摘要
逆变器是光伏电站的核心设备,它的选用对投资收益有重要的影响。本文通过对比组串式和集中式逆变器系统在投资成本、发电收益和维修成本上的差异,得出组串式逆变器在大型光伏电站中应用更具有经济可行性的结论。
Inverter is a key device for PV power substations,and the inverter selection has a great impact on investment returns. This paper compares the differences of string inverter and central-inverter system in investment costs,power generating revenue and maintenance costs,and concludes that the string inverter is more economic and feasible than the central inverter when used in large-scale PV power substations.
