Abstract

Through the analysis of the economic development situation in China and the characteristics of power structure in recent years, the electricity demand situation in China in the next 20 years was predicted with using electricity elasticity coefficient. Based on the five feasible power development programs, the water consumption of thermal power plants in the next 20 years were predicted and analyzed. The results show that, in the future thermal power construction in China, the DC cooling unit should be gradually reduced, the subcritical, supercritical, and ultra supercritical units should be constructed speedily, as well as the application of direct cooling technology with sea water in coastal region and the air-cooling technology should be strengthened. In addition, the development and large-scale application of water-saving technology should be also strengthened.

Key words
