摘　　要：对直流输电系统物理仿真和数字仿真进行了比较 ,说明了直流输电系统数字仿真具有安全性、经济性和方便性等优点 ,且数字计算机、数值计算技术以及与系统仿真有密切关系的新技术的飞速发展为其提供了技术可能性 ,提出了基于PSCAD/EMTDC软件建立直流输电系统模型应该遵循的一般原则和要求 :在模型中保留直流控制保护系统、保持系统的动态性能和对交流系统进行有原则的等值简化。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.
