【摘要】 实时、准确地检测出电网中的谐波电流和无功电流是进行谐波抑制和无功补偿的关键。本文在三相瞬时无功功率理论的基础提出了一种改进的单相无功电流检测算法,并建立了仿真模型,仿真结果表明:该算法可以及时、准确地检测出三相电路中的谐波电流和无功电流,同时也验证了此算法在DSP系统中的可行性。更多还原

【Abstract】 Detection of harmonic and reactive current is crucial to harmonic restraint and reactive compensation.The paper introduces an improved harmonic and reactive current detecting method based on there-phase reactive current using instantaneous reactive power theory.By using matlab,simulation model is built,and the results show that this model can exactly detect harmonic and reactive current in time and it is feasible in DSP system.更多还原
