Research on the Operation of Electric Boiler Assisting Gas-steam Combined Cycle Unit

In recent years, due to the increasingly prominent contradiction between cogeneration unit heating and grid peak regulation and wind power consumption in the heating season, the grid peak regulation situation is severe, and the traditional operation mode of “fixing electricity by heat” needs to be transformed to the mode of “cogeneration”. It is worth studying that the gas-steam combined cycle heating unit can continue to provide a certain heat load after participating in the power grid peak regulation. This paper mainly studies how to use electric boilers to assist the operation of gas-steam combined cycle units in heating period, in order to enhance the peak load capacity and heating capacity of gas-steam combined cycle unit. And it can heat the air entering the compression room by the circulating water from heat supply network produced by electric boiler, so as to improve the working efficiency of gas-steam combined cycle units.
