Recently, the 23rd China Power Supply Society Conference (CPSSC2019) was held in Shenzhen.  The ceremony for awarding the "5th China Power Supply Society Science and Technology Awards" was held at the opening ceremony of the Conference. The "Research and Application of Key Technologies for HVDC Supply System" of Kehua Hengsheng Co., Ltd. won the First Prize for Science and Technology Progress Award.

Approved by Ministry of Science and Technology, China Power Supply Society Science and Technology Awards are expected to be highly respected science and technology awards with recipients nationwide. The goal of the awards is to recognize and reward individual researchers or institutions that make outstanding achievements in scientific research, technical innovation, new products developing and popularization and application of scientific and technological achievements in power supply field, etc. 

The "HVDC power supply system" that won the award

-employs CAN communication architecture with software anti-jamming technology for low conflict data flow control and hardware anti-jamming technology that adapts to multiple BUS architectures so as to realize highly reliable parallel operation for large-scale power supply system;

-employs the energy-saving technology with intelligent sleeping algorithm to realize economical and reliable operation of HVDC system;

-employs the power factor correction technology with adaptive algorithm to reach excellent indexes and realize high adaptability on the power grid side in case of large-scale parallel connection, the full-load THDI is less than 3% and the half-load THDI is less than 5%..

At present, Kehua HVDC power supply system project results have been put into "scale production" and successfully applied in such large datacenter projects as Shanghai Bao Cloud Datacenter, ICBC Datacenter (Shanghai), China Mobile Nanjing Jiangbei Datacenter and China Telecom Guangzhou Keyun Datacenter.
