Solutions for Interharmonics in Variable Speed Drives for LNG Plants

, 2011
Variable speed drives can cause components of any frequency known as interharmonics. Large variable speed drives in the order of tens of megawatts can replace Gas Turbines in driving cooling compressors in a Liquefied Natural Gas Plant.

Comparisons of the execution times and memory requirements for high-speed discrete fourier transforms and fast fourier transforms, for the measurement of AC power harmonics

, 2011
Conventional wisdom dictates that a Fast Fourier Transform (FFT) will be a more computationally effective method for measuring multiple harmonics than a Discrete Fourier Transform (DFT) approach.
