A interval algorithm based system analysis method is proposed in the paper for predicting bus voltage sags during unsymmetrical faults in a tolerance transmission network. 摘要基于区间算法提出一种预估容差输电网发生不对称故障时引起母线电压骤降的系统分析方法。
According to the rules, there should be people especially assigned in a power network to save electrical power. 按照规定，电力网应设有专责人员负责节电工作。
Right now, I believe the best option available for the power network is superconducting cable, and government officials are beginning to realise this too. 我认为目前电力网建设的最佳选择是超导电缆，政府官员也开始意识到了这一点。
