Optimal Economic Scheme Selection and Characterisitc Curve Analysis for Condenser of 600MW Unit

Due to the limit of the increase unit's initial parameters,many countries attach importance to the increase of the unit's benefit.So how to assure secure operation of condensers is the important thing,when people sign make or operation condenser.Since this thesis studies the optimal economical operation project under the different cooling rate and numbers of flow.Takes a certain 600MW steam turbine for example,it is seventy for cooling rate and two for flow for the optimal project.In addition,this thesis draws and analyses the characteristic curves under the different flux and temperature of cooling water with the software of Matlab.The conclusion which relies on the characteristic curves can offer great reference for the economical operation of steam turbine.
