摘　　要：轨迹灵敏度法是分析电力系统暂态稳定性的重要方法之一,通常需要大量的时域仿真计算。为解决时域仿真中故障设置繁琐、重复操作量大、迭代耗时长的问题,采用Matlab对PSASP暂态稳定计算程序进行调用和数据交换的方法,实现了PSASP时域仿真与暂态稳定分析交互式计算的一体化。给出了直接在Matlab中一键式调用PSASP计算暂态稳定的步骤。计算结果表明,通过Matlab直接对PSASP暂态稳定计算文件进行修改和调用计算可较好地减少迭代计算的耗时;以基于轨迹灵敏度法求解无功补偿优化配置的方法为例,在改进的10机39节点系统中验证了该方法的高效性。Trajectory sensitivity is one of the important methods to analyze the transient stability of power system, and a large number of time domain simulation calculations are required. Considering the complex fault settings and repeated operations as well as time consum- ing, the way of calling and data exchange for transient stability calculation of PSASP via MATLAB is applied to realize the integration of time domain simulation in PSASP and transient stability analysis, the steps of invoking Power System Analysis Software Package （PSASP） to calculate transient stability with one click in MATLAB are proppsed. Resuhs show that time-consuming of iterative computation can be improved by revising and invoking the transient stability calculation file through MATLAB ; Taking the optimization of reactive power com- pensation based on trajectory sensitivity method as an example, the high efficiency of the method is proved in improved IEEE39 system.
