摘要

Due to the complexities of the California energy markets, a financial model to look at the lost revenue of a no-run zone was not able to be constructed until more market data are gathered under non-restricted operations. These data will be collected once units are returned to unrestricted operation. What did evolve from this project was a standardized method of looking at draft tube issues as they relate to rough operating zones or no-run zones. Each unit is looked at individually, from the design of the draft tube to the operating conditions under which they generate. Tests are then designed to collect data and measure spe- cific parameters (i.e., pressure, vibration, strain) and evaluated for short-term failure or more long-term failure from fatigue. FEA has proved to be invaluable for determining resonant frequencies and high-stress areas and evaluating potential design changes. Data collected on units removed from the no-run zone may help construct financial models to evaluate lost revenue.
