Abstract:

In boiler No.1 of a power plant, the communication fault of the frequency converter for induced draft fan B occurred repeatedly. The reason of the

fault was analyzed and searched; and it was verified finally that the fault reason is that the connection of the plugin connectors between the fiber

communication mother board and the fiber communication daughter board in master control system was loose. The treatment method of the converter communication

fault was introduced; and some suggestions on converter operation were given.
