查询词典 main unit

By setting up the mathematical models of the regulating objects （combusting heat transfer, heat utilization and storage, superheater and main steam pipe line）, by combining heat transfer function of regulating system and by selecting method of setting PID accoding to set attenuation index object, the corrections among PID and pulverized coal＇s caloric values are found. Now the PID can be set according to caloric values of the pulverized coal burned in the unit and the automatic control can be put into operation.

通过建立调节对象四个环节（燃烧传热过程、热量的利用和储存过程、过热器、主蒸汽管道）的数学模型，结合调节系统的传递函数，选用按给定衰减指数设定PID参数的方法，找出PID参数与煤粉热值的关系式，最终达到在机组燃烧不同热值的煤粉时可依据该方法设定不同的PID参数、并都能投自动的目的，从而有利于提高机组的稳定性，并可节约煤粉。
