Summary:For non-sinusoidal frequency conversion signal in AC drive traction system, its variation range of amplitude and frequency is wide, and harmonic content is large. In order to accurately and quickly calculate the characteristic values of the signal, this paper firstly introduced the basic principle of an AC drive test system, then analyzed in detail and test the data processing algorithm for full cycle fast interception, whole cycle number selection, harmonic analysis and power calculation, and the results show that the degree of software data processing accuracy is of 1 ‰. The field test results verified that the relative error of the calculated active powers between the test system and the power analyzer is within 5‰, and the system accuracy meets the standard requirements.
