| Abstract: | The comparison between physical simulation and digital simulation of HVDC transmission system illuminates that the latter has the advantages in security,economics and convenience.The rapid development of relative technologies,such as digital computer and computational techniques,makes it possible technically.The general principles and requirements for establishing the model of HVDC transmission system based on PSCAD/EMTDC(Electro Magnetic Transient in DC System)are proposed.The DC control and protect system should be reserved in the model,the dynamic performance of the system kept and the AC system simplified according to some principles. |
