通过对两种低频振荡分析方法的讨论,阐明了电力系统低频振荡的数学特征;并进一步探究了低频振荡的负阻尼机理和共振机理,综合对比分析这两种机理的区别,揭示了低频振荡的本质和诱发振荡的根本原因,探讨了针对不同机理产生的低频振荡的具体抑制方法,为低频振荡的抑制提供了详细的参考策略,保障电力系统稳定运行。
In this paper, two kinds of low-frequency oscillation analysis method are discussed, and mathematical characteristics of low-frequency oscillation in power system is illustrated. Mechanism of negative damping and resonance mechanism of low- frequency oscillation arc further explored, and the differences between these two mechanisms are comprehensively compared and analyzed. The nature of low-frequency oscillations and root causes of induced oscillation are given. Therefore, the specific suppressing methods for low-frequency oscillation that is generated by different mechanisms are described, and the detailed reference strategy for the low-frequency oscillations suppression is provided, which would stabilize the operation of power systems.
