【 摘 要 】

Due to a large number of new energy power generation, the contradiction of heat-electricity is prominent in the period of winter in north China. In order to effectively eliminate the renewable energy power generation and promote the healthy development of the electric power industry in China, it is urgent to improve the peak load capacity of cogeneration unit. In this paper, a new method of thermoelectric decoupling was proposed for traditional coal-fired power generation unit, which was the transformation of thermoelectric decoupling system of integrated absorption heat pump. The comparison tests before and after the transformation of the absorption heat pump was carried out for a pilot unit. Then, the thermal power decoupling capability, energy saving benefit and special advantages of this method were analysed. The result showed that this method can both improve the energy-saving and thermoelectric decoupling. Furthermore, it also can improve the thermal efficiency of the unit and maintain the characteristics of safe and stable operation and responsive of the power load.
