| 摘 要： | 首先阐述了进行高压直流输电系统主回路参数计算时所必需的系统基本状况和系统数据，然后分析讨论了换流变压器的短路阻抗和有载调压抽头调节范围的选取思路。根据目前实际高压直流输电工程中所采用的不同控制策略，分别论述了相应的主回路参数计算方法，并开发了自主知识产权的主回路参数计算软件;最后，以3个实际的高压直流输电工程为例，相对于Siemens公司和ABB公司相关软件的计算结果，进行了自主开发软件计算功能正确性的测试。测试结果表明，所开发的软件计算功能正确，可以用于今后高压直流输电工程的成套设计中。

| Abstract: | Firstly in the paper,system basic conditions and data required for calculating main circuit parameters of high voltage direct current(HVDC)transmission systems are described.Secondly,the idea of selecting the short circuit impedance and on-load tap changer range for converter transformer is discussed in detail.For the different control strategies adopted in actual HVDC transmission projects,the corresponding computational methods of main circuit parameters are discussed.Computational software with autonomous intellectual property for the main circuit parameters has been developed.Finally,the tests are performed on three practical HVDC transmission projects.Compared with the results from using Siemens' and ABB's software,the functions of the software developed are validated to be correct.It is proposed to be used in the practical design of HVDC transmission in future. |
