Study on Dynamic Performance and Control Strategy of Solar Energy Adied Combined Cycle Complementary System Under Cogeneration Operation
Cogeneration technology can not only supply industrial steam and civil heating,but also im-prove the energy utilization efficiency of power plant.In this paper,the dynamic model of solar adied combined gas and steam cycle system is established,and the corresponding operation control strategy is proposed.On this basis,the dynamic characteristics of the system under typical operating condition are analyzed.The results show that the system operating parameters,such as main steam parameters,heating power and generating power are remain relatively stable when the solar irradiation fluctuates.The thermal efficiency of the system is between 55%and 63%,and is inversely proportional to the heat input of solar energy in the system.In addition,the solar power generation and heating capacity in the system are 114.96 MWh and 5.3×105 GJ,respectively.
