Abstract
A system and method are provided for monitoring trash rack fouling in a turbine facility. The trash rack monitoring system includes sensors for detecting apparent gross head, flow rate, and effective gross head. The head values are used to select performance curves representative of historical turbine operation at the two head values. The two performance curves are simultaneously displayed on a computer monitor to graphically depict the decreased turbine performance resulting from fouling of the trash racks. The performance is also shown as an economic loss value. A method is also provided for optimizing performance in a multi-unit turbine facility. The method involves determining the net head on each turbine unit as a basis for selecting net head performance curves and ultimately deriving an optimum operating point for each turbine unit.
