| 摘 要： | 提出对多台发电机参数进行整体辨识的思路,即根据广域测量系统（WAMS）采集到的发电机的功角轨迹,同时辨识多台发电机的参数。文中针对不同阶次的Park模型,采用基于轨迹灵敏度的可辨识性分析方法,研究了多台发电机参数的可辨识性,结果表明大部分参数能够区分辨识而一部分参数不能够区分辨识。提出了多台发电机参数的辨识策略,以及基...

| Abstract: | A system-wide identification methodology for multi-generators in power systems is proposed,i.e.to identify the parameters of multi-generators simultaneously with the rotor angle data from wide area measurement system(WAMS).The parameter identifiability of different Park models is analyzed by using the trajectory sensitivity method,and the results indicate that most of the parameters are identifiable but some of the parameters are not identifiable.The strategy is developed for the simultaneously identificati... |
