Therefore, the short-circuitcapacity of the power network must be decided in the middle way between the running quality and the breaking capacity of the switches.
因此，电网短路容量水平必须在运行质量和开关开断能力间折中决策。

Two Solutions to the model equivalent parameter estimation are proposed, one based on the three-phase short-circuitcapacity, this method works with good computational speed, but accuracy is not high;
对该模型提出两种求解方法，一是基于三相短路容量思想的等值参数估计，计算速度快，但精度不高；
3
In this case the shortcircuit level is way above the existing interruptive capacity.
