利用旁路阻尼滤波器抑制次同步谐振:原理与应用
|
摘要
通常意义上的次同步谐振包括3方面的内容,即感应发电机效应、扭振相互作用和暂态扭矩放大效应。旁路阻尼滤波器(bypassdampingfilter,BDF)通常被认为仅对感应发电机效应有抑制作用。首先通过定性和定量分析说明BDF同样能够有效抑制扭振相互作用和暂态扭矩放大效应。接着从扭振稳定性的角度出发,针对单机系统和多机系统分别提出了BDF的参数整定方法。最后基于IEEE第一标准模型和我国华北地区某20机等值模型,通过时域仿真和扭振模式分析验证了BDF对扭振相互作用和暂态扭矩放大效应的抑制效果,以及所提出参数整定方法的有效性。
Generally, subsynchronous resonance(SSR) has three categories, namely induction generator effect, torsional interaction and transient torque amplification. Bypass damping filter(BDF) is generally supposed particularly effective for induction generator effect. This study shows that BDF is also an effective countermeasure against torsional interaction and transient torque amplification. The mechanism of BDF in suppressing SSR is analyzed qualitatively and quantitatively. Then BDF parameter tuning methods for simple and complex systems are proposed respectively based on torsional stability analysis. SSR damping effectiveness for BDF is verified in IEEE first benchmark model and a twenty-generator series-compensated system through torsional mode analysis and time-domain simulation.
