Abstract
Description
technical field
[0001] The present application relates to the field of automatic control, in particular to a valve control system and control method. Background technique
[0002] The boiler is one of the key equipment of the thermal power plant system. Whether the boiler is in a safe and stable operating state is directly related to the normal operation of the thermal power plant. There are many factors that affect the operating state of the boiler, including the steam pressure, temperature, and air volume in the boiler. The safe and stable operation of the boiler can be ensured by controlling the steam pressure, temperature, and air volume in the boiler. Wherein, the steam pressure in the boiler is generally controlled by setting a pressure valve and controlling the opening and closing of the pressure valve.
[0003] However, in current systems for controlling steam pressure in boilers, the pressure valve is connected to only one control device, and if the control device ...
