Study on the Energy Consumption Distribution of 1000MW USC Unit

Abstract:

In recent years, the 1000MW ultra-supercritical unit has developed rapidly for its high efficiency and low energy consumption in china. In order to further reduce the energy consumption, the energy consumption distribution of a typical ultra-supercritical unit is analyzed in detail, which can make contribution for the energy conservation of units. Based on the theory of unit energy consumption and according to the thermodynamic calculation of a 1000MW ultra super critical generating unit under the design condition and off-design loads, this paper reveals the distribution of energy consumption rules of the whole unit, including every subsystem. The results indicate that when the load deviates from the design load, the total energy consumption of system will increase.
