摘要： In a steam system having a turbine driven by steam supplied from a high-pressure header to a low-pressure header, when the pressure in the low-pressure header drops, a turbine bypass valve is opened and the high-pressure side steam is supplied to the low-pressure side header in a normal control. When the turbine is tripped, steam is rapidly flow into the low-pressure side header and its pressure temporally increases. the steam in the low-pressure header is discharged through a discharge valve. After that, if a steam supply from the low-pressure header to another process increases, the discharge valve is closed. After the discharge valve is fully closed, an after-trip control is performed in which the opening of the turbine bypass valve is increased at an earlier timing than the normal control for preventing the steam amount in the low-pressure header to be too small. The control stability of the steam system when the turbine is tripped can be enhanced.
摘要翻译：在由从高压集管供应到低压集管的蒸汽驱动的蒸汽系统中，当低压集管中的压力下降时，打开涡轮旁通阀并供应高压侧蒸汽到正常控制中的低压侧集管。当涡轮机跳闸时，蒸汽迅速流入低压侧集管，其压力暂时增加。低压集管中的蒸汽通过排放阀排出。之后，如果从低压集管到另一个过程的蒸汽供应增加，则排放阀关闭。在排气阀完全关闭后，执行后续控制，其中涡轮旁通阀的打开在比用于防止低压集管中的蒸汽量过小的正常控制更早的时间增加。可以增强涡轮机跳闸时蒸汽系统的控制稳定性。

摘要： A steam system control method applied to a steam system including: a low-pressure header storing low-pressure steam; a high-pressure header storing high-pressure header; a steam turbine connected between them; and a turbine bypass line introducing controlled amount of steam from the high-pressure header to the low-pressure header by bypassing the steam turbine. The low-pressure header has a blow-off valve for discharging excessive steam to the outside. The steam system control method includes: a normal time blow-off valve control step of PI controlling the opening of the blow-off valve; and a trip time blow-off control step of controlling the opening of the blow-off valve by changing the MV value to a predetermined trip time opening set value when the turbine is tripped. According to this method, the opening of the blow-off valve is controlled based on the predetermined MV value when the turbine trips and excessive steam flows into the bypass, so that excessive steam flows into the low-pressure header is quickly discharged to the outside. Stable operation can be achieved even when a turbine trips.
摘要翻译：一种应用于蒸汽系统的蒸汽系统控制方法，包括：存储低压蒸汽的低压集管; 一个高压集管，储存高压集管; 连接在它们之间的蒸汽轮机; 以及涡轮旁通管路，其通过绕过所述蒸汽轮机将受控量的蒸汽从所述高压集管引入所述低压集管。低压集管具有用于将过量蒸汽排放到外部的吹扫阀。蒸汽系统控制方法包括：正常时间排放阀控制步骤，PI控制排出阀的打开; 以及跳闸时间吹出控制步骤，当涡轮机跳闸时，通过将MV值改变为预定跳闸时间打开设定值来控制排气阀的打开。根据该方法，当涡轮跳闸和过量的蒸汽流入旁路时，基于预定的MV值来控制排气阀的打开，使得流入低压集管的过量蒸汽迅速地排放到外部。即使涡轮跳闸，也可以实现稳定运行。
