PRLog (Press Release) - Dec. 26, 2013 - On 25th December 2013 the Chinese national project of a three terminal flexible HVDC for Southern Power Grid (CSG) was placed into operation. This benchmark project is siutated on Nan’ao Island in Shantou city in the Guangdong province of China. This event is significant in the industry as RXPE has overcome the intricacies of the control and protection technologies of multi-terminal flexible HVDC which was the industries toughest problem to solve. China now becomes the first country that fully master the whole series of core technologies (design, test, commission and operation) for the HVDC industry.

Rongxin Power Electronic Co. Ltd (RXPE) assumed the research and development, design and manufacturing tasks for main converter valve, control & protection system. The success of this project means that RXPE leads in the world in the field of flexible HVDC technology.

Flexible HVDC technology is one of the most advanced electric power technologies. It has been brought to the attention of the world's major developed countries. There are limited public related technical papers and materials on this subject. Multi-terminal flexible HVDC is more complex than point to point or two terminals’ HVDC.

The Nan’ao multi-terminal flexible HVDC project, has a designed capacity of 200MW and the DC voltage level is ±160kV. It is the world's first flexible multi-terminal HVDC project.

It has major technological significance in the history of HVDC transmission and sets the foundation and new standards for TSO and DSO in the world.

This project will provide a safe and efficient solution for long-distance large-capacity DC transmission, large scale clean intermittent power supply, multi DC in-feed and power supply for isolated offshore systems or to remote areas.

This latest development is a milestone in the progress of international HVDC technology and highlights RXPE’s capabilities as an international entrant and leader in advanced power electronic solutions.

RXPE’s previous world records include

STATCOM - In early 2011, Rongxin Power Electronic Co, Ltd commissioned the world largest STATCOM rated at a robust ±320 Mvar, setting a world record for the largest Dynamic Reactive Compensation STATCOM and due to its success in service the company subsequently installed a further three in the critical HVDC network.
