再热汽温度控制方法及装置
摘要：
本发明涉及热工控制领域，公开了一种再热汽温度控制方法及装置，其中所述方法包括：接收喷水减温对再热汽温度的控制量、烟气挡板对再热汽温度的控制量以及燃烧器对再热汽温度的控制量；由所述再热汽温度的温度预测模型根据所述喷水减温对再热汽温度的控制量、烟气挡板对再热汽温度的控制量以及燃烧器对再热汽温度的控制量而输出下一时刻的温度值；以及根据所述下一时刻的温度值与该下一时刻的预设值之间的差值来确定应施加的控制量以控制所述再热汽温度。通过根据该计算的应施加控制量来对系统施加控制动作可以有效保证再热汽温度满足系统要求。
摘要（英）：

The invention relates to the field of thermal control and discloses a reheat steam temperature control method and a reheat steam temperature control device. The method includes: receiving reheat steam temperature control quantity of spray desuperheating, reheat steam temperature control quantity of a smoke damper and reheat steam temperature control quantity of a combustor; allowing a reheat steam temperature predication module to output a temperature value of the next moment according to the reheat steam temperature control quantity of spray desuperheating, the reheat steam temperature control quantity of the smoke damper and the reheat steam temperature control quantity of the combustor; determining a to-be-applied control quantity according to a difference value between the temperature value of the next moment and a preset value of the next moment to control reheat steam temperature. By application of control actions to a system according to the calculated to-be-applied control quantity, system requirements of the reheat steam temperature can be met surely.
