Solution Overview
Problem
Wind power installations operated for noise reduction are unable to contribute effectively to stabilizing the electricity supply grid during critical power grid situations, limiting the power grid operator's ability to react to grid instability.
Innovation Solution
A control system for wind power installations and wind farms that includes multiple operating modes and an interface to receive signals from power grid operators, allowing for maximum adjustability and prioritization of power grid stability, enabling the operator to access and control wind farms to stabilize the grid by releasing all operating modes, particularly in critical situations.

Engineering Contradiction Analysis
1Object-affected harmful factors
If the wind power installation is operated in noise-reduction mode with a locked rotational speed above a specific range, then noise emissions are optimized to be below legal limiting values, but the installation cannot contribute effectively to stabilizing the electricity supply grid during critical power grid situations
Solution Approach 1:
The control system dynamically adjusts the rotational speed limits based on operational context. During normal operation, the system maintains noise-reduction mode with locked rotational speed above a specific range. However, upon receiving a signal from the power grid operator indicating critical grid situations, the system dynamically releases the rotational speed lock, allowing the wind power installation to operate at optimal performance speeds for grid stabilization, thus adapting to changing operational requirements.
Solution Approach 2:
The system changes the operational parameters (rotational speed limits) based on external signals. In noise-reduction mode, the rotational speed is constrained to a specific range. When the power grid operator sends a signal indicating critical grid situations, the system changes the parameter by releasing the rotational speed lock, allowing the installation to operate without speed restrictions to maximize power output and contribute to grid stabilization.
2Object-affected harmful factors
If the control system locks the wind power installation above a specific rotational speed range for noise reduction, then noise level is optimized, but the power grid operator has limited ability to react to critical power grid situations
Solution Approach 1:
The control system introduces an intermediary communication interface that allows the power grid operator to send signals to the wind power installation. This intermediary mechanism enables the operator to request release from noise-reduction mode during critical grid situations without directly interfering with normal operational control. The system mediates between the noise-reduction requirement and the operator's need for control by providing a formal signal-based request system.
Solution Approach 2:
The control system dynamically adjusts the rotational speed limits based on operational context. During normal operation, the system maintains noise-reduction mode with locked rotational speed above a specific range. However, upon receiving a signal from the power grid operator indicating critical grid situations, the system dynamically releases the rotational speed lock, allowing the wind power installation to operate at optimal performance speeds for grid stabilization, thus adapting to changing operational requirements.
