Gas Turbine Performance Monitoring and Predictive Maintenance System

Technology Overview

The technology described herein is related to a performance monitoring and predictive mainenance system particularly for gas turbines in combine cycle power plants. The technology consists of several modules including condition monitoring, Healthcare - Diagonostics, optimal compressor wash, maintenance interval prediction, performance analysis and maintenance economics analysis. The system also enables assessing the performance of gas turbines remotely using a mobile device. This technology has been trialed in a power plant in Korea and the technology provider is keen to reach out to partners for technology collaboration purpose.

Technology Features & Specifications
