户用光伏发电系统设计与研究

针对目前我国新农村建设过程中的实际情况,为使太阳能这一新能源更好的服务于农村电气化建设,以沈阳农村地区为例,根据当地的气象、环境状况及具体负荷情况,进行户用独立光伏发电系统设计,对系统的光伏倾角、光伏电池板、蓄电池、控制器及逆变器等进行了优化的设计与选择,在满足用户供电需求下,尽量减少初始投资,同时归纳了设计过程中应注意的事项。用专业的光伏系统设计软件PVSYST对设计方案进行仿真,对其用户满足率、能量利用率、蓄电池工作状态、经济效益及环境效益进行了详细的分析,验证了设计方案的可行性。

Design and Research on Household Photovoltaic Power Generation System

Aiming at the actual situation of the new rural construction of our country,the stand-alone PV power system taking Shenyang rural areas as an example was designed according to the local weather and environment conditions and specific load conditions in order to make solar energy better serve the rural electrification construction.Under the condition of satisfying the user demand on photovoltaic power supply,dip Angle,photovoltaic panels,storage battery,controller and inverter were designed and chosen optimally to reduce the initial investment,and the matters needing attention were summarized.The author used the professional photovoltaic system design software PVSYST to simulate the design scheme,detailed analyzed the user meet rate,energy utilization rate,storage battery condition,economic benefits and environmental benefits to verify the feasibility.
