摘要
电力系统物理模拟是电力系统科学研究的重要手段之一,但由于制造上的因素使动模发电机组不能完全与实际设备的参数相同,因此需要通过调节器来实现一些模拟功能。该文比较了几种传统方法,提出了一种新颖的改变发电机转子时间常数的方法,在已有的励磁控制器中增加励磁电流电压综合反馈数学模型,用软件算法来实现改变转子模型的目的,整套装置结构简单,操作方便,具有较高的精度,通过仿真和实际模拟机组运行实验进一步验证了该方案新颖、实现简洁可行。
Physical simulation of power system is one of important means of power system research. Because of the difficulty of manufacturing, model generator＇s parameters are not Completely as the same as the actual devices, we need regulars to realize some functions. In this paper,we have compared some typical methods in change generator model time constant. On the basis of simulation and experiment,we educed a novel and powerful method,which can be a additional part of exciter controller.
