【摘要】:隨著光伏發(fā)電技術的不斷發(fā)展,孤島運行故障問題日益突顯出來,會對設備和人身安全帶來一定危害,因此必須有效快速檢測孤島運行狀態(tài)以保證電力系統安全穩(wěn)定運行。本文詳細分析了主動頻率偏移孤島檢測原理,基于此提出了一種新型光伏發(fā)電主動頻率偏移孤島檢測方法 ,該方法可減小檢測盲區(qū)和快速準確檢測孤島故障。在Matlab/Simulink軟件中建立了仿真模型,對所提方法進行了驗證,并詳細分析了仿真結果。
[Abstract]:With the continuous development of photovoltaic power generation technology, the problem of isolated island operation fault becomes increasingly prominent, which will bring certain harm to equipment and personal safety. Therefore, it is necessary to effectively and quickly detect the island operation state to ensure the safe and stable operation of power system. In this paper, the principle of active frequency offset islanding detection is analyzed in detail. Based on this, a new active frequency offset islanding detection method for photovoltaic power generation is proposed, which can reduce the blind area and detect the isolated island fault quickly and accurately. The simulation model is established in Matlab/Simulink software, the proposed method is verified, and the simulation results are analyzed in detail.
