Embodiment 1

[0047] The output performance of wind turbines in a wind farm in Anhui is poor, and the wind farm needs to evaluate the power curve of the wind turbines in the whole field. Since the wind farm has 30 wind turbines, if a wind measuring tower is built to test and evaluate the wind turbines in the whole field, the construction cost is huge, the test period is long, and it will bring troubles to the daily maintenance of the wind farm.

Abstract

The invention relates to a wind turbine generator set power curve testing method based on a SCADA (supervisory control and data acquisition) system. The method is based on related data such as wind speeds and generator rotating speeds acquired by the SCADA system of a wind power plant and records such as faults and machine halt and comprises the following steps of: carrying out data reduction and analytical calculation by using SCADA big data of a wind turbine generator set to obtain actual measured power curves of the wind turbine generator sets in the whole plant; and comparing the actual measured power curves of the wind turbine generator sets in the whole plant with guaranteed power curves during set bidding, thereby guiding operation, overhauling and out-of-warranty management of the wind power plant and improving the electric energy production of the wind turbine generator set in the whole plant.

Description

technical field [0001] The invention relates to a method for testing the power curve of a wind turbine, in particular to a method for testing the power curve of a wind turbine based on a SCADA system. Background technique [0002] The power curve of the wind turbine is the relationship curve between the output power of the wind turbine and the wind speed, and is an important indicator used to measure the output performance of the wind turbine. Usually, there is a difference between the guaranteed power curve provided by the wind turbine manufacturer and the power curve generated during the actual operation of the wind turbine. If the actual power curve is higher than the guaranteed value, the unit may be in a state of fatigue for a long time, resulting in a shorter service life of the unit; if the actual power curve is lower than the guaranteed value, the generating capacity of the unit will decrease. Therefore, it is necessary to test the power curve of the wind turbine. ...
