Project Description

The overall objective of this work is the development of model-based sensor placement algorithms for maximizing the robustness and effectiveness of the sensor network to monitor the plant health both at the unit level and at the systems level. This will be achieved by developing a two-tier sensor network algorithm capable of performing component condition monitoring and system-level fault diagnosis. The algorithms will be implemented on a coal-based plant-wide simulation of an Integrated Gasification Combined Cycle (IGCC) with a rigorous gasifier model. The work is also extendable to similar fossil energy plants.

Project Benefits

This project will focus on development of algorithms that will improve the operation and performance of advanced power generating systems. Improvements in robustness and effectiveness of power industry algorithms will lead to higher efficiency power plant opearation, improved grid dispatch, and reduced emissions.
