摘要
能否滤除衰减的直流分量是衡量保护算法抗干扰能力的重要特征。在对傅里叶算法及其改进算法分析的基础上,通过大量的仿真计算并在TMS320C32上进行了对比实验,对不同算法滤除谐波和衰减直流分量的能力进行了分析和比较,最后给出了结论。
A protection algorithm can be judged as a strong capability of anti-interference one if it can eliminate decaying DC components. On the analysis of Fourier algorithm and improved Fourier algorithm, this paper performs simulation calculations employing all kinds of algorithms and does comparison experiment on TMS320C32 DSP. After analyzing and comparing the ability of eliminating harmonic current and decaying DC components, the paper proposes the optimal algorithm for computer-based protection of power system.
