Commutation failure factors analysis in hvdc transmission system
直流输电系统中逆变器换相失败的因素分析
I . e . strong coupling critical admittance and weak coupling critical admittance that affect the occurring conditions and types of commutation failures in multi - infeed hvdc system , are defined in this paper . factors which has great influence on the above two parameters , such as ac system strength
针对一个典型的多馈入直流输电系统，首次定义了影响多馈入直流输电系统中换相失败及其发生类型的两个重要参数，即强耦合临界导纳和弱耦合临界导纳。
