RESEARCH INITIATION AWARD: Simulation of Nonsinusoidal Waveform Propagation in Distribution System Using Fast Real Transforms

9410183 OlejNiczak本项目研究用于电能质量评估的新的频域分析方法。研究了Hartley变换作为电力系统周期稳态解的一种替代方法，该方法由电力系统的正弦稳态等值来建模。由于快速哈特利变换(FHT)是计算效率最高的线性或时域卷积的频域算法，因此可以高效、准确地计算电力系统对非正弦激励的响应。期望这项研究的结果可以导致新的实值分量模型和结构化矩阵，这些模型和结构矩阵可能服从稀疏性和并行处理技术。***

9410183 Olejniczak This project investigates new frequency-domain analysis methods for electric power quality assessment. The Hartley transform is studied as an alternative methodology for the periodic steady- state solution of electric power systems modelled by their sinusoidal steady-state equivalents. Since the fast Hartley transform (FHT) is the most computationally-efficient frequency- domain algorithm for performing linear or time-domain convolution, the power system response to nonsinusoidal excitations may be calculated efficiently and accurately. It is expected that the results of this research may lead to new real- valued component models and structured matrices which may be amenable to sparsity and parallel-processing techniques. ***
