摘　　要：随着电力系统规模的增大,相关模型的日趋复杂,电力系统分析软件已成为电力工作者不可缺少的有力工具。同时,如何充分利用电力系统计算软件提供的函数模块,将其进行有效地组织、搭建,满足工程上的需要已成为电力工作者亟需掌握的一项技能。文章比较系统地介绍了一种用PSS/E软件求解大规模电网最大负荷极限点的方法,由于在求解过程中较为全面地考虑了影响负荷极限的各项因素,使得计算结果更贴近实际,所得指标也更具有指导意义。最后通过算例验证了所提方法的有效性和可行性。As the scale of electric power system become more and more expanding and the model of electrical power devices become more and more complicated, electrical power system analysis software （EPSAS） has become an indispensable tool for electrical power researchers. At the same time, how to make best use of its application program interface （API） and how to arrange and construct it effectively for satisfying the demand of project become an important skill for electrical power colleagues. In this paper, a method is introduced for determining maximum loading limit for large scale power system by PSS/E simulation software. Since various factors which have impact on loading limit are taken into consideration, the program is more close to real system and makes the index more instructive. At last, a study case is simulated for testing the effectiveness and feasibility of the proposed method.
