摘　　要：全控型电力电子器件电压源型换流器VSC(Voltage Source Converter)的出现,为直流输电发展提供了新方向。在分析多端VSC-HVDC稳态模型基础上,导出了其适用于牛顿法潮流计算数学模型。提出了一种应用统一迭代法对含有VSC交直流混合系统进行计算的方法。通过修改IEEE-14节点系统仿真结果验证了该算法的有效性和准确性。The emergence of full-controlled power electronic devices, such as VSC, provides a new direction for the development of HVDC. Based on the analysis of the steady-model of VSC-HVDC, its mathematical model for Newton method power flow caluclation is developed. This paper proposes a uniform iterative power flow calculation algorithm for systems equipped with VSC-HVDCs. Simula- tive results for the modified IEEE-14 demonstrate its validity and accuracy.
