摘要:

摘要:针对680 MW机组调峰时脱硫系统增压风机动叶调节系统不能投入自动的问题,采用引风机导叶执行器反馈信号作为前馈信号对单回路增压风机动叶自动调节系统进行改进,并提出了调节系统参数的整定原则。改进后,机组调峰过程中增压风机动叶调节系统可以十分可靠地自动投入。

Abstract:To solve the gas desulfurization system booster fan variable rotor blade system fails to automatically start while 680 MW unit peak regulation,the author adopted the feedback signal as feed forward signal to improve the single circuit booster fan variable rotor blade system, and indicated the setting principle of rotor blade varying parameters.After improvement,the booster fan variable rotor blade system starts automatically while peak regulation.
