Abstract

The invention discloses a wind turbine generator power characteristic testing method under a complex terrain. The wind turbine generator power characteristic testing method comprises the following steps of: step 1, selecting one wind turbine generator A with the same type as a wind turbine generator B to be detected, wherein a surrounding field of the wind turbine generator A can pass through field assessment conditions in the IEC (International Electro-technical Commission)-61400-12-1; step 2, synchronously recording a wind speed Vfront in front of a wind wheel of the wind turbine generator A and a wind speed Vback behind the wind wheel of the wind turbine generator A for multiple times; step 3, carrying out linear fitting on the Vfront and the Vback, and recording as a formula Vfront=aVback+b; step 4, synchronously recording a wind speed Vback behind a wind wheel of the wind turbine generator B and an outlet pure power P for multiple times; step 5. calculating the wind speed Vfront in front of the wind wheel of the wind turbine generator B by utilizing that Vfront=aVback+b and the Vback in the step 4; and step 6, calculating a power characteristic of the wind turbine generator B by using the outlet pure power P of the wind turbine generator B and the Vfront. The testing method provided by the invention can be applied under condition the condition that the field assessment is unqualified, and the testing cost is low.

Description

technical field [0001] The invention relates to the field of type certification of wind turbines, in particular to a method for testing power characteristic curves of wind turbines under complex terrain. Background technique [0002] IEC standard: IEC61400-12-1:2005 "Wind Turbine Generator Power Characteristics Test" specifies in detail the method for testing the power characteristics of a single wind turbine, which is used to test the power generation capacity of the wind turbine. This method is applicable to grid-connected wind turbines of all types and capacities. This unified approach can ensure the consistency, accuracy and repeatability of wind turbine power characteristic testing and analysis. The power characteristic test of wind turbines can confirm that the new or repaired wind turbines purchased by the wind turbine operator meet the technical conditions of the power characteristics stated by the wind turbine manufacturer. Fair, clear and objective evaluation of ...
