Aimed at the problem of choosing the initial value when the Newton method is used to compute the controlling unstable equilibrium point, a practical and rigorous solving scheme was presented: by identifying the controlling load bus of the given fault, and using the Thevenin equivalent circuit to represent the rest of the system at the state of the post disturbance stable equilibrium point, using the steady equivalent circuit to represent the induction motor in composite load, and then using the torque characteristics of induction motor, a point near the CUEP is gained to be the initial value. The second order normal forms was used to approximate the stable manifold of CUEP, and the local approximating boundary of the region of attraction of the post disturbance stable equilibrium point was gained. Then just by simulating the state of the system at the fault clearing time, the transient voltage stability of the system could be determined.

针对采用牛顿法求取故障后系统主导不稳定平衡点(controlling unstable equilibrium point，CUEP)存在的初值选取难题，提出一种实用但不失严谨的解决方案：通过识别给定故障的主导负荷母线，对主导负荷母线以外系统由故障后稳定平衡点处的状态进行戴维南等值，对负荷中感应电动机部分采用其稳态等值电路，再由感应电动机的转矩特性求得CUEP附近的一个点作为近似的CUEP，以此为迭代初值可靠求得CUEP；采用二阶正规型来近似CUEP的稳定流形的方法求得近似的局部吸引域边界；由仿真得到故障清除时刻系统的状态并根据该状态是否位于吸引域内判断系统的暂态电压稳定性。

Unfortunately, there is inevitably difference in characteristics of the induction motors and converters in a parallel AC drive system, therefore each induction motor as well as converter can not operate at the same working point, some may be overload, some underload.

并联着的各个交流调速系统的负载是不均衡的，这是因为逆变器所带的负载—异步电动机参数及特性不可避免地存在差异，两或多台逆变器作为电源，其等效参数也很难一致，各驱动轮径总存在偏差，因此各台逆变器的输出电流和各台异步电动机的定子电流是不相一致的，有的逆变器、异步电动机可能过载，有的还可能欠载。

And then adding NAA at low concentration in MS was used to give rise to roots. We also found that lower level of hormone could control effectively browninng and vitrifaction during the culture and G1 n (6mg/L) and AgNOj (2mg/L) supplemented in shoot induction media could improve the shoot information rates apparently (about90%).The whole period of plant regeneration from leaflets of peanut could be divided as five steps: germination - shoot induction -shoot elongation-rooting- tranplant.
