摘要: 本文建立了两条交、直流并联的多馈入高压直流输电系统模型，基于电路基本理论知识，推导出与多馈入交、直流并联的交流传输线导纳和换相电压关系表达式。并对此模型的交流传输线导纳和换相失败关系进行了详细的理论分析研究。从本文的理论分析可看出逆变侧换相失败与传输线导纳关系十分复杂，它不仅与各直流输电子系统逆变侧相连的交流电源的等值导纳有关，而且还与各直流输电子系统整流侧相连的交流电源的等值导纳有关。
Abstract: In this paper, two AC/DC parallel multi infeed HVDC transmission system models are established. Based on the basic knowledge of circuit theory, the expressions of admittance and commutation voltage of AC transmission line with multi infeed and DC parallel connection are derived. In addi-tion, the relationship between the admittance and the commutation failure of the AC transmission line is studied in detail. From the theoretical analysis that the inverter commutation failure admittance and transmission line relations are very complex, it is not only the equivalent admittance of AC power supply and DC transmission electronic system connected to the inverter side AC power supply, but also with the electronic rectifier DC transmission system connected to the value of admittance.
