Optimized Operation of 2×660 MW Piping-Main Scheme Circulating Water System

Abstract:

The existing optimized operation of circulating water system does not suit piping-main scheme circulating water system with double-pressure condenser. The optimum vacuum of piping-main scheme should be defined as the vacuum which makes the difference between the sum of the two units’ added electric power and the circulating water pump power maximum. The plan of optimized operation of piping-main scheme circulating water system which is based on this kind of optimum vacuum was put forward. And a specific example of 2×660MW units was given, the power plant’s optimized operation mode of the whole circulating water system at difference conditions was obtained. The results show that the optimized scheme is correct and suit the piping-main scheme circulating water system, and the optimized operation can well improve the steam turbine economy.
