基于阻尼转矩分析法的广域阻尼控制器设计
The study of design of wide area damping controllers based on DTA method
摘要
Abstract
The concept of damping torque analysis (DTA) is established on the basis of the generator rotor movement, and its physical meaning is clear. This paper extends the damping torque analysis to power systems with time delays, derives the DTA model of wide-area damping controller considering the time delay, studies the mechanism of the impact of wide-area damping controller on system damping with time delay, and proposes the time delay characteristic representation index. On this basis, from two aspects of the wide-area delay signal’s selection and the controller parameters tuning, the configuration of wide-area damping controller considering time delay is derived, the WADC’s configuration optimization process is described by examples, and it is concluded that the delay’s impact on controller’s angle seem to be greater than on the controller’s magnification. It also proves the correctness and feasibility of the configuration of the wide-area damping controller considering time delay based on DTA.关键词
