Abstract: Abstract:The measurement deviations of the main steam flow and the feed water flow of a 330MW thermal power unit were analyzed. The main steam flow function was amended, and the temperature correction was done for the feed water flow. The deviations were eliminated, and the unit performance in energy saving and consumption reducing was improved.
