Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings. It should be understood that the content described here is only for illustration and explanation of the present invention, and is not intended to limit the present invention.

[0017] To optimize the wind deviation of the selected units, the optimization process is as follows: figure 1 As shown, including data analysis, control program algorithm adjustment, safety check and effect verification.

[0018] 1. Data analysis

[0019] First of all, it is necessary to analyze the data of the candidate optimized units to determine the angle data of the windward deviation.

[0020] 1.1 For data analysis, implement statistical analysis methods for historical data. First, normal statistics are performed on the wind angle data of the actual unit. The center line of the actual wind angle data distribution point has a certain deviation, such as about 10°, but not near 0°. Correct t...

Abstract

The invention discloses a method for correcting and optimizing wind deviation of a wind generating set. The method for correcting and optimizing wind deviation of the wind generating set comprises the following steps that S1, historical data statistics is conducted on a to-be-optimized set, and wind angle data correction is conducted on the set; historical working data of a fan are extracted; S2, data analysis is conducted; working condition identification, working condition screening, power distribution calculation, optimization and derivation self-inspection processes are automatically carried out; S3, a control program is updated; S4, security check is conducted according to a modification result; S5, operating data within a certain time are collected, and effect verification is carried out on the optimized unit; the actual wind deviation value of the fan is obtained through statistical analysis, and control program compensation is adjusted, so that accurate wind of the fan is achieved, the power generation performance of the fan is improved, and the extra load is reduced; data analysis and optimization are automatically carried out, safety verification is executed, the fan data optimization speed is increased, and fan optimization is guaranteed to be safe and reliable.

Description

technical field [0001] The invention relates to the technical field of wind farm operation control, in particular to a method for correcting and optimizing the wind deviation of a wind power generating set. Background technique [0002] At present, the early domestic wind farms have been put into operation for more than 10 years. The electric control system of the unit, especially the measurement and wind system of the unit has been operating in a harsh environment for a long time. , resulting in the loss of generating capacity of the unit. Some testing institutions and laboratories in the world have tested the yaw-to-wind error of wind turbines, and analyzed the influence on wind energy absorption of wind turbines in the presence of yaw-to-wind errors. Among them, the unit runs for a long time and detects the error itself, reflecting that the power loss is proportional to the square of the cosine of the error angle. Through the investigation and analysis of the actual ear...
