提出了多端电压源换流器（VSC）型高压直流输电（HVDC）的两种数学模型。第一种模型假设所有换流器都位于同一变电站，而第二种模型是通用模型，其中直流网络可以显式表示。对于这两种模型，初级换流器基本上有能力独立地控制有功和无功功率或有功功率和电压的终端，而多端VSC HVDC的次级换流器可以用来控制终端总线电压和平衡VSC换流器之间的功率交换。此外，还对多端VSC HVDC与VSC FACTS控制器--广义统一潮流控制器进行了理论和数值比较。给出了IEEE 30节点系统、IEEE 118节点系统和IEEE 300节点系统的算例。
Two mathematical models for multiterminal voltage-sourced converter (VSC)-based HVDC are proposed in this paper. The first model assumes that all the converters are co-located in the same substation while the second model is a general one, in which DC network can be explicitly represented. For both models proposed, primary converters basically have the ability to independently control either active and reactive power or active power and voltage of the terminals while the secondary converter of the multiterminal VSC HVDC can be used to control terminal bus voltage and balance power exchange among the VSC converters. In addition, theoretic and numerical comparisons between the multiterminal VSC HVDC and the VSC FACTS controller-the Generalized Unified Power Flow Controller are also presented. Numerical examples are given on the IEEE 30-bus system, IEEE 118-bus system and IEEE 300-bus system.
