摘要
结合项目实例,介绍某商业建筑屋面分布式光伏发电系统电气设计内容,从光伏相关主要设备选择、光伏阵列设计,到如何实现0.4 kV低压并网接入原有配电系统,并结合现场实际完善系统的防雷接地,最后通过修正综合效率系数,估算发电量。
Based on project case,the content of electrical design of roof distributed generation photovoltaic system for a commercial building is introduced,including the selection of PV⁃related main equipment,the design of PV array,and the connection of 0.4 kV low⁃voltage grid to existing distribution system.Meanwhile,lightning protection and grounding for the system are improved according to the actual situation on site.Finally,the overall efficiency coefficient is corrected to estimate the electric energy production.
