After the improved DFT algorithm is applied, the new algorithm is not influenced by powersystemswing.
采用改进的DFT算法后，算法具有不受系统振荡影响的特点。

The simulation results indicate that the designed fuzzy powersystem stabilizer is better than the conventional fuzzy powersystem stabilizer in suppressing the low-frequency system swing.
仿真结果表明所设计的模糊电力系统稳定器比传统的电力系统稳定器能更有效地抑制系统低频振荡。
