基于EMTP/ATP的户用光伏发电系统建模与仿真

Modeling and Simulation of Household Photovoltaic Power System Based on EMTP/ATP

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 photovohaic 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 photovoltaie power system including stochastic illumination, temperature and photovoltaic alleys are properly built; 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.
