New generation digital HVDC simulation module of SCDTS

The article introduces the digital HVDC simulation module of South China Dispatcher Training System (SCDTS). South China power system has built Tian-Guang HVDC transmission system which was put into operation in two stages. Therefore the digital HVDC simulation module has experienced two stages. The article introduces the characteristics of the former and new generation of HVDC simulation module implementation method of the new generation and real-time T-G HVDC operating standards. Finally, it presents simulation examples of Tian-Guang HVDC operation and draws conclusions.
