Rongxin Huiko Electric (RXHK) has won a contract to supply a set of converter valves for the onshore converter station of the Rudong offshore wind demonstration project in China.
RXHK will supply ±400kV 1,100MW VSC HVDC converter valves for the station, including all insulators and AC-DC hardware fittings, together with the valve cooling and auxiliary system, control system, access platform for maintenance, spare parts and special tools.
The equipment is scheduled to be delivered to the site by September 2020.
The Rudong offshore wind farm HVDC demonstration project is located in the southeast of Jiangsu Province on the northern edge of the Yangtze River Delta.
The project, with a total installed capacity of 1,100MW, comprises three wind farms, which are owned by China General Nuclear Power Corp (CGN) Nantong Ltd and China Three Gorges (CTG) New Energy Corp Nantong and Rudong Ltd.
Electric power generated by the wind farms is transmitted to three separate offshore AC substations via 35kV cable and transformed to 220kV before it is further transmitted to the offshore converter station.
The power is converted to DC and then transmitted to an onshore converter station via a single, two core ±400kV cable. After being converted to 500kV AC in the onshore converter station, the power flows into the China State Grid Jiangsu power network.
