VPSSAP软件在电压稳定仿真研究中的应用

Applications of VPSSAP in Simulation Research on Voltage Stability

目前许多求解电压稳定极限的算法都存在着计算量过大的问题,为此,提出一种基于VPSSAP软件的静态电压稳定极限计算方法,通过VPSSAP软件提供的潮流计算模块,采用负荷导纳模型,能有效地计算出静态电压稳定极限,对IEEE22节点系统的计算验证了VPSSAP软件的有效性和实用性。

At present, many algorithms for solving voltage stability limit involve excessive computing; therefore, a method for computing the voltage stability limit based on VPSSAP is presented. This method, using the load flow calculation module supplied by VPSSAP and adopting admittance model in load bus, can compute the voltage stability limit effectively. The effectiveness and practicality of VPSSAP are verified by the calculation on IEEE 22 node system.
