Problems solved by technology

However, because fans of different brands and models have different performances and working conditions are not the same, there is no unified testing technology that can achieve a unified performance measurement for fans of different brands and models, and it is impossible to test different models of different brands. Comparing the performance of different wind turbines is not conducive to the deployment and implementation of wind turbine generator sets by grid personnel to obtain the maximum power generation efficiency

Embodiment 1

[0033] Embodiment 1 of the present invention: a method for measuring fan performance based on a standard wind speed-power curve, such as figure 1 As shown, including the following steps:

[0034] S1, collect multiple sets of wind speed-output power data of multiple different fans;

[0035] S2, constructing a wind speed power curve of each wind turbine according to the multiple sets of wind speed-output power data;

[0036] S3: Fit the wind speed power curve of each wind turbine to a standard wind speed-power curve; specifically including the following steps:

[0037] (1) Assuming that the rated power coefficient corresponding to the rated power of each fan is 10, the rated wind speed coefficient corresponding to the rated wind speed is 10; the cut-in wind speed coefficient corresponding to the cut-in wind speed of each fan is 3, and the corresponding minimum power corresponds to the minimum The power factor is 0.06;

[0038] (2) Calculate the wind speed coefficient-power coefficient co...

Abstract

The invention discloses a fan performance determination method based on a standard wind speed-power curve. The method comprises the following steps: (S1) multiple sets of wind speed-output power data of multiple different fans are acquired; (S2) wind speed-power curves of all the fans are built according to the multiple sets of wind speed-output power data; (S3) the wind speed-power curves of all the fans are formed to the standard wind speed-power curve; and (S4) the performance determination of all the fans is realized according to the standard wind speed-power curve. As the wind speed-power curves of all the fans are formed to the standard wind speed-power curve, the method can realize the unified determination and comparison of performances of the fans with different brands and model numbers so as to facilitate a generator set to obtain the maximum power generation efficiency.

Description

Technical field [0001] The invention relates to a method for measuring the performance of a fan based on a standard wind speed-power curve, and belongs to the technical field of wind power generation. Background technique [0002] The wind turbine is an important part of the wind turbine. The performance of the wind turbine is related to whether the entire unit can operate safely and economically. Generally speaking, each type of wind turbine will give a wind speed-power curve correspondence table to intuitively describe the relationship between wind power output and wind speed. However, because different brands and models of fans have different performance and working conditions are not the same, there is currently no unified testing technology that can achieve a unified performance measurement for different brands and models of fans, and it is impossible to measure different brands and models. Comparing the performance of the wind turbines is not conducive to the deployment an...
