仅给出摘要表格。本文介绍了一种稳态多端电压源换流器高压直流（VSC MTDC）模型。所提出的方法扩展到包括具有任意拓扑的多个交流和直流电网。因此，直流电网可以互连一个或多个非同步交流系统中的任意总线。转换器方程以其最通用的格式导出，并正确定义相对于系统总线而不是转换器或滤波器总线的所有设定点，这通常是为了简化计算。本文介绍了一个包含转换器限制的数学模型，并讨论了当考虑无变压器操作或省略转换器滤波器时方程如何变化。使用 MATPOWER 实现了 AC/VSC MTDC 潮流，以显示广义潮流模型的有效性。
Summary form only given. In this paper, a steady-state multi-terminal voltage source converter high voltage direct current (VSC MTDC) model is introduced. The proposed approach is extended to include multiple AC and DC grids with arbitrary topologies. The DC grids can thereby interconnect arbitrary buses in one or more non-synchronized AC systems. The converter equations are derived in their most general format and correctly define all set-points with respect to the system bus instead of the converter or filter bus, which is often done to simplify calculations. The paper introduces a mathematical model to include the converter limits and discusses how the equations change when a transformerless operation is considered or when the converter filter is omitted. An AC/VSC MTDC power flow is implemented using MATPOWER to show the validity of the generalized power flow model.
