Abstract: Many optimized solutions have been applied in the design of two 1 000-MW units of Guodian Jianbi Power Plant to improve the plant’s operation economics and achieve the goal of energy-saving and emission-reduction. These solutions have made certain breakthroughs in the traditional design philosophy and operation model, which are valuable even for other projects. The main optimized solutions are listed as follows. First, the domestically-manufactured DCS is adopted in the units. Second, the floated steel shell well sinking scheme is used to build the circulating water pump house. Third, the four-pump-in-one-unit configuration is deployed in the circulating water pump system. Fourth, the land occupation of the plant is the least among those with 1 000-MW capacity units. Finally, the old and new coal storage areas are integrated and the treatment to the main building foundation is optimized. Since the unit commissioning, the performance indices of the power plant have reached the international advanced level with some technologies and indices even at the leading edge internationally.

Key words: thermal power unit, 1 000 MW, design optimization, design characteristic
