METHOD FOR CALCULATING MAIN STEAM FLOW IN TURBIN PERFORMANCE TEST AND TURBIN PERFORMANCE TEST DEVICE USING THE SAME

摘要

The present invention relates to a method for calculating a main steam flow rate in a turbine performance test and a turbine performance test apparatus using the same. The method for calculating a main steam flow rate in a turbine performance test according to an embodiment of the present invention includes a plurality of flow rates at the inlet of a deaerator. Selecting and measuring a reference flow rate for calculating the mass balance and heat balance of the cycle; Deriving a mass balance calculation formula including the reference flow rate and a heat balance calculation formula as a calculation formula between settlement symbols; Determining a final water supply flow rate (MFW) by performing passion calculation based on a sequential approach by combining the mass balance calculation equation and the heat balance calculation equation in order to resolve the mutual reference between the settlement symbols; And calculating the main steam flow rate using the final feed water flow rate.
