Improving Unit Startups through Control Loop Performance Monitoring

This project evaluated the ability of control loop performance monitoring (CLPM) technology to both identify and characterize issues that impede the efficiency of plant operations during startup. In particular, the project focused on quantifying the effects of control loop tuning, mechanical, and loop interaction issues on startup efficiency. Analysis was conducted on a 550-Megawatt combined cycle gas-fired unit from June 15, 2018 to October 4, 2018. It included analysis of data from the facility’s startup and normal runtime operations.
