摘要
以桃子光伏电站并网工程设计为例,研究如何合理选择光伏电站并网点。结合相关背景资料,给出两种桃子光伏电站66 kV出线接入系统的方案,方案一为接入66 kV永大线,方案二为接入66 kV白大甲线;运用电力系统分析程序包计算这两种方案的潮流分布,从网络损耗、母线电压波动情况以及故障时电力系统的稳定性等方面对这两种方案进行对比分析;最终确定方案二优于方案一。
Design of grid-connection project of Taozi photovoltaic power plant is taken as an example to research on how to choose grid-connection point to photovoltaic power plant.In combination with background information,two schemes for 66 kV access system in Taozi photovoltaic power plant are brought forward： access of 66 kV Yongda line is the first scheme and the access of 66 kV line B of Baida line is the second one.Power flow distribution of the two systems is calculated by PSCAD and the two schemes are comparatively analyzed in respects of network loss,bus voltage fluctuations and power system stability when fault occurs.It is finally determined that scheme 1 outgoes scheme 2.
