光伏电源并网后,配电网络由单电源放射状的网络变为多电源有源网络,馈电线路有功功率流向发生变化,各个节点电压也将受到影响.对光伏电源并网对系统影响展开全面的讨论,重点研究光伏电源注入位置和注入容量对电压水平的影响,并利用德国电力系统仿真软件Digsilent建立115节点的仿真模型,研究结果表明,在馈电线路上,同一位置光伏电源有功出力越高,电压水平越高,光伏电源接入位置距离母线越远,允许的注入功率值越小.
光伏電源併網後,配電網絡由單電源放射狀的網絡變為多電源有源網絡,饋電線路有功功率流嚮髮生變化,各箇節點電壓也將受到影響.對光伏電源併網對繫統影響展開全麵的討論,重點研究光伏電源註入位置和註入容量對電壓水平的影響,併利用德國電力繫統倣真軟件Digsilent建立115節點的倣真模型,研究結果錶明,在饋電線路上,同一位置光伏電源有功齣力越高,電壓水平越高,光伏電源接入位置距離母線越遠,允許的註入功率值越小.

The distribution network becomes a multi-power active network from a single supply radial network when photovoltaic incorporates into power grid, active power flow of the feed line changes a lot, each node voltage will also be affected. A thorough discussion of the photovoltaic impact on power grid is undertaken, focus on the effect of voltage level injection location and injection capacity of photovoltaic power supply, and the simulation model of the 115 nodes is established by the German power system the simulation software Digsilent, the study results show that, in the feed lines, the same location the number of active output is higher, the voltage is higher ;the distance between photovoltaic and bus bar is futher, the capacity allowed is more smaller.
