:该方法可以准确及时地检测出三相电路中的谐波电流和无功电流。Detection of harmonic and reactive current is very crucial to harmonic restraint and reactive compensate. By using MATLAB, simulation model is built based on instantaneous reactive power theory. Through the model we can make computer simulation. The result shows that this model can exactly detect harmonic and reactive current in time.
