根据稳定性要求合理选择HVDC中数字式PID控制器的参数

THE SUITABLE CHOICE OF THE PARAMETERS OF THE DIGITAL PID CONTROLLER IN THE HVDC SYSTEM REQUIRED BY THE STABILITY

介绍数字式ＰＩＤ控制器在ＨＶＤＣ系统运行控制中的应用，并以定电流、定关断角控制为例论述了根据系统运行的稳定：性要求来选择数字式ＰＩＤ控制器参数的技术，还给出了根据该方法设计的数字式控制器在直流输电摸拟系统中运行的部分结果。

This paper presents the applicatiun of the digital PID controller on the HVDC system. Such asconstant current control and constant extinction angle control,the technique of choosing the parameters ofthe digital PID controller required by the stability is introduced. Performed by the digital controller designedaccording to the stable requisition,a part of the HVDC simulation’s operation are showed at the end of thepaper.
