为了节能和提高能源利用率，锅炉风烟系统采用了3台电动引风机，从而出现了常规双引风机的平衡偏置控制策略不适用于炉膛压力控制，且无法实现3台引风机之间的平衡控制的问题。对此，通过在Ovation DCS上开发IDFBALANCER宏模块，很好地解决了3台引风机间的平衡控制问题，并且提高了在改变自动控制方式的引风机数量时，炉膛压力调节回路的自适应能力。
為瞭節能和提高能源利用率，鍋爐風煙繫統採用瞭3檯電動引風機，從而齣現瞭常規雙引風機的平衡偏置控製策略不適用于爐膛壓力控製，且無法實現3檯引風機之間的平衡控製的問題。對此，通過在Ovation DCS上開髮IDFBALANCER宏模塊，很好地解決瞭3檯引風機間的平衡控製問題，併且提高瞭在改變自動控製方式的引風機數量時，爐膛壓力調節迴路的自適應能力。

To enhance the energy utilization efficiency,three motor-driven induced-draft fans (IDF)are ap-plied,causing problem taht the balance bias control strategy of the conventional double-IDF is not applica-ble to furnace pressure control.Moreover,balance control of the three IDFs can not be realized.Thus,by developing macro module IDFBALANCER in Ovtaion DCS,the balance control problem among the three IDFs was well solved,and the control loop's adaptive ability with different auto IDF's numbers was en-hanced.
