Abstract: In order to solve the problems of large occupied land area, long construction period and high cost of traditional construction photovoltaic power station, a set of 1MW box-type photovoltaic grid connected integrated power station has been developed. Introduction was made to its working principle and integrated design flow. This box-type substation adopted the heat-dissipating methods of "one" type arrangement and air conditioning with cooling fans , so that it had high power density with good operating environment. According to the required functions such as confluence, inverter, boosting and grid connected, this paper designed each module of main circuit and carried out the model selection. After the field experimentation, the system design scheme is verified, which realizes the intensive and standard construction of photovoltaic power station.
Key words: photovoltaic power generation; box-type substation; inverter; standardization
