Problems solved by technology

However, the actual operating conditions of the fan are extremely complex, and its components are prone to wear and failure under the influence of the environment.
If the damaged parts are not found and replaced in time, serious safety accidents may occur in the wind turbine, resulting in major economic losses
At the same time, downtime will seriously affect the efficiency of the wind turbine and reduce the economy of the wind farm
[0003] Wind turbines are often affected by various planned and unplanned outages and communication failures on and off the site, resulting in interruption and loss of real-time data transmission, which in turn has a negative impact on wind turbine status monitoring and wind turbine control strategy execution

Abstract

The invention discloses a single-fan virtual wind speed calculation method and system based on wind field wind speed association. The single-fan virtual wind speed calculation method at least comprises the steps of S1, carrying out data acquisition and storage, S2, carrying out data preprocessing, S3, carrying out associated fan selection, and S4, carrying out model training and storage: selecting associated historical data of an associated fan as an input value, inputting the input value into a learning model, and completing training of a wind speed fitting algorithm model; and S5, carrying out virtual wind speed calculation, calling the wind speed fitting algorithm model obtained through training in the step S4 in real time, and obtaining the current wind speed of a target wind turbine through fitting in combination with associated wind turbine associated data. According to the method, under the condition that an anemograph breaks down, auxiliary equipment does not need to be added, and the operation condition of the anemograph can be effectively judged and fitted. The method has the characteristics of simplicity and feasibility, can improve the phenomena of unit abnormity, unplanned shutdown and the like caused by anemograph faults, and improves the power generation efficiency of a unit.

Description

technical field [0001] The invention belongs to the technical field of wind speed forecasting of wind farms, and in particular relates to a method and system for calculating virtual wind speed of a single fan based on wind speed correlation of wind farms. Background technique [0002] In order to achieve carbon neutrality and improve the social environment, wind power has developed rapidly as a clean and green energy. However, the actual operating conditions of the fan are extremely complex, and its components are prone to wear and failure under the influence of the environment. If the damaged parts are not found and replaced in time, serious safety accidents may occur in the wind turbine, resulting in significant economic losses. At the same time, downtime will seriously affect the efficiency of the wind turbine and reduce the economy of the wind farm. [0003] Wind turbines are often affected by various planned and unplanned outages and communication failures inside and ...
