Abstract

The present invention provides a wind power curve multi-objective comprehensive evaluation method, device and server, and relates to the technical field of wind farm data processing. The actual measured operation data of wind speed and power of the fan; draw the wind power curve of the fan within a specified time period according to the measured data sample; where, the wind power curve is a curve based on wind speed and power; establish an evaluation model based on the wind power curve, and calculate the corresponding evaluation model The evaluation index; according to the evaluation index, the multi-objective comprehensive evaluation of the wind power curve is carried out. The wind power curve multi-objective comprehensive evaluation method, device and server provided by the present invention can carry out multi-objective comprehensive evaluation on the wind power curve according to the evaluation index, and then perform quantitative evaluation on the comprehensive performance of the wind power curve, which better solves the problem of wind power. The problem of comprehensive evaluation of curve performance has laid a solid foundation 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 investigated. However, effective evaluation methods for wind power curve performance have not received sufficient attent...
