In order to optimize the heat supply scheme for coupled system of wind power and condensing units

the simulation model of a 350 MW extraction condensing unit was established by Ebsilon software

and the functional relationship between the main steam consumption of the condensing unit and the electric/heat load was obtained.Parameters such as the absorbing wind power capacity

main steam consumption and heat load expansion ratio under the original steam extraction heating scheme and other four heating schemes(including adding heat storage tank

adding heat storage electric boiler

adding electric heat pump and heat storage tank coupling devices

and adding absorption heat pump) were calculated. The results show that

compared with the original extraction steam heating scheme

the other four heating schemes can further improve the condensing unit's capacity that be affected by specific limiting factors to absorb wind power. The order of reducing the consumption of main steam from large to small is

adding the coupling device of electric heat pump and heat storage tank

adding the heat storage electric boiler

adding the absorption heat pump

and adding the heat storage tank. The order of the heat load expansion ratio from large to small is

adding the coupling device of electric heat pump and heat storage tank

adding the heat storage electric boiler

adding the heat storage tank

and adding the absorption heat pump.
