Solution Overview

Problem

Conventional wind power generation systems face challenges in operating optimally under varying site conditions due to environmental factors like wind speed, direction, and humidity, requiring complex and costly controllers specific to each location, which limits their scalability and maintenance efficiency.

Innovation Solution

A multi-class controller that senses environmental conditions and component states to adjust control values, maximizing power generation and reducing component load, allowing universal applicability across various scales and classes without the need for dedicated controllers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional wind power generation systems use dedicated controllers for each location, then the power generation can be optimized for specific site conditions, but the device complexity and development cost increase significantly

Engineering Contradiction:
Improvepower generation optimizationVSAvoidcontroller complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements a universal controller that can adapt to multiple wind power generator types and site conditions through a database storing control parameters for different locations and generator classes. The controller reads appropriate parameters from the database and applies them to optimize power generation without requiring location-specific hardware modifications, thus achieving multi-functionality with a single device.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system optimizes power generation by changing control parameters (such as pitch angle, yaw angle, and generator output) based on environmental conditions and generator state, rather than changing the physical controller itself. The database stores multiple sets of control parameters that can be selected and applied dynamically to match different operating conditions.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If various types of generators are developed for different locations, then the power generation can be adapted to local conditions, but the development time and cost increase due to simultaneous verification requirements

Engineering Contradiction:
Improvelocation adaptationVSAvoiddevelopment time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

Instead of developing and verifying multiple physical generator types for different locations, the patent creates a virtual model of different generator classes and site conditions through a database. The universal controller references pre-stored control parameters that represent optimal settings for various scenarios, eliminating the need for simultaneous physical verification of multiple generator types while maintaining adaptability.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

A single universal controller design can serve multiple generator types and location conditions by accessing the database of control parameters. This eliminates the need to develop separate controller hardware for each location, significantly reducing development time while maintaining the ability to adapt to different environmental conditions.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Reliability

If conventional systems require high-level development and maintenance capability, then optimal power generation can be achieved, but the ease of operation and maintenance decrease

Engineering Contradiction:
Improvepower generation efficiencyVSAvoidmaintenance capability
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The universal controller automatically selects and applies appropriate control parameters from the database based on the generator type and environmental conditions, without requiring operator intervention or specialized knowledge. The system self-adjusts to maintain optimal power generation, reducing the need for highly skilled operators and simplifying maintenance requirements.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The controller continuously monitors environmental conditions and generator state, then automatically adjusts control parameters based on feedback from sensors and the database. This closed-loop control maintains optimal power generation efficiency while reducing the need for manual intervention and specialized maintenance capability.

Inventive Principle:
Principle #23Feedback
