摘要
结合韶关发电厂引风机变频改造项目,从控制角度,介绍了使用高压变频调速装置对引风机进行变频改造的方案和变频改造后引风机变频控制和自动调节的方案。
This article unifies the project of the IDF frequency reconstruction in Shaoguan Power plant, from the control angle, introduced the use of high-voltage frequency conversion device for conversion of the IDF modification program and the control and automatic adjustrnent programs after the Transformation.
