From the initial operating point, this method searched the new instability modes with the change of parameters by the way of iteration.

该方法从初始运行点出发，通过迭代确定系统失稳模式随参数变化的情况。

Then using the approximate solution as initial value of iteration, the nonlinear equations for the closest point of collapse are solved directly by Newton-Raphson method.

然后采用牛顿-拉夫逊法直接对最近电压崩溃临界点模型所构成的非线性方程组进行迭代求解。
