Beschreibung
Zusammenfassung:	The invention discloses a large wind power blade internal circulation fan heater device. The large wind power blade internal circulation fan heater device comprises an icing diagnosis unit and a heating and deicing unit, wherein the icing diagnosis unit comprises a main controller and a programmable controller; the heating and deicing unit is connected with the icing diagnosis unit through a control processor and comprises a fan heater; and when the actually measured power of the icing diagnosis unit in the diagnosis period is lower than the estimated power, the icing diagnosis unit gives a fault alarm and starts the heating and deicing unit. According to the large wind power blade internal circulation fan heater device, the heating and deicing unit is arranged in blades of a wind turbine generator, and when the icing diagnosis unit diagnoses the icing state, the heating and deicing unit can be started for heating and deicing, so that ice covering the surfaces of the blades is gradually melted under the actio
