摘要
多馈入短路比是研究多馈入直流系统的重要参考指标,以往的研究大多仅考虑送端或仅考虑受端,对于整流站与逆变站临近的多直流系统,传统的多馈入短路比已无法正确描述其运行特性.本文在原有研究基础上,通过理论分析深入研究了整流站与逆变站临近的多直流落点系统短路比以及电气距离对它的影响,给出了整流站与逆变站临近的多直流落点系统短路比的变化规律.基于CIGRE模型建立了两条整流站与逆变站临近的直流输电模型,通过仿真分析验证了其有效性.
Abstract
Multi-infeed short circuit ratio (MSCR) is an important reference index in the study of multi-infeed HVDC power system,however,previous studies only consider the sending end or receiving end.For multi-HVDC system of rectifier station near the inverter station,the traditional MSCR has been unable to correctly describe its running characteristics.Based on the original research,this paper studies the MSCR of multi-HVDC system of rectifier station near the inverter station,analyzes the influence of electrical distance,and generalizes the variation rule of its MSCR.Finally,based on CIGRE model,a 2-different end DC power transmission model is built.The simulation analysis has verified its validity.
