Predictive Maintenance & Flexible Asset Operations with Digital Hydro Solutions

11 Optimize your Asset Dispatch Within your Plant with Smart Load Dispatch Optimize the dispatching of your units within the plant based on machine design and health conditions in order to minimize the wear and tear or maximize efficiency and optimize maintenance. Increase revenue and reduce failure risk <70s to start a pump turbine from idle to full power (demonstrated on 2x150MWPSP) Optimize the dispatch of your unit based on efficiency, wear, asset health SCADA Speed up the Start-up and Mode Transition with Sequence Booster Improve the starting sequences either to switch from one operating point to another more quickly through enhanced control logics or to reduce turbine damage that can come from speed no load operation during the starting sequence.

If the assessment determines that the range of operation can be extended, GE provides an advanced monitoring & diagnostic system with specialized visualization to monitor the time spent in each of the new operating zones and provides alerts when the operation time in these zones exceeds recommended limits.
