摘要

多馈入高压直流输电系统（line commutated converter based high voltage direct current

LCC-HVDC）的新增直流落点选择问题需要考虑多回直流间的交互作用影响。为兼顾电网稳定性与经济性

本文建立包括多馈入短路比（multi infeed short circuit ratio

MISCR）、直流换相失败风险以及系统抵御N-1故障所需的动态无功补偿容量的指标体系。在此基础上

采用归一化处理和线性加权法实现落点方案的比选。最后

结合乌东德直流工程

将本文提出的直流落点优选方案应用于实际算例。

Abstract

The selection of new addition of DC system for multi infeed LCC-HVDC transmission system needs to consider the interaction between multiple direct currents. For the consideration of both grid stability and economy

in this paper

the needed index system of dynamic reactive power compensation capacity including MISCR（multi-infeed short circuit ratio）

DC commutation failure risk and resistance of N-1 fault by the system is set up. On this basis

the comparison and selection of the HVDC system proposal is achieved by the use of normalization treatment and linear weighting. Finally

the optimization scheme proposed in this paper is used in actual example of Wudongde HVDC project.
