电解铝生产过程中容错控制策略研究

摘要

通过研究电解铝生产控制策略,提出了一种总调/分调控制模式和容错控制策略,以弥补容错控制在铝业生产中的空白.当整流机组发生非严重性故障后,在保证设备安全、可靠运行的前提下,可采取限负荷、保温等容错控制策略,通过自动化手段避免将事故扩大.如果容错控制无法消除异常,则采取系列跳闸保护措施,将故障引起的损失减少至最小.%After investigating the control strategy for electrolytic aluminum production, a novel total/ part control mode and fault tolerant control strategy were proposed. In the premise of safe and reliable service, the fault-tolerant control strategy like load limit or heat preservation can be applied so as to avoid accident expansion , otherwise, the serial tripping protection measures can be used to protect the equipment and reduce the loss to a minimum.
