| Abstract: | The paper introduced the construction and control principles of large-scale grid-connected PV system and established mathematical models of Photovoltaic cells,inverter and control system.One 50 MW grid-connected PV system model in Inner Mongolia was built upon the RTDS digital simulation device.The system simulation model not only analysed the influence of the intensity of illumination and temperature variation on through-out power of system,but also tested the validity of the simulation model and the availability of the engineering simulation analysis. |
