Changzhou Hydropower project uses more than 40 sets of DC intelligent PDU K4 series of our Qunfang technology.
Changzhou Hydropower Station is the largest pumped storage power station in Jiangsu Province at present. It is invested by Jiangsu Guoxin group with 8.9 billion yuan. It is a key project in the 12th Five Year Plan of Jiangsu Province. It took nine years to complete. A total of 6 250MW vertical shaft single-stage reversible mixed flow pumped storage units are installed, with the designed annual power generation of 2.007 billion kWh and the annual pumped power of 2.676 billion kwh. Changzhou Hydropower Station is the most difficult hydropower project in China due to its extremely complex geological conditions. During the construction process, 14 utility model patents and 4 provincial and ministerial scientific and technological achievements awards were created. Six units will be put into operation within one year, which is the first case in China. This project uses DC intelligent PDU K4 series produced by our Qunfang technology, with stable performance and good feedback
