Description

Apparatus and method for controlling wind power generation The present invention relates to a wind power generation control device and method, as a technology for controlling wind power generators, which can increase power generation efficiency by controlling the turbine direction of the wind generator according to the wind direction. Offshore wind power technology is a system that converts the kinetic energy of wind into electricity using wind turbines installed in the sea. To achieve large-scale power generation, the primary method utilized involves installing turbines in shallow waters near the coastline. These turbines are stationary structures directly connected to the seabed and operate by optimizing power efficiency through adjustments to their rotational speed based on wind direction and speed. However, as changes in the marine environment and weather conditions can make efficient energy production difficult, supplementary technologies such as turbine direction control and wind forecasting systems have been required. Korean Patent No. 10-2425267 discloses features of a control device and method for a digital twin-based offshore wind farm.

FIGS. 2 and FIGS. 3 are exemplary diagrams for explaining a method of controlling the direction of a wind turbine according to one embodiment.

In describing the present invention, if it is determined that a detailed description of related known functions or configurations may unnecessarily obscure the essence of the present invention, such detailed description will be omitted. Furthermore, the terms described below are defined considering their functions in the present invention, and these may vary depending on the intentions or conventions of the user or operator.

Referring to FIG. 1, a wind power generation control device (100) may include a driving unit (110) including an actuator that changes the direction in which a wind turbine is facing, a sensor unit (120) including a sensor that measures at least one of wind direction, wind speed, rotation direction of the wind turbine, rotation angle, rotation speed, and actuator driving power, and a control unit (130) that generates a direction control signal based on at least one of weather forecast information received from the outside and sensor information generated by the sensor unit (120), and transmits the direction control signal to the driving unit (110) to change the direction in which the wind turbine is facing. For example, a wind power generator may be a system in which multiple wind turbines are installed in a specific area of the sea, and each wind turbine may be equipped with a direction-controlling actuator and various sensors. The actuator controls the turbine's propeller to rotate in the optimal direction to generate power, while the sensors can detect information related to the turbine's operation in real time, such as wind direction, wind speed, and the status of the actuator. The wind power generation control device (100) visualizes data collected from sensors installed on each wind turbine based on digital twin technology, and allows the user to monitor the status of the turbine and support maintenance. The wind power generation control device (100) can adjust the direction of the turbine automatically or according to the user's command, and the user can receive support for decision-making based on the direction of the controlled turbine, power generation amount, optimal rotation direction, and predicted power generation amount information.

Through this, the control unit (130) can adjust the direction of individual wind turbines according to the direction change control command and predict the amount of power generated accordingly. For example, the control unit (130) receives weather data such as wind direction, wind s
