摘要
电力系统异步运行和再同步过程比较复杂，时间校长。发电机、励磁和调速系统不采用较精确的数学模型就不能真实地反映该过程。为此，本文编写了采用较精确数学模型的多机电力系统再同步过程数字仿真程序。并以四机系统为例进行了计算。计算结果与以前大量文献分析和实验所得的物理过程相吻合，从而为进一步的再同步控制研究准备了条件。
Processes of asynchronous and resynchronous operation in power systems are complex,and their times are longet.For really reflecting the preeesses,accurate medels of generators,excitors and govemors must be selected. Therefore,a digital simulation program,in which the accurate modeis are adopted,has been written in this paper.calculation results of a 4-machine system are fitted with the experiment re-sults. Then,the program prepares the conditions for further resynchronization control studies.
