【摘要】:正低頻振蕩與次同步振蕩是電力系統(tǒng)的經(jīng)典問題之一,隨著同步電網(wǎng)規(guī)模的擴大、固定串聯(lián)電容補償輸電技術和柔性交流輸電技術的大范圍應用以及大規(guī)模新能源接入電網(wǎng),目前低頻振蕩與次同步振蕩問題仍然是迫切需要解決的重大工程問題,而且這兩方面的問題又呈現(xiàn)出新的特征。總體上看,對于低頻振蕩與次同步振蕩問題,不管是在理論上還是在工程實踐上,都還沒有完全解決。主要表現(xiàn)在四個方面:1物理機理上的挑戰(zhàn);2分析方法上的挑戰(zhàn);3實時監(jiān)測上的
[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.
