This method can utilize the minimum control charge to reduce the currents of the primary power flow off-limit branches to the object boundary.
该方法可用最小的控制代价，使原越限支路电流降至目标电流范围。

Admittance parameters of the virtual branch can be obtained by object shunting coefficient, Thevenin's equivalent resistance and the admittance of the primary branch of power flow off-limit.
虚拟支路的导纳参数可由目标分流系数、戴维南等效阻抗及原潮流越限支路导纳获得。

But workers are wearing protective clothing, working in brief shifts and being occasionally pulled off the site to limit accumulated exposure.
