摘要
在对大型光伏电站并网运行特性理论研究和实验分析的基础上,建立了双级变换并网光伏电站整体模型,并分析了光伏电站的动态输出特性和等值阻抗。然后以某1.6 MW实际并网光伏电站工程为算例,着重研究了光伏电站接入配网对系统潮流、母线电压、短路电流和继电保护等方面的影响。
Based on the in-depth theoretical study and experimental analysis of the photovohaic power plant, the overall model of the MW PV power station is established and the dynamic output characteristics of the photovohaic power station and the equivalent impedance are analyzed. Furthermore, the effects on the local distribution system are studied through an example of a distribution network connected with a 1.6 MW PV power, with focus on power flow distribution, bus voltage, and short circuit current and relay protection and so on.
