The cold-end system of steam turbine is an important auxiliary system in thermal power plant, its operating mode has a direct impact on the output of the unit and auxiliary power. This paper uses an optimization analysis method to calculate the cold-end system of a 1000MW ultra-supercritical(USC) unit, and establishes a cold-end optimization system by using VB6.0 for a domestic ultra-supercritical unit, which provides an online guide for the operator by calculating the condenser. The results show that this system can provide some guidance for unit operation.
