Abstract
A solar-aided coal-fired flexible power generation system and an operating method thereof are provided. The system includes a coal-fired thermal power generation system and a high-temperature heat storage system coupled with solar thermal power generation; wherein a heat storage medium heater is arranged in the boiler flue; the flow rates of heat storage medium entering the solar heat collection device and the heat storage medium heater are adjusted by the regulating valve and the pump, eliminating irradiation fluctuation influences and maintaining stable power; a heat storage medium tank is used for peak shaving to reduce steam turbine output under stable boiler combustion; the flow and temperature of the feedwater entering the heat storage medium and feedwater heat exchanger are adjusted to realize rapid load cycling. The present invention can realize solar and coal-fired generation coupling, reduce coal consumption, and greatly improve the flexibility and economy.
