| description | The invention relates to an efficiency display method and system for a water feed pump turbine. The method comprises the following steps that 1, operation measuring point data and operation experience data are obtained; 2, thermodynamic calculation is carried out on the water feed pump turbine steam inlet enthalpy, the water feed pump turbine steam inlet entropy, water feed turbine steam exhaust, the water feed pump inlet enthalpy and the water feed pump outlet enthalpy; 3, performing formula calculation under the condition of working condition division based on the operation experience data and the operation measuring point data to obtain the final feed pump and feed pump turbine efficiency; and 4, outputting and displaying the final feed pump and feed pump turbine efficiency. The method can be used for displaying the real-time efficiency of the feed pump turbine in an SIS system or a DCS system, the performance degradation condition of the steam feed pump set is monitored in real time through the applicatio |
