SGCC takes important step toward super grids
DNV KEMA has witnessed and confirmed the successful testing of C-EPRI Electric Power Engineering's (C-EPRI) self-developed prototype ±320kV/1000MW, 1563A IGBT valves based on the IEC 62501 standard. C-EPRI is a company wholly owned by Smart Grid Research Institute (SGRI), a subsidiary of State Grid Corporation of China (SGCC).
The testing and certification marks an important milestone in HVDC transmission technology and the next step in the development of super grids.
The type tests were performed at the Power Electronic Lab of SGRI, and included both operational and dielectric tests. The prototype passed all tests required by IEC 62501, making C-EPRI the first power electronics manufacturer with successfully type tested 320kV, 1563A IGBT valves.
"The witness type test demonstrates another example of successful collaboration between DNV KEMA and C-EPRI since the first Ningdong-Shangdong ±660kV 4000MW LCC HVDC project in China in 2008," Dr. Yanny Fu, DNV KEMA, said in a statement. "C-EPRI provides an effective solution for wind integration, in particular for large offshore wind farms with transmission distance of more than 50-100 km where an AC cable technology is not feasible."
