摘要
由于公共电网中非线性负载大量增加,从而产生大量危害电力设备及电能质量的电力谐波。为了有效地检测电力谐波,并对其进行治理,本文将DSP与LabVIEW虚拟仪器技术相结合,提出了一个谐波实时测量分析仪的设计方案,同时给出了系统的硬件构成和谐波分析算法,以及LabVIEW子程序的详细设计及实现。模拟实验表明,该方案设计的分析仪测量精确度高、实时性好、人机界面友好,且便于扩展。
A large amount of power harmonic is generated due to the increase of nonlinear load in a power system. The power harmonic is harmful to the power system and instrument. However, harmonic analysis lays the foundation for power harmonic treatment. The paper discusses the development of a power harmonic analyzer based on DSP and LabVIEW, which is used to analyze and measure harmonic on real-time. The analyzer' s hardware, harmonic analysis algorithm, LabVIEW software design and the implementation are all brought forward in detail. Experiments show that the analyzer has high measurement accuracy, good real-time performance, friendly man-machine interface and convenient system extension features.
