【摘要】：大容量光伏電站并網(wǎng)時會對電網(wǎng)穩(wěn)定性產(chǎn)生較大影響。以實際工程為例,建立光伏電站等元件的數(shù)學模型,對大容量光伏發(fā)電項目接入電網(wǎng)的相關(guān)技術(shù)問題進行研究;實現(xiàn)對其并網(wǎng)時系統(tǒng)的穩(wěn)定性進行仿真分析,評估光伏電站并網(wǎng)運行后對電網(wǎng)電壓、潮流等的影響,采用切實可行的無功補償方案,并提出可行的解決方案以保證光伏電站及電網(wǎng)的安全穩(wěn)定運行。
[Abstract]:When large capacity photovoltaic power stations are connected to the grid, it will have a great impact on the stability of the power grid. Taking the actual project as an example, the mathematical model of photovoltaic power station and other components is established, and the related technical problems of large capacity photovoltaic power generation project connected to the power grid are studied. The stability of the system is simulated and analyzed, the influence of photovoltaic power station on grid voltage and power flow is evaluated, the feasible reactive power compensation scheme is adopted, and the feasible solution is put forward to ensure the safe and stable operation of photovoltaic power station and power grid.
