A statistical method and deicing system for wind power generation

Abstract

The present invention provides a statistical method and deicing system for increasing power generation of a fan. The fan includes a generator host, a control processor, and a heating device. The heating device is used for deicing the blades of the fan. When the icing period state is switched to the icing period state, it is determined that the icing period of the fan starts, and the non-icing period state and the icing period state are two working states of the fan; internally acquire the real-time power generation of the fan and the real-time power consumption of the heating device; calculate the real-time additional power generation of the fan during the freezing period according to the real-time power generation and the real-time power consumption. The wind turbine generating capacity statistics method and the deicing system provided by the present invention can accurately count the total generating capacity of the wind turbine in the period of icing period, which helps to accurately understand the income of the wind turbine under different working conditions, and is conducive to optimizing the wind turbine The operation strategy can improve the operating efficiency of the wind turbine during the icing period.

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...
