摘　　要：为提高机组运行经济性和节能减排,国电谏壁发电厂2×1 000 MW超超临界机组工程在设计过程中采取了大量的优化方案,对一些传统的设计理念和运行模式有所突破,值得其他工程参考和借鉴。主要的优化方案:①在1 000 MW机组上采用国产化DCS设备;②在电力建设中采用浮运钢壳沉井方案来施工循环水泵房;③在1 000 MW机组循环水泵系统采用单元制一机四泵配置;④总平面布置在1 000 MW机组中占地面积最小;⑤对新旧煤场进行优化整合、合理优化主厂房地基处理等。工程投产后,机组性能指标总体上处于国际先进水平,部分技术和指标达到了国际领先水平。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.
