【摘要】：正低频振荡与次同步振荡是电力系统的经典问题之一,随着同步电网规模的扩大、固定串联电容补偿输电技术和柔性交流输电技术的大范围应用以及大规模新能源接入电网,目前低频振荡与次同步振荡问题仍然是迫切需要解决的重大工程问题,而且这两方面的问题又呈现出新的特征。总体上看,对于低频振荡与次同步振荡问题,不管是在理论上还是在工程实践上,都还没有完全解决。主要表现在四个方面:1物理机理上的挑战;2分析方法上的挑战;3实时监测上的
[Abstract]:Moderate low frequency oscillation and sub synchronous oscillation are one of the classical problems in power system. With the expansion of synchronous power grid, the wide application of fixed series capacitor compensation transmission technology and flexible AC transmission technology, and the large-scale new energy access to the power grid. At present, the problems of low frequency oscillation and subsynchronous oscillation are still important engineering problems that need to be solved urgently, and these two problems show new characteristics. In general, the problem of low frequency oscillation and sub synchronous oscillation has not been completely solved either in theory or in engineering practice. There are four main aspects: (1) challenges in physical mechanism; (2) challenges in analytical methods; (3) challenges in real-time monitoring.
