摘要
利用复数表面阻抗的概念给出了发电机转子负序涡流场二维分析与计算方法,在此基础上,编制了相应的计算程序.以转子极面加阻尼系统的300MW汽轮发电机为例,计算了发电机稳态负序运行时转子上的涡流分布和损耗分布.根据计算结果,讨论了转子极面加阻尼系统对提高发电机负序能力所起的作用.
A method for two dimensions analysis and calculation of rotor negative sequence eddy current field is presented by using the complex surface impedance concept. The calculation program is compiled based on the analysis. As an example, the distributions of eddy currents and losses in the rotor of turbo - generator running on steady unbalanced load are calculated for 300MW turbo - generator of rotor pole with damping system, and according to the results, the rotor pole combined with damping system for increasing the negative sequence capability of the machine is discussed.
