The invention discloses a wind energy heating unit control method and
system utilizing
waste heat of circulating water of a thermal power
plant. A control method for a wind energy heating unit utilizing
waste heat of circulating water of a thermal power
plant is characterized in that a fan is used for driving a
heat pump to heat the temperature of hot water on a user side after a circulating water
system of the thermal power
plant enters a
heat exchanger, and the hot water is used by a heat user. The flow of cooling water entering the
evaporator is adjusted, and it is guaranteed that the flow meets the heating capacity requirement of the
air heating unit; heat storage or heat release of a heat
storage tank is controlled, specifically, heat storage or heat release is adjusted according to the return
water temperature of a heat user on the basis of
heat balance within a short time, and the change of the return
water temperature of the heat user is stabilized; and controlling the output of the wind-heat unit, wherein the wind-heat unit adjusts the output of the wind-heat unit according to the return
water temperature of the heat user on the basis of
heat balance within a long time. The
system can replace or reduce steam extraction of a thermal power
generating unit, meanwhile, wind energy is used for
heat supply, and
clean energy heat supply is achieved.
