For the problem of the abandoned large-scale wind power currently, in order to improve the utilization of wind power and make full use of wind resources, a method of using wind power to heat the condensed water through electrothermal furnace is proposed. On the basis of mass and energy conservation, through analyzing variable condition of the regenerative heating system and water-cooled condenser, the dynamic mathematical model is created and then the dynamic influence of condensed water temperature on the economy of thermal power plant is studied. This paper, taking a typical 660MW water-cooled unit as an example, discusses the dynamic characteristics of steam turbine and energy-saving effects of this method. Results show that obvious economic effects can be obtained through non-grid-connected wind power heating the low-pressure condensed water, which can reduce the steam extraction flow from steam turbine, improve the thermal efficiency of thermal power plant and save the amount of coal. It has positive significance to digging energy-saving potential of plant.
