Beijing Winter Olympics will achieve 100% clean energy power supply

Original source: Science and Technology Daily

With the "tick" sound of the countdown to the Winter Olympics, various "Olympic-related" projects for the 24th Winter Olympic Games are being pushed forward intensively and efficiently.

So, how to realize the supply of "all green electricity" and help carbon neutrality? A reporter from Science and Technology Daily came to the Bashang area, which is 270 kilometers away from Beijing, the Zhangbei Renewable Energy Flexible DC Grid Test Demonstration Project (hereinafter referred to as the Zhangbei Rouzhi Project) to explore the secrets behind it.

Zhangbei's "Scenery" lights up the Winter Olympics venues

"Close, execute!" With the operator's order, the knife switch and the 4 DC circuit breakers in the valve hall of Zhangbei Converter Station were successfully closed, and the photovoltaic power curve on the monitoring screen of the main control room began to gradually rise—— The Zhangbei Rouzhi Project was officially put into operation.

Zhangbei is rich in wind power and solar power resources, known as the "hometown of wind, ocean of light", and has excellent development conditions, with a scale of up to 85 million kilowatts.

“The Zhangbei Rouzhi Project has significantly improved the local new energy delivery capacity.

The reporter learned that after the project started in February 2018, the builders overcame difficulties, ensured the construction quality and progress, and completed the construction task in December 2019.

Focus on green Olympics and create a clean and low-carbon Olympic zone.

　　Details make the world's leading original technology

　　Zhangjiakou area is an important new energy base in my country.

　　According to reports, the Zhangbei Flexible Direct Project adopts my country’s original and world-leading new flexible DC grid technology.

　　“Converting AC power to DC power is one of the ways to effectively deliver power from the source to the client.

　　Just like "God Operation", the company's converter station can convert the energy of wind turbines into direct current.

　　The “behind the scenes” of ensuring the normal operation of the converter station is the solution provided by the pump manufacturer Grundfos.

　　It is precisely with many such excellent details that the Zhangbei flexible DC project has achieved 12 world firsts, effectively solving the three major problems of "not available", "unsending" and "difficult to absorb" green power in Zhangbei area.

　　It is particularly worth mentioning that after the project is put into operation, it can meet the demand for delivery and consumption of 7 million kilowatts of new energy installed capacity, fully meet the electricity demand of 26 Winter Olympic venues in Beijing and Zhangjiakou, and save 490 standard coal every year.
