| 摘 要： | 提出一种用于支路故障情况下静态电压稳定临界点计算的可靠方法。该方法以支路导纳系数为连续性参数,采用类似连续法的预测校正格式,可沿着临界点曲线从故障前系统的电压稳定临界点追踪至各支路故障后的临界点。其中预测及校正方程均采用特殊的矩阵降阶技术求解,所需求解的方程组维数只相当于原来的一半。在IEEE 14及1000母线系统上的算例验证了该文方法的可行性与高效性。

| Abstract: | This paper presents a reliable method to calculate the critical point of static voltage stability under branch outage contingency. With branch admittance as the continuation parameter, this method can trace through the critical curve, which is made up of critical points, from pre-contingency case to post-contingency case using predictor and corrector. All equations in prediction and correction step can be solved using matrix reduction technique, which significantly reduces the dimension to half of the original. Tests on IEEE 14 and 1000 bus system verify the feasibility and efficency of this technique. |
