基于CIGRE直流工作组的多馈入直流短路比（MISCR）的定义，引入直流权重因子，建立了分层接入方式下直流落点的稳定性指标，并结合经济性指标，构造线性权重的目标函数进行落点优化。算例分析表明本研究方法切实可行，便于工程应用。

There are limited studies on the selection of DC links termination in ultra high voltage DC (UHVDC)hierarchical connection mode due to the speciality of the mode.Based on the definition of multi-infeed short circuit ratio,the index to screen terminal location schemes under the hierarchi-cal connection mode was established combined with the DC weight factors.The objective function of the DC links selection based on the linear weighted summation method was formulated to select the optimal scheme as the commutation bus.Numerical tests show that the method is effective,feasible and convenient for engineering applications.
