摘　　要：提出直角坐标下电压崩溃临界点计算的非线性规划模型，并充分利用该模型的二次性，对基于对数障碍函数的预测校正原—对偶内点法进行改进，最后通过对ＩＥＥＥ—３０节点测试系统的仿真计算验证了该算法的有效性。This paper proposes a nonlinear programming model in perpendicular coordinate to calculate critical point of voltage collapse. By utilizing the quadratic character of nonlinear programming model, the logarithmic barrier functions based predictor-corrector primal-dual interior point method is improved. Simulation on IEEE-30 bus test system shows the effectiveness of the improved algorithm.
