A 750-kilovolt (kV) ultra-high voltage substation, the highest of its kind in China, has been put into operation in the country's northwest plateau province of Qinghai.
The substation, which is a part of the CHN Energy Qinghai Maerdang Hydropower Station, is situated in the Hainan Tibetan Autonomous Prefecture at an altitude of 3,365 meters.
Upon completion of 10-month construction, the new substation has raised the voltage grade of the power transmission network in the Golog Tibetan Autonomous Prefecture of Qinghai from 330 kV to 750 kV.
It can transmit about 15 billion kilowatt hours (kWh) of clean electricity every year, facilitating the use of water resources and clean energy development in the upper reaches of the Yellow River, according to Gu Faming, deputy head of the mechanical and electrical center of the CHN Energy Qinghai Maerdang Hydropower Station.
The substation is the first intelligent substation to be equipped with a counter-unmanned aircraft system in Qinghai, which is capable of capturing signals of intruding unmanned aircraft and turning on defense mode to intercept unidentified drones.
It is also an intelligent substation capable of data sharing and intelligent interaction with adjacent substations and power grid control centers, among an array of smart functions.
