摘要：
The current hardware detection methods have many drawbacks, such as poor flexibility and single function. Considering the frequency fluctuation and half-wave symmetric characteristic of the metro power system signals, an improved FFT algorithm that only analyzes the odd harmonics in its calculation is presented and just has a half amount of the traditional FFT. On this basis, the metro power harmonic detection system was developed based on virtual instrument. The PC-DAQ structure scheme was adopted for hardware of this system. The software of this system was developed based on LabVIEW2009. The tests show that this system can achieve the expecting functions and has the high accuracy.
