Presentation / Conference Contribution
Xiao, Y., Zhao, W., Chen, L., Huang, S., & Wang, Q. (2016, September). Fast quasi-synchronous harmonic algorithm based on weight window function- mixed radix FFT. Presented at IEEE International Workshop on Applied Measurements for Power Systems, Aachen, Germany
According to the requirements of IEC61850-9-2LE, digital energy metering devices mainly adopt 80×fr fixed sampling rate. When the harmonic analysis is carried out under asynchronous sampling, it will produce large errors due to spectral leakage. Quas...
