汽轮发电机Canay模型的仿真分析
Large Electric Machine and Hydraulic Turbine(2014)
Abstract
发电机的精确模型对于电机运行行为和机网相互作用的研究至关重要.Canay电机模型在传统电机模型的基础上考虑了链接励磁绕组和阻尼绕组的互感抗,能够更为准确地描述同步电机暂态特性.本文讨论了Canay电机模型的等效条件和计算方法,基于PSCAD/EMTDC软件,在电压调整、主变高压侧接地故障和FCB三种典型工况下,通过仿真分析比较传统电机模型和Canay电机模型对应的暂态特性的差异.仿真结果表明,在接地故障工况下,传统电机模型和Canay电机模型仿真结果的励磁电流差异较大,此时应采用Canay电机模型对电机做研究.
