摘 要 本文以两台柴油发电机组并联的电力系统为例建立了船舶电站并联系统的的机电暂态过程数学模型,应用求解发电机转子运动方程为核心的暂态稳定性分析方法,研究了并联系统在切除、投入大容量负载后的动态特性,结合一个算例进行了数字仿真,并从仿真结果可知调节原动机调速器和发电机励磁调节器的参数可以改善系统的稳定性。
Abstract :In this paper ,to take the parallel power system consisted of two diesel generators as an example ,the mechanical2electrical transient course mathematics model of the shipping power plant parallel system is founded. Using transient stability analysis method which is the core of solution of generator rotor movement equations ,dynamic characteristic is studied when the parallel system is loaded and unloaded with the big capability load. The result s from a digital simulation example show that the system stability can improve through adjusting the parameter of the prime mover speed regulator and the exciting regulator.
