| Abstract: | 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 forwar... |
