摘　　要：提出塔式太阳能与燃煤机组复合发电系统的优化集成方案,建立复合发电系统技术经济性评价的分析计算模型,以330 MW机组为例,对3种集成方案的技术经济性进行模拟计算。结果表明,塔式太阳能与燃煤机组复合发电系统的热功转换效率高于纯塔式太阳能低于燃煤机组,通过单方案判断、多方案比选和财务盈利能力的分析得出,塔式太阳能产生的蒸汽引入燃煤机组主蒸汽是较理想的选择,其热功转换效率约为42.8%,太阳能净发电成本为2.68$/k Wh。The optimization and integration scheme of solar tower power with coal-fired hybrid power plant was put forward, and the techno-economic model of hybrid power system was established. A case study of a 330 MW unit with three integration schemes was evaluated by techno-economic analysis. The results showed that solar tower power with coal-fired hybrid power plant in various applications is feasible; the thermal cycle efficiency of hybrid power system is higher than the only solar tower power station and lower than coal-fired power system. Through judging from single case, cases comparison and financial profitability analysis, the best choice is leading the steam produced in the solar tower to the main steam of coal-fired unit. Cycle thermal efficiency of power generation systems is 42.8% and net cost of solar power is 2.68 yuan RMB/kWh.
