摘要
汽轮发电机采用静止励磁方式使轴系缩短并减少了一个质块 ,是否可以去掉有危害性的扭振频率而改善串补系统中次同步谐振安全运行区范围的问题为工程技术人员所关心。本文从原理上对此进行了研究和分析。首先对汽轮发电机的轴系建模进行了说明 ,然后以IEEE次同步谐振 (SSR)标准模型和东北电网中伊敏电厂计划安装的 5 0 0MW和 60 0MW汽轮发电机组为典型算例 。
It was in doubt for long time whether by using the static excitation could improve Subsynchronous Resonance (SSR)condition in a certain power system with serial compensation.In this paper,this problem is studied theoretically.First the model of turbogenerator's shaft is constructed.Then we use IEEE first benchmark system model and the 500kV system,which contains 500MW and 600MW turboge nerators,as typical examples.And the shaft systems without exciter in these examples are also analyzed on its impact on torsional oscillation.
