摘要/Abstract

摘要： 针对电解铝负荷在响应电力调频信号时存在整流器抽头运动延时造成响应精度低的问题,提出了一种信号缩减方法——运动控制阈值法,结合整流器抽头动特性对调度参考调频信号进行缩减,缩减信号作为电解铝负荷控制的输入,能够有效提高电解铝负荷参与调频的响应绩效。设计了一种基于仿真的控制阈值优选方法,优选阈值参数用于电解铝调频容量决策,仿真验证了缩减方法将电解铝调频绩效提升到生产水平的有效性和阈值优选方法对电解铝负荷调频决策的适用性。

Abstract: The motion delay of tap changer of aluminum smelter rectifier downgrades frequency response precision in following high frequency regulation signals.Aiming to improve the regulation performance of aluminum smelter loads based on adjusting dynamics,a fast regulation signal reduction technique is proposed,which is motion control threshold-based.A simulation-based decision technique of threshold values of the signal reduction algorithm's is devised to improve the performances of frequency response.Simulation results verify the efficacy of the techniques in promoting the frequency response precision to a certain production level,and contribute a practical way to support aluminum smelter‘s provision of frequency regulation services as well.

Key words: aluminum smelter, frequency regulation, signal reduction, threshold, demand response resources
