摘　　要：对电力系统仿真软件PSASP的结构和作业数据库进行了剖析,开发了能自动循环调用其暂态稳定计算模块和访问其计算数据的接口。针对传统基于单机单负荷模型的低频减载方案整定方法的缺陷,将所开发的接口应用到基于时域仿真的方案优化程序和方案校核程序的编写。最后对某地区电网进行低频减载方案整定计算和方案校验。仿真结果表明,所述接口对增强PSASP的计算功能和提高计算效率,降低现场工作人员工作量具有很好的效果。The architecture of Power System Analysis Software package （PSASP） and its database are dissected, then an interface, which can call transient stability calculating module of PSASP automatically and cyclically and access PSASP＇s calculation data, is developed. To remedy the defects in the setting method of traditional under frequency load shedding （UFLS） scheme based on single-machine and single-load model, the developed interface is applied to the time-domain simulation based programs to optimize and check the UFLS scheme. Finally, the developed programs are utilized to the setting and checking of UFLS scheme for a certain regional power network. Simulation results show that the developed interface can enhance the calculation function of PSASP and improve its calculation efficiency as well as reduce the workload of field personnel.
