Solution Overview

Problem

Current wind power plant management systems lack effective fault prediction and maintenance planning, which can lead to unexpected failures and reduced energy generation reliability.

Innovation Solution

A wind power plant management system that collects work environment data, compares it to a predefined normal state model to predict faults, estimates the time until a fault occurs, and establishes a maintenance plan, including automatic control and resource allocation to prevent or address faults before they happen.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If fault prediction and maintenance planning systems are implemented in wind power plants, then reliability of power generation is improved, but device complexity increases

Engineering Contradiction:
Improvepower generation reliabilityVSAvoidmanagement system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The management system is divided into distinct functional modules: a data collection unit that gathers work environment data from sensors, a fault occurrence prediction unit that analyzes the collected data, and a maintenance plan establishment unit that generates maintenance schedules. This segmentation allows each module to perform its specific function independently, improving reliability through specialized processing while managing complexity through modular design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system performs preliminary fault prediction by continuously analyzing work environment data before actual faults occur. The fault occurrence prediction unit processes sensor data to identify potential issues in advance, and the maintenance plan establishment unit prepares maintenance schedules proactively. This preliminary action prevents unexpected failures, thereby improving power generation reliability.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If continuous monitoring and fault prediction are performed, then power generation suspension is reduced, but loss of time for data processing increases

Engineering Contradiction:
Improvecontinuous operation capabilityVSAvoiddata processing time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The fault occurrence prediction unit focuses on analyzing only the critical work environment data parameters that are most indicative of potential faults, rather than processing all possible data equally. This partial action approach identifies the most relevant data points for prediction, reducing overall data processing time while maintaining the ability to detect faults that would cause power generation suspensions.

Inventive Principle:
Principle #16Partial or excessive action

3Productivity

If maintenance plans are established based on predicted fault occurrence time, then productivity is improved by preventing failures, but loss of time for planning and scheduling increases

Engineering Contradiction:
Improveenergy generation efficiencyVSAvoidmaintenance planning time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The maintenance plan establishment unit creates maintenance schedules in advance based on predicted fault occurrence times from the fault occurrence prediction unit. By performing this planning action preliminarily, the system prevents unexpected failures that would disrupt power generation and reduce productivity. The automated scheduling process minimizes the time required for manual planning while ensuring maintenance is performed at optimal intervals.

Inventive Principle:
Principle #10Preliminary action
