Wind Farm Parkmaster Control for Flexible Grid-State Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wind farm control systems lack flexibility and adaptability, as they are often designed as integrated units, limiting their ability to efficiently manage and adjust electrical states at the transfer point, which can impact the overall performance and integration with the grid.
Innovation Solution
The system divides the higher-level control level into two functional units: a sensor station for measuring and transmitting data on the electrical state at the transfer point, and a Parkmaster module integrated into wind farm components, allowing for flexible control specification determination and distribution across multiple wind turbines and components, including reactive power compensation and transformer management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the higher-level control is designed as an integrated unit (Parkmaster), then the control system is simpler to implement, but the flexibility and adaptability of the control system deteriorates
Solution Approach 1:
The higher-level control is segmented into two functional units: a sensor station for data acquisition and a Parkmaster module for control specification determination. This segmentation allows the control system to maintain simplicity in implementation while improving flexibility, as each unit can be independently configured and adapted to different operational requirements.
2Ease of operation
If control specifications are centralized in a single Parkmaster unit, then the control logic is easier to manage, but the system's ability to efficiently manage and adjust electrical states at the transfer point deteriorates
Solution Approach 1:
The control functions are segmented between the sensor station and Parkmaster module, with the sensor station handling data acquisition and the Parkmaster module handling control specification determination. This segmentation improves electrical state adjustment efficiency by allowing parallel processing of sensor data and control calculations, while the control logic remains manageable through clear functional separation.
Solution Approach 2:
The sensor station acts as an intermediary between the physical measurement environment and the Parkmaster module's control logic. It collects sensor data about the electrical state at the transfer point and transmits this data to the Parkmaster module, enabling efficient and accurate control adjustments without complicating the overall control logic management.
3Measurement precision
If the sensor station and Parkmaster module are spatially separated, then the measurement of electrical state at the transfer point is more accurate, but the system complexity increases
Solution Approach 1:
The system is segmented into a sensor station positioned at the transfer point for accurate electrical state measurement and a Parkmaster module that can be located elsewhere in the wind farm. This spatial segmentation improves measurement precision by placing sensors directly at the measurement point while managing system complexity through defined communication interfaces and data transmission protocols between the separated components.

AI summary
A method for controlling a wind farm, in which control commands (30) for a plurality of wind farm components (14, 15, 16) are issued at a higher-level control level (20, 25). Sensor data are acquired in a sensor station (20) assigned to the higher-level control level (20, 25). The sensor data are transmitted to a wind farm component (14, 15, 16). The sensor data are processed in a park master module (25) of the wind farm component (14, 15, 16) to determine control commands (30) for the plurality of wind farm components (14, 15, 16). The invention also relates to a wind farm control system with which the method can be carried out. Such a control system can be used and adapted flexibly.
