Information

The beautiful Daocheng Yading Scenic Area is located in Yading Village, Shangri-La Town, Daocheng County, Ganzi Tibetan Autonomous Prefecture, Sichuan Province. It is mainly composed of three sacred mountains "Xiannairi, Yangmaiyong, Xianuoduoji" and surrounding rivers, lakes and alpine meadows. , Its scenery maintains the purity that is nearly extinct on the earth. Because of its unique topography and original natural scenery, it is known as the "soul of Shangri-La in China", and it is praised by international friends as "the last piece on the water blue planet". "Pure Land" is a paradise for photography lovers.

Due to the influence of the plateau climate, in the Yading Nature Reserve, there are still some barren hills with sparse vegetation and increasingly serious water and soil desertification. In order to preserve this last piece of original ecological pure land and cope with the impact of the harsh natural environment, the Sichuan Provincial Government has been planning to control soil erosion and desertification of barren mountains in 2014, and the Sichuan Provincial Department of Agriculture has set aside special funds for use. In the vegetation restoration work in the Daocheng Yading Nature Reserve, cold-resistant tree seedlings were provided free of charge, and the original vegetation was restored by means of artificial afforestation and photovoltaic solar water pumping to prevent further deterioration of soil erosion. Therefore, Guangzhou Sanjing Electric Co., Ltd.'s latest solar photovoltaic pumping control program comes in handy.

The system is designed to install 160KW components, 400m head, and 100m³/h flow rate. Three sets of 75KW (considering the influence of high altitude) Sanjing Electric's new generation PDS23 series photovoltaic pumping inverters are used to control four sets of 37KW pumps (three uses and one standby). Three photovoltaic pumping inverters are multi-connected control, according to the high-precision MPPT tracking module output power, the output frequency is automatically adjusted with the size of the sun, the pump is added or subtracted, and the efficiency of solar energy is maximized, even in a completely cloudy and rainy day. Pumping water has the effect of water when there is light. Every day from the moment the sun appears in the morning until the sun goes down in the evening, the pump continues to work. PDS23 series inverters are also compatible with upper and lower water level control, power-on self-starting, water shortage, over-current, over-voltage and other protection functions, truly realizing 24-hour unattended, automatic control operation.

The photovoltaic water pumping system of Daocheng Yading Nature Reserve is not only the largest photovoltaic water pumping system built in China, but also the most efficient and automated photovoltaic water pumping system currently built in China. With its MPPT tracking efficiency of up to 99% and multi-line automatic processing Reduce the pump, automatically adjust the speed of the water pump, use solar energy as a clean energy to the maximum efficiency, and win high praise from customers. As a large-scale forestry greening photovoltaic demonstration project in Sichuan Province, this system adds a new touch to the Yading Nature Reserve without causing any pollution to the nature reserve.
