Abstract

The invention provides a wind power curve multi-target comprehensive evaluation method and device and a server, and relates to the technical field of wind power plant data processing. The method comprises: obtaining actually-measured data samples, and the actually-measured data samples being actually-measured operation data of the wind speed and power of a draught fan in a wind power plant withina specified time period; drawing a wind power curve of the fan in a specified time period according to the actual measurement data sample; wherein the wind power curve is a curve based on wind speed and power; establishing an evaluation model based on the wind power curve, and calculating evaluation indexes corresponding to the evaluation model; and performing multi-target comprehensive evaluationon the wind power curve according to the evaluation indexes. The invention provides a wind power curve multi-target comprehensive evaluation method and device and a server. According to the method, multi-target comprehensive evaluation can be carried out on the wind power curve according to the evaluation indexes, then quantitative evaluation is carried out on the comprehensive performance of thewind power curve, the comprehensive evaluation problem of the performance of the wind power curve is well solved, and a solid foundation is laid for subsequent data analysis.

Description

technical field [0001] The invention relates to the technical field of wind farm data processing, in particular to a multi-objective comprehensive evaluation method, device and server for wind power curves. Background technique [0002] The wind power curve is an important characterization of the output characteristics of wind turbines and wind farms. It is useful for the estimation and prediction of the theoretical power generation of wind turbines and wind farms, the evaluation of wind power operation performance, the monitoring of wind power operation status and fault diagnosis, and the optimal dispatch of wind farms. important meaning. Therefore, obtaining high-fidelity wind power curves is an important focus of current academic and industrial circles. [0003] Based on actual operating data, many different wind power curve modeling methods have been studied. However, effective evaluation methods for wind power curve performance have not received sufficient attention. ...
