基于EMTP/ATP的户用光伏发电系统建模与仿真

摘要

利用户用光伏发电系统开发偏远地区太阳能资源,可以有效解决该地区用电难问题,有必要建立户用光伏发电系统的仿真模型.在电力系统电磁暂态软件EMTP/ATP仿真环境下,建立了随机光照、温度、太阳能电池等仿真模型,同时结合Cuk斩波电路、蓄电池、PWM单向逆变器等,构建了简单的户用光伏发电系统,并对该系统在离网运行模式下的运行特性进行了研究,仿真结果验证了模型的有效性.%As electricity shortage can be effectively alleviated by developing the household photovoltaic power system in vast rural areas,it is necessary to establish the simulation models of the system.By using EMTP/ATP simulation tools,the models of household photovoltaic power system including stochastic illumination,temperature and photovoltaic alleys are properly bui at the same time,combined with the Cuk-chopper circuit,batteries and the single phase PWM inverter,a simple household PV generation system is set up and the operation characteristics of the system under the off-grid mode is studied.The simulation results have proved the validity of the model.
