本文提出了一种自适应控制策略,以改善电力系统设备的应力瞬态响应。该策略基于启用校正的设定点自动调整(SPAACE),是一种辅助控制方法,用于增强设备的设定点跟踪。SPAACE使用来自可控装置的输出的反馈信号来修改可控装置的设定点,以减轻可能由诸如故障、负载变化和大的参考设定点变化之类的事件引起的瞬变。在这项工作中,引入了自适应版本的SPAACE(ASPAACE),它使用自适应死区带,自适应缩放因子和指数预测。此外,本研究探讨了系统的固有频率和ASPAACE控制器的预测范围之间的关系。为了证明ASPAACE的性能,不同的案例研究。
This paper presents an adaptive control strategy to improve the transient response of a stressed power system apparatus. This strategy, based on the set point automatic adjustment with correction‐enabled (SPAACE), is an auxiliary control method to enhance the set point tracking of an apparatus. SPAACE modifies the set point of the controllable apparatus using a feedback signal from its output to mitigate transients that can be caused by events such as faults, load variations, and large reference set point changes. In this work, an adaptive version of SPAACE (ASPAACE), which uses an adaptive dead‐zone band, adaptive scaling factor, and exponential prediction is introduced. Moreover, this study investigates the relationship between the natural frequency of the system and the prediction horizon of the ASPAACE controller. To demonstrate the performance of ASPAACE, different case studies are presented.
