Variable frequency reformation of condensate pump for 600MW supercritical steam turbine

The variable frequency reformation of the condensate pump of 600MW supercritical unit and its energy-saving effect were analyzed.On the basis of warranty for safe operation of the condensate pump,the 'one drive one' mode was adopted in the variable reformation of the condensate pump.The operation data after reformation show that the reformation scheme achieves the design requirements,the power consumption of the condensate pump reduced by 36%,and the house-service consumption rate was reduced by 0.12%,the energy-saving effect is remarkable.
