Recently, at the foreign ministry's regular press conference, Foreign Ministry spokesman Zhao Lijian asked a question: Where does the "green electricity" used in the Venues of the Beijing Winter Olympics come from?
The Zhangbei Renewable Energy Flexible DC Power Grid Experimental Demonstration Project (hereinafter referred to as the "Zhangbei Soft Direct Project"), the Fengning Pumped Storage Power Station, the Olympic Welcome Photovoltaic Corridor Project and other projects participated in by China Energy Construction will "package" renewable energy such as wind power and photovoltaics in Zhangjiakou and other areas to Beijing, helping the Winter Olympic venues to be 100% all-green for the first time in the history of the Winter Olympic venues.
We used the wind of Zhangbei to light up the lights in Beijing and make the Winter Olympics very "beautiful"!
A wind in Zhangbei blows from spring to winter; the sun is strong and fierce, that is, unstable. Zhang Bei's soft straight project, with a large net in the shape of a "mouth", tamed the disobedient scenery "green child".
▲Fengning pumped storage power station
It is the world's first flexible DC power grid project that transmits large-scale wind power, photovoltaic and pumped storage energy in various forms of energy, and the core technology and key equipment are the first in mainland China.
▲Zhangbei Rouzhi - Yanqing Converter Station
China Energy Construction experts and Tsinghua University jointly developed the world's first 535 kV coupled negative pressure hybrid DC circuit breaker to ensure that the power grid is stable and not the overall "trip", solve the "card neck" technical problem, and deliver about 14.1 billion kWh of clean energy to Beijing every year, which is about 1/10 of Beijing's electricity consumption, reduce carbon dioxide emissions by 12.8 million tons, and help Beijing Winter Olympics achieve 100% green electricity.
▲The Zhangbei Rouzhi Project spans the Guanting Reservoir
China can build the world's largest "charging treasure" Fengning pumped storage power station, with a total installed capacity of 3.6 million kilowatts, connecting the new energy energy stored by the Zhangbei Rouzhi Project with excess or random fluctuations, and releasing it when necessary to ensure that the power grid delivers stable and clean electricity to the Winter Olympics.
▲Welcome photovoltaic corridor
Olympic welcome photovoltaic corridor project, to create a world-class ecological landscape channel, strength and appearance, we let the Olympic "scenery and scenery".
