摘要
系统分析了多馈入直流对受端交流系统的影响,指明多馈入短路比(M ISCR)可以作为表征交直流混合系统运行性能的综合指标。综合分析国内外对于多回直流馈入系统(M IDC)影响研究现状,将多馈入直流对受端电网的影响分为直流线路对弱交流系统的影响和多回直流交互作用产生的影响两大类,并提出改善措施。
It analyzes the impact of multi-infeed DC on receiving end AC system,indicating that multi-infeed short-circuit ratio can be a token representing a comprehensive index for operating performance of a mixed system-AC and DC.Overall analysis on current status both home and abroad of multi-infeed DC system is made,which is classified into two categories,one is DC transmission line impact on weak AC system,and another is impact of interaction among multi-infeed DC systems.
