摘要
研究ＨＶＤＣ系统直流侧综合有源直流滤波器（ＡＤＦ）控制器的关键是确定被控对象的数学模型。然而，由于运行工况及气候的影响，难以求取换流器及长距离高压架空线路在音频带内的动态数学模型。文章针对这一问题，在介绍ＡＤＦ控制原理的基础上，提出一种用系统辨识技术估计对象模型参数的方法，并通过仿真实验证实了这种方法的可行性及受辨识模型参数的有效性。
The key problem in the synthesis of the controller design for active DC filters(ADF) in DC side of converter station is to obtain the mathematical models of controlled device. It is difficult to obtain the dynamic models of converters, overlong overhead HVDC lines and passive filters in audio frequency. For this reason, based on identification technology the estimate model parameters of controlled device in ADF are presented in this paper. Simulation results show that this approach to obtain device models is feasible and effective.
