Turbine Component Planning Device for Remaining Life Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In some plants, self-inspections are not implemented, leading to inefficiencies in minimizing the remaining life of turbine components, as the technology disclosed in Patent Document 1 may not be effective without changing the timing of self-inspections.
Innovation Solution
A planning device that specifies the remaining life of turbine components and generates a usage plan to ensure the remaining life of each component becomes equal to or less than an allowable error value at a predetermined timing, allowing for efficient use without altering the self-inspection timing, by incorporating components into the turbine such that their remaining life coincides with periodic inspections and calculating the spent life to optimize component replacement.

Engineering Contradiction Analysis
1Productivity
If self-inspection timing is changed to minimize remaining life, then component utilization efficiency is improved, but operational complexity and inspection scheduling difficulty increase
Solution Approach 1:
The system changes the parameter of inspection timing from fixed periodic schedules to dynamic timing based on component remaining life calculations. The planning device calculates optimal replacement timing by considering remaining life, operational hours, and load conditions, then generates usage plans that schedule inspections and replacements at parameters (timing) that maximize component utilization while ensuring safety.
2Reliability
If component replacement is scheduled based on remaining life calculation, then operational safety and efficiency are improved, but the complexity of tracking and managing multiple components increases
Solution Approach 1:
The system implements self-service by automatically calculating remaining life for each component based on operational data, comparing it against thresholds, and generating replacement schedules without manual intervention. The planning device monitors component status, performs life calculations, and produces usage plans autonomously, reducing the need for manual tracking and management while maintaining high reliability through systematic remaining life monitoring.
3Ease of operation
If periodic inspections are maintained without self-inspection, then operational simplicity is preserved, but component remaining life cannot be minimized leading to reduced productivity
Solution Approach 1:
The system performs preliminary actions by calculating remaining life and generating replacement schedules in advance before components actually fail or reach critical thresholds. The planning device proactively monitors component status, predicts remaining life based on operational patterns, and schedules inspections and replacements beforehand, allowing periodic inspections to remain simple while maximizing component utilization through advance planning.
