    • A steam turbine plant includes an extraction system and a control system for controlling the steam extraction. The extraction system includes an extraction steam flowmeter and a stop valve. The control system sets a warning flow and an extracted steam stop flow for the extracted steam. When the extracted steam flow reaches the warning flow, a warning is issued and after a lapse of a predetermined time period, the stop valve is opened to restrict the extracted steam flow. When the extracted steam flow reaches the extracted steam stop flow, the stop valve is closed to stop steam extraction. A steam turbine plant can thus exercise extraction control to stably supply extracted steam while avoiding turbine trip, even if not equipped with a high-performance and expensive valve device such as an extraction steam control valve.
    • 蒸汽轮机设备包括提取系统和用于控制蒸汽提取的控制系统。 提取系统包括提取蒸汽流量计和截止阀。 控制系统为提取的蒸汽设置警告流和提取的蒸汽停止流。 当提取的蒸汽流量达到警告流量时,发出警告,并且在经过预定时间段之后,打开截止阀以限制提取的蒸汽流量。 当提取的蒸汽流量达到提取的蒸汽停止流量时,关闭截止阀以停止蒸汽抽出。 因此,蒸汽轮机设备可以运行提取控制以稳定地供应提取的蒸汽,同时避免涡轮机跳闸,即使没有配备高性能和昂贵的阀装置,例如抽取蒸汽控制阀。
