Abstract
An induced draft fan frequency converter fault during the operation of a CFB unit, the furnace pressure fluctuates greatly in the process of the fan switching from frequency conversion mode to power frequency mode automatically. By mean of analyzing the reasons of the abnormal event, corresponding improvement measures were put forward and the experience and lessons were also summarized. It provides a reference for preventing the occurrence of such events and dealing with similar events quickly for thermal professionals. Meanwhile, thermal workers could be reminded to pay attention to distributed control system (DCS) configuration management and the test work after configuration.
