摘要
对直接求取电压崩溃临界点的零特征根法进行扩展，将临界点计算转化为非线性规划问题，并用预测校正原对偶内点法求解。该方法能够考虑各种不等式约束条件，因而具有较强的鲁棒性。文章还证明了零特征根法事实上是非线性规划法的一个特例。最后通过对ＩＥＥＥ－３０及ＩＥＥＥ－１１８测试系统的仿真计算验证了该模型及算法的有效性。
This paper develops zero eigenvalue method for the solution of point of collapse (PoC). It converts the calculation of PoC to a nonlinear programming problem, which is solved by predictor corrector primal dual interior point method in this paper. The approach proposed is affable to dispose of all kinds of inequality constraints and shows its robustness. It is also proved that zero eigenvalue method is just one special case of nonlinear programming method. The approach proposed has been successfully tested on the IEEE 30 and IEEE 118 systems.
