摘要
介绍了电力系统暂态稳定性的基本概念以及电力系统综合程序(PSASP)的基本内容,提出了一种将发电机励磁调节器和电力系统分析综合程序用户程序接口(PSASP/UPI)相结合快速实现电力系统暂态稳定仿真的方法。用FORTRAN语言编写励磁调节器的用户程序(UP),通过接口传递数据,使PSASP/UPI环境下的暂态稳定仿真模块和该用户程序交替求解,准确模拟系统发生故障后发电机功角随时间的变化,以判断系统的暂态稳定性。通过实例验证该仿真方法实现了PSASP功能的扩充,可以有效应用于实际系统暂态稳定分析,且易于程序实现。
This paper described the concept of power system stability and the content of power system analysis software package（PSASP）. A fast method of getting transient stability simulation was presented combining an excitation regulator model with the power system analysis software package and user program interface （PSASP/UPI）. The user program （UP） of excitation regulator model,which is composed by FORTRAN language, then can be carried out with transient stability calculation by turns on PSASP/UPI through the interface transmitting data. So the changes of the generator angle with time can be simulated accurately. The example EPRI-7 power system verifies that the method can be used to analyze practical power system transient stability and easy to be programmed.
