Yangqu Hydropower Station is an important supporting peak-shaving power supply for China's first ±800 kV "Qingyu DC" ultra-high voltage transmission channel and an important supporting power supply for Hainan Prefecture's multi-million-kilowatt new energy base. After the power station is completed, it will effectively guarantee The "Qingyu DC" UHV transmission channel delivers power at full capacity, providing strong support for promoting the large-scale development and application of new energy in Qinghai Province and building a clean energy base in the upper reaches of the Yellow River.
"The runner is the core component of the hydrogenerator unit that generates electrical energy, and is known as the 'heart' of the hydrogenerator unit. The runner hoisted this time is assembled and welded by the upper crown, lower ring and 15 blades, with a maximum diameter of 6.37 meters, with a height of 3.29 meters and a total hoisting weight of about 114 tons. It took a total of 52 minutes to complete the hoisting." said Yang Yunfeng, director of the Yangqu Preparation Office of Huanghe Company.

It is reported that at present, the Yangqu Hydropower Station dam project, water diversion system, factory building project, spillway and spillway tunnel are in the critical stage of water storage under the sluice. The ecological water discharge tunnel, fish lift system and fish breeding station, tamarisk protection and other ecological As an important part of hydropower station construction, protection projects are being fully promoted.
Yangqu Hydropower Station is located at the junction of Xinghai County and Guinan County in Hainan Tibetan Autonomous Prefecture, Qinghai Province. It is a major project of Qinghai Province and the State Power Investment Corporation. It is a first-class large (Ι) type project. It is the first in China to use inlaid concrete face rockfill dam. It can reduce the amount of excavation of toe plate foundations in narrow valleys and effectively reduce the settlement deformation of face rockfill dams, providing practical experience for the construction of 300-meter-high face rockfill dams in China.
The power station is equipped with three 400,000-kilowatt Francis turbine generator units with a total installed capacity of 1.2 million kilowatts and an average annual power generation of 4.732 billion kilowatt-hours, which is equivalent to saving about 1.66 million tons of standard coal every year.
