摘要

为实现燃煤电厂(CFPP)与压缩空气储能(CAES)的高效耦合，提出了一种CFPP烟气侧与CAES耦合的系统。该耦合系统释能阶段利用CFPP烟气加热进入膨胀机前的高压空气，避免了引入额外的热源增加成本或从汽轮机侧抽取蒸汽加热高压空气影响火电机组出力。随后为减小引出烟气对单台火电机组运行的影响，建立共享2台火电机组烟气的CAES耦合系统。基于以上系统热力学模型，通过EBSILON软件建模并进行性能分析，提出厂级耦合系统经济性最优运行策略。结果表明：满负荷时烟气耦合方案相对于蒸汽耦合方案标准煤耗率降低2.15 g/(kW·h)，热耗率增加37.06 kJ/(kW·h)，能量利用系数提升0.33百分点，厂用电率下降0.20百分点；烟气侧耦合的总电效率、往返效率和CAES运行效率都高于蒸汽侧耦合方式；厂级耦合系统在经济性优化后，4个典型日的净收益较原始机组分别上涨了14.37万元、15.76万元、18.81万元和20.87万元。

Abstract

To achieve efficient coupling between coal-fired power plants(CFPP) and compressed air energy storage(CAES)

a system that couples the flue-gas side of CFPP with CAES is proposed. During the energy release phase of this coupled system

the flue gas from CFPP is used to heat the high-pressure air before it enters the expander. This avoids introducing additional heat sources

which would increase costs

or extracting steam from the turbine side to heat the high-pressure air

which would affect the output of the thermal power unit.Subsequently

to reduce the effect of extracted flue gas on the operation of a single thermal power unit

a CAES coupled system sharing the flue gas of two thermal power units is established. Based on the above thermodynamic models of the systems

modeling is carried out using EBSILON software and performance analysis is conducted.Then

an optimal economic operation strategy for the plant-level coupled system is proposed. The results show that

at full load

compared with the steam-coupling scheme

the flue-gas-coupling scheme reduces the standard coal consumption rate by 2.15 g/(kW·h)

increases the heat consumption rate by 37.06 k J/(kW·h)

raises the energy utilization coefficient by 0.33 percentage point

and decreases the auxiliary power rate by 0.20 percentage point. The overall electrical efficiency

round-trip efficiency

and CAES operating efficiency of the flue-gas-side coupling are all higher than those of the steam-side coupling. After the economic optimization of the plant-level coupled system

the net revenues of four typical days increase by 143 700

157 600

188 100 and 208 700 yuan

respectively.
