摘要： 有机朗肯循环是最具潜力的低品位热-功转换技术之一，设计工况的选择和考虑变工况的系统设计和运行方法对降低系统全年发电成本或提高系统年均发电效率有重要意义.本文建立了余热驱动有机朗肯循环系统设备结构参数和系统运行参数同步优化模型并提出了求解策略；考虑到环境温度随季节变化的特性，选取4个环境温度作为设计工况，分别得到了4个设计工况下最优设计方案，基于4个设计结构优化全年运行方案，并比较不同系统配置下全年变工况的综合性能.研究结果表明：同时优化系统参数及设备结构参数对提高系统性能至关重要；环境设计温度不同，设计的最优结构和运行方案不同，可根据多个变工况环境温度对系统进行优化设计，优化全年运行方案.

关键词: 余热回收, 有机朗肯循环, 变工况, 系统全年性能

Abstract: Organic Rankine cycle (ORC) is one of the most potential low-grade thermal-power conversion technologies, and the selection of design conditions and the system design and operation method considering variable conditions are of great significance for reducing the annual power generation cost or improving the annual power generation efficiency of the system. A synchronous optimization model of equipment structure parameters and system operation parameters of waste heat driven ORC system is established and a solution strategy proposed. Considering the characteristics of ambient temperature changing with seasons, four environmental temperatures are selected as the design conditions, the optimal design scheme is obtained respectively, based on the four design structures, while the annual operation scheme optimized, and the synthesis of annual variable conditions under different system configurations compared. The results show that it is important to optimize the system parameters and equipment structure parameters simultaneously to improve the system performance. With different environmental design temperatures, the optimal design structure and operation scheme are different. The system can be optimized according to the environmental temperature of multiple variable working conditions to optimize the annual operation scheme.

Key words: waste heat recovery, organic Rankine cycle, off-design, annual performance of the system
