杭州东站10 MWp并网BIPV项目计算及校验

摘要

The grid-connected BIPV system is adopted for 10 MWp PV power generation demonstration project in Hangzhou East Railway Station to integrate the grid-connected PV power generation and the rail transportation buildings. In the paper, the calculation& verification and key issues in the design are discussed, including the estimate of generating capacity of PV power generation system, calculation of DC line voltage drop and system short circuit current, selection of cable cross-section and relay protection setting.%杭州东站10 MWp光伏发电示范项目采用并网BIPV系统，实现光伏并网发电和轨道交通建筑房屋一体化。对其设计中若干计算校验及重点问题进行讨论，包括光伏发电系统发电量估算、直流线路压降计算及电缆截面选择、系统短路电流计算及继电保护整定等。
