Abstract

The invention provides a fan increased generating capacity statistical method and a deicing system. A fan comprises a power generation host, a control processor and a heating device, wherein the heating device is used for deicing fan blades. The method includes the steps that when the fan is switched from a non-icing period state to an icing period state, it is determined that the icing period of the fan starts, wherein the non-icing period state and the icing period state are two working states of the fan; the real-time generating capacity of the fan and the real-time power consumption of the heating device are obtained within the icing period; and according to the real-time generating capacity and the real-time power consumption, the real-time increased generating capacity of the fan in the icing period is counted. According to the fan increased generating capacity statistical method and the deicing system, accurate statistics can be conducted on the total increased generating capacity of the fan with the icing period as the period, income situations of the fan under different working conditions can be accurately known, operation strategies of the fan can be optimized, and therefore the operation benefit of the fan in the icing period is improved.

Description

technical field [0001] The invention belongs to the technical field of fan power generation, and in particular relates to a method for counting the increased power generation of a fan and a deicing system. Background technique [0002] As one of the important power generation methods that are safe, reliable, pollution-free and can be connected to the grid, wind power has developed rapidly in recent years. In cold and humid areas, fan blades are prone to freezing, which will damage the aerodynamic performance of the blades, reduce the power generation efficiency of the unit, cause accelerated fatigue of components, and reduce service life. In severe cases, the fan will be forced to stop or even collapse, endangering personal safety Therefore, more and more attention has been paid to the icing problem of fan blades, and the heating device for fan blade anti-icing has also been developed rapidly. Existing active deicing technologies for wind turbine blades are mainly divided i...
