摘要
针对稳定计算用发电机励磁系统参数测试建模,在分析励磁控制系统各部件模型参数的基础上,提出了适合于工程实际应用的测试建模及校核分析方法,并结合具体的现场试验,给出了试验结果分析及仿真计算校核示例,得到了符合稳定计算要求的发电机励磁系统模型参数。
Based on the analysis of excitation system model for power system stability studies, this paper proposes the methods for building computer representation of excitation system and checking the precision of the model.Firstly, the transfer function model of each part on excitation system is gotten and the parameters of this model are calculated. Then, the result of step response on no-load condition between field test and simulation is analyzed, the error should be on the range of being allowed.On this basis, contents of parameter measurement and calculation, principles of modeling and check in project application are proposed.Finally, a detailed example is given.
