光伏—储能混合系统接入配电线路雷击过电压分析
Lightning Overvoltage Analysis of Photovoltaic-energy Storage Hybrid System Connected to Distribution Line
摘要
Abstract
Lightning is the main cause of faults in active distribution lines.It is of great significance to analyze the lightning overvoltage of active distribution network for lightning protection.In this paper,the distribution network with distributed photovoltaic and energy storage system(PV-ESS)was taken as the research object.The calculation model of lightning overvoltage for the distribution lines with distributed photovoltaic and energy storage system was set up,and the overvoltage distribution of active distribution lines under different topologies was analyzed respec-tively.In addition,the influence of lightning overvoltage on the energy storage device was analyzed by changing the energy storage system configuration in the active power distribution system.The results show that compared with the chain and star topological structures,the active distribution line under the ring topologica structure is less affected by lightning overvoltage,and the protection measures at the inverter should be strengthened.When the energy stor-age device is added to the system,the influence of lightning overvoltage can be reduced.关键词
