摘要

以研究2010年南方电网动态特性为目的，提出了含±800 kV特高压直流的多馈入交直流系统动态特性仿真研究重点，解决了大规模多馈入交直流系统电磁暂态仿真时系统等值、模型处理以及仿真步骤等问题。依此运用PSCAD/EMTDC电磁暂态仿真软件，建立了包含±800 kV云广特高压直流等5条直流输电线路的电磁暂态仿真模型，研究中换流器模型采用详细模型。在此基础上研究了交直流系统各种故障下的动态特性，研究结果为南方电网规划及安全稳定措施的制定提供了理论依据。提出建立电磁暂态仿真模型，为研究大规模含特高压直流的多馈入交直流系统的动态特性提供了一套可行的方法。

Abstract

To study the dynamic performance of the Southern China Power Grid in 2010， the system equivalence， model treatment， electromagnetic transient modeling method are presented for the multi-infeed AC/DC power system including±800 kV UHVDC. The PSCAD/EMTDC electromagnetic transient simulation software is used to establish the simulation model of 5 HVDC transmission lines， including±800 kV UHVDC from Yunnan to Guangdong. Detailed converter model is used in the study. The work has focused on the dynamic performance when various kinds of faults occur in the AC/DC system. Result presented in the paper provides the theoretical foundation for system planning and system security study in the Southern China Power Grid.
