为对电站锅炉过热汽温进行校正及辅助测量,以支持向量机算法对过热汽温进行软测量,利用历史数据建立过热汽温的软测量模型。软测量模型描述了过热汽温与机组负荷、汽包压力、给水量、燃料量等机组运行参数之间的关系,辅助测量仪表对过热汽温进行测量和校正,保证汽温在设定范围内,保证机组的安全运行。 In order to calibrate and assist the overheated steam temperature of power station boiler, a soft sensor model of superheated steam temperature was established based on the support vector machine (SVM) algorithm. The soft-sensing model describes the relationship between superheated steam temperature and unit operating parameters, such as unit load, drum pressure, water supply and fuel quantity. Auxiliary measuring instruments measure and correct the superheated steam temperature to ensure that the steam temperature is within the set range , To ensure the safe operation of the unit.
