Baobian Electric has won the bid to provide 13 DC link transformers and associated equipment for the Guangdong Power Grid DC back-to-back Guangzhou project of China Southern Power Grid Corporation (referred to as Greater Bay Area Central Channel DC Back-to-Back Project), with a bid amount of around $67 million. 

The Central Channel project is located in the Development Zone of Zengcheng District, Guangzhou. It utilises 2×1500MW dual-unit back-to-back flexible DC transmission technology to build a back-to-back converter station with a capacity of 3000MVA.

This project includes 13 single-phase two winding oil-immersed water-cooled on-load tapping flexible DC transformers with a capacity of 575MVA (including 1 spare unit), valve-side voltage 300kV and grid-side voltage 525 kV, and 4 sets of water cooling systems. The delivery period is July to October 2021. 

The Central Channel project is the latest DC transformer supply contract won by Baobian Electric after the Yazhong-Nanchang ±800kV UHV DC transmission project, the Qinghai-Henan ±800kV UHV DC transmission project, the Wudongde Power Station evacuation Guangdong-Guangxi UHV multi-end DC demonstration project, and the Zhangbei flexible DC grid test demonstration project.

The transformer for this project is the first domestic water circulation cooling method using variable frequency air-cooled cooling water tower with water cooler. It has the characteristics of low temperature rise and low noise, which is fully independently designed byBaobian Electric and has independent intellectual property rights.
