摘要
给出了利用电力系统模块(PSB)工具箱对仿真波形进行频谱分析的一种新方法。该方法以MATLAB提供的PSBFFT SCOPE函数为基础,对其输入变量加以改造,克服了其不能应用于变步长算法模型频谱分析的缺陷,拓宽了在PSB工具箱中进行频谱分析的范围。实际仿真结果表明,该方法分析正确,使用简捷,在实际仿真过程中是切实可行的。
A new method of frequency spectrum analysis using Power System Blockset （PSB） is presented. Based on the PSBFFT- SCOPE function supplied by MATLAB, the input variable is reformed. This method can overcome the defect that the function can not be used to analyse the frequency spectrum of such signals sampled at variable step. And then the spectrum analysis range has been broaden in the PSB. The simulation results are accurate and indicate that the new method is feasible.
