Abstract

The invention discloses a blower fan load high-efficiency assessment system. The blower fan load high-efficiency assessment system includes a querying module of a load simulation database, wherein the querying module can query and manage simulation input data and load data of all types of research and development machines, such as a unit boundary condition, tower size, blade design data, a complete machine Bladed model, and load data of main parts, blades, and a tower; a load comparison and sensitivity analysis module which can perform comparison analysis on boundary conditions, main part loads, and blade and tower loads of different projects, and perform sensitivity analysis on loads of identical projects with different boundary conditions; and a unit load strength applicability assessment module which can interpolation-calculate a load corresponding to a specific site based on mass load simulation data change for boundary condition parameters such as the air density, the annual average wind speed, the turbulence intensity, wind shear, and the inflow angle, and can perform strength assessment on parts according to strength assessment margin of a reference project. The blower fan load high-efficiency assessment system can improve the calculation efficiency of a blower fan generator unit load, can shorten the life period, and can save cost.

Description

technical field [0001] The invention relates to the field of load calculation of wind power generating sets, in particular to a high-efficiency wind load evaluation system. Background technique [0002] In the design of wind turbines and the construction of wind farms, the load calculation of wind turbines is a very important link. The load of a wind turbine refers to the force or moment that the external environment and the internal environment act on its components, including aerodynamic loads, gravity loads, inertial loads, and operating loads caused by control system actions. According to the classification of structural design requirements, the load of wind turbines can also be divided into ultimate load and fatigue load. The ultimate load refers to the maximum load that the wind turbine can bear, and the fatigue load refers to the alternating cycle load acting on the wind turbine. The purpose of wind turbine load analysis and calculation is to calculate the stress an...
