摘要
利用一种常用的简化HVDC输电系统模型,基于基频的系统变量分析了直流系统功率传送达到极限的条件.换流器整流侧定电流控制方式下直流功率传送极限和电压稳定性之间的关系已经有明确结论.区分换流器定电流和定功率控制方式,采用经典电压稳定分析判据讨论该模型下换流节点电压稳定性,分析了在两种控制方式下直流传送功率极限和换流节点电压稳定性之间的关系,并结合实例得出了明确的结果.
This paper analyzes the condition in which HVDC system reaches the limit of power transmission with fundamental frequency quantities. Since the relationship between this condition and voltage stability of converter under constant current control mode has been identified, this relationship in both constant current and constant power control modes is elaborated through example.
