| 摘 要： | 为研究大型光伏电站并网适应性,以某地区三个百兆级光伏电站并网工程为例,根据该地区最大、最小负荷运行方式下的数据,利用DIgSILENT/Power Factory软件,在光伏电站不同出力条件下对电网的潮流大小、母线电压波动、安全性N-1等方面进行仿真。依据相关导则要求,对大型光伏电站并网时适应性进行研究分析。针对大型光伏并网时母线电压降低幅度过大的现象采取相应的补偿措施,提高光伏电站并网适应性。该分析可对以后的工程提供参考。

| Abstract: | In order to analyze on the adaptability of the large-capacity grid-connected PV station, this paper takes the hundred-billion grade project in Mangya for example. According to the maximum and minimum load operation data of Mangya, the power flow, bus voltage fluctuation, and N-1 security are simulated by using DIgSILENT/Power Factory software. According to the guideline, the adaptability of large-scale grid-connected PV station is studied and analyzed. The compensation method is proposed to improve the phenomena that the bus voltage drop amplitude is too large when large-scale PV grid connection. The adaptability of large-scale grid-connected PV station is improved. The analysis provides a reference for other engineering.
