| Abstract: |
| The virtual instrument(VI)technology is applied to measure power harmonics.On the development platform of Lab Windows/CVI,a harmonic meter based on VI is developed and its performance is better than traditional instrument.The working principle,HW & SW construction,design concept and technical points are detailed.It is pointed out that the higher functions of harmonics can be further developed using this harmonic meter,such as harmonic data measuring,harmonic database establishment,harmonic power flow calculation,harmonic resonance analysis,harmonic simulation,etc. |
