China Three Gorges Corporation’s Yangjiang Qingzhou Phase 5, 6 and 7 Offshore Wind Power Project boasts a total installed capacity of 3 gigawatts, claiming six world records including the world’s offshore wind project with the largest power transmission capacity and the world’s offshore wind flexible DC transmission project of the highest voltage level. The supporting offshore converter stations for Qingzhou Phase 5 and 7, hailed as the “Heart of Offshore Wind”, rank as the world’s largest offshore converter stations, which were officially shipped on May 27, 2026. Against the harsh operating conditions of offshore converter stations featuring high equipment density, concentrated heat generation, as well as high salt fog and severe corrosion in marine environments, Huadong Power supplied customized standby diesel generator sets with high protection ratings for the project. Equipped with Cummins marine diesel engines and Leroy-Somer marine alternators, these units ensure stable operation of precision electrical equipment onboard and safeguard the safety of power production. Having participated in the project throughout the full lifecycle spanning design, fabrication, delivery and after-sales maintenance, Huadong Power has fully integrated into the entire industrial chain of China’s offshore wind flexible DC technology, aligning with national and global strategies for the large-scale development of deep-sea wind power.

In December 2025, Huadong Power successively delivered 32 pcs 200kw ultra-low temperature diesel generator sets to the Xinjiang Tacheng Wind Power Project of Envision Group. To adapt to the extremely low temperatures in Xinjiang during winter, Huadong Power and Yundian Technology jointly developed and customized this batch of ultra-low temperature diesel generator sets. Different from conventional diesel generator sets, all components of this batch of diesel generator sets are configured according to the extremely cold weather of minus 40 degrees Celsius, such as specially customized Eaton Hiven zero-degree circuit breakers and Huadong Power’s dedicated zero-degree engine oil, etc., to ensure that the generator sets can start and work normally in the extremely cold weather of minus 40 degrees Celsius. The core diesel engine is the Shangchai 6DTAA8.9-G33, the generator is the DG274L anti-condensation motor, the cooling system uses BASF G30 coolant, with a freezing point as low as minus 45 degrees Celsius. The generator set has an integrated silent outer box, with an anti-corrosion grade reaching C4WH, and is also equipped with an automatic fire protection system, lightning rods and solar panels for battery charging, to maximize the safety performance and service life of the generator set.
