GB/T 7409.2-2008 in English

《GB/T 7409.2-2008同步电机励磁系统 电力系统研究用模型》由TC26（全国旋转电机标准化技术委员会）归口，主管部门为中国电器工业协会。
ＧＢ／Ｔ７４０９《同步电机励磁系统》分为三个部分，本部分是ＧＢ／Ｔ７４０９《同步电机励磁系统》的第二部分，于１９８７ 年第一次制定，１９９７ 年第一次修订，本次版本为第二次修订。ＧＢ／Ｔ７４０９的本部分规定的励磁系统模拟简图及相应的数学模型，以及其中包括的参数和变量的术语定义适用于电力系统稳定性研究。与ＧＢ／Ｔ７４０９．２―１９９７比较，本部分主要变化如下：
―――对励磁系统模型作了具体描述，所建立的发电机励磁系统模型能够满足国内主要的发电机励磁系统进行电力系统稳定分析之用；
―――补充了校正环节、电力系统稳定器模型；
―――描述了限制器和电力系统稳定器作用于电压调节器的方式。
