Ningxia's first "13th Five-Year" photovoltaic poverty alleviation village-level power station
On June 25, 2019, the PV poverty alleviation village-level power station in Baoyang Village, Pengyang County was successfully connected to the grid, marking the successful integration of the full capacity of 89 power stations in the 26.68MWp PV poverty alleviation village-level project in Pengyang County. The first full-capacity grid-connected county among the first batch of photovoltaic poverty alleviation village-level power stations.
Based on its years of experience in intelligent monitoring and protection in the electric power industry, Beijing Huafu Juneng has been focusing on user-centric products and deepening product innovation. The model of the distributed poverty alleviation photovoltaic grid-connected solution for this project is HF-BSP photovoltaic grid-connected access box. The supporting model is HF-2000 distributed photovoltaic grid-connected interface devices, a total of 89 sets, adopting 4G wireless transmission mode, and the data of Huawei inverters and pole transformers of the distributed photovoltaic area are respectively connected to the Guyuan City dispatching system and The Big Data Center of the Poverty Alleviation Office has fulfilled the requirements for automation and intelligent operation and management of the entire power station.
