摘要
通过对脱硫增压风机变频改造,使增压风机由长期恒速运行转变为自动变频变速运行,改善了电机启动特性,提高了厂用电系统的稳定性和脱硫系统故障后的快速恢复,并取得了显著的节能效果。
Based on the frequency transformation of desul- phurization booster fan, the long-term constant speed operation of the booster fan is changed into the automatic variable speed operation, which improves starting characteristic of motor, im- proves the rapid recovery of the station service system stability ＆ desulfurization system after fault and has achieved remarkable energy-saving effect.
