Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation of fan-stopping devices is used, then the system can be simple and cost-effective, but safety problems arise and operation convenience deteriorates
Solution Approach 1:
The control system automatically monitors wind speed and rotational speed, and autonomously adjusts the fan-stopping device without requiring technician intervention. The system serves itself by detecting noise conditions and automatically implementing control actions, eliminating the need for manual operation while maintaining safety.
Solution Approach 2:
The system incorporates feedback mechanisms where wind speed sensors and rotational speed sensors continuously monitor system parameters and feed this information to the control unit. Based on this feedback, the control unit automatically adjusts the fan-stopping device to maintain safe operating conditions, ensuring both convenience and safety through automated closed-loop control.
2Reliability
If automatic control system is implemented, then safety and operation convenience are improved, but system cost increases
Solution Approach 1:
The control system integrates multiple functions into a single unified platform: wind speed monitoring, rotational speed monitoring, noise detection, automatic fan-stopping device control, and data logging. By making the system multi-functional, the patent reduces overall system complexity and cost compared to having separate dedicated devices for each function.
Solution Approach 2:
The patent combines the control unit, wind speed sensor, rotational speed sensor, and fan-stopping device control into an integrated system. Rather than using separate independent devices, the control functions are merged into a single control system that manages all aspects of wind turbine operation, reducing total system cost and complexity.
3Device complexity
If rule establishment is incomplete due to user unfamiliarity, then system complexity is reduced, but control effectiveness deteriorates
Solution Approach 1:
The system automatically generates control rules based on real-time monitoring of wind speed and rotational speed relationships. Rather than requiring users to manually establish control rules, the system self-adjusts by analyzing operational data and automatically optimizing control parameters, ensuring effective control without increasing user complexity burden.
Solution Approach 2:
The control system continuously monitors the relationship between wind speed and rotational speed, and uses this feedback to automatically refine and update control rules. The system learns from operational data and automatically adjusts control strategies to maintain optimal performance, ensuring control effectiveness without requiring complex user input.

AI summary
A wind turbine control system includes a wind turbine, a power-converting device connected with the wind turbine, a control device and a human-machine interface. The control device is connected with the power-converting device. The control device includes a storage module having a first database, among which a first control data is stored in the first database. The human-machine interface having a GUI is connected with the control device. A second control data is set through the GUI and stored in the first database, such that the wind turbine is automatically controlled to rotate at a first rotational speed in a first time period and rotate at a second rotational speed in a second time period by the control device according to the first control data and the second control data. Therefore, the safety concerns are reduced, the operations are simplified, and the probable of inputting improper control parameters is eliminated.
