Beijing, China, June 1, 2015- The high-power VSC-HVDC dynamic simulation platform developed by SGRI successfully passed the achievement appraisal organized by China Electricity Council (CEC) on May 20^th.

The technical committee all agreed that, “The platform possesses complete intellectual property right, and the comprehensive technical performance has reached international advanced level.”

This novel dynamic simulation platform provides an effective means for the verification of both Valve Base Controller (VBC) and Station Control of a VSC-HVDC system. Prior to its launch, great difficulty was encountered in the test of system performance and reliability due to the complicacy of converter control and for lack of equivalent simulation technology.

SGRI’s initiated the research as early as 2008 with the support of SGCC’s science & technology programs and other national science and technology plans. A series of breakthrough have been made in areas like theoretical equivalent analysis, method study, and technical materialization, etc. SGRI therefore successfully constructed a 401-level MMC-HVDC dynamic simulation platform which includes 6000 submodules. The platform is capable of dynamic simulation for the full-function test of VBC system in 1000MW-level VSC-HVDC projects.

So far, this platform has been utilized for Shanghai Nanhui and Xiamen VSC-HVDC project for system study as well as R&D and test of valve control and station control equipment. The state-of-the-art development has opened new doors for power system dynamic simulation and taken China to a new level in the field of HVDC simulation.

Next, SGRI will work towards the construction of a more ambitious DC grid simulation system and support the development of SGCC’s Strong Smart Grid.
