摘　　要：介绍了直流输电线路离子流场计算中主要的3种方法:半经验公式法、基于Deutsch假设的数值计算方法和二维数值计算方法。简要介绍了每种方法的原理、实现过程和优缺点,比较了3种方法在准确度、计算效率和实现难度上的差别。文章认为,为满足我国不断发展的电网建设要求,以不断进步的计算机硬件和数值计算方法作为保障,二维数值计算方法将是研究的重点。This work summarized three main methods of ion flow field calculation of HVDC transmission lines, which are semiempirical method, Deutseh assumption based numerical method and 2-D numerical method. The principles, implementations and characteristics of the methods are briefly introduced. The differences on accuracy, efficiency and difficulty of three methods are compared. As the development of power system in China, with the supports of advancing computer hardware and numerical computation methods, the 2-D numerical methods should be the focus.
