Predictive Maintenance & Flexible Asset Operations with Digital Hydro Solutions

9 APR (Advanced Pattern Recognition) - SmartSignal® APR analytics are based on SmartSignal® software which provides early warning notifications of anomalies, along with diagnostics and prioritization. It uses a data driven approach with machine learning algorithms and experts’ rules to define what is normal/abnormal for the hydro assets. A dynamic envelop is created around the normal expected behavior and an alert is triggered when the actual value deviates too much from the projected one. Early Detection - Monitor all signals simultaneously Synchronous shocks in the thrust bearing example Hydro assets design OEM Design Analytics OEM design analytics use highly customized models which require OEM data and that generally focus on predicting the asset remaining useful life. They can be used online as part of APM Reliability to quantify and follow the asset life consumption when powered by the actual operating data. They can also be used off-line as part of a health assessment when fed with the asset historical data. And finally, they can run and test different operating scenarios and verify the impact on the asset lifetime. Highly customized FEA- and CFD-based models Using a GE-defined set of sensors Versatile Self-learning Using available sensors Data driven + experts’ rules High frequency analysis Domain-specific models Self-learning Physics-based and design rules Using GE edge platform and a GE-defined set of sensors Edge Analytics – Hydro Edge Platform Edge analytics are used when real time and fast data acquisition is required (e.g. transient/dynamic phenomena analysis). It requires that the GE Hydro edge platform is installed in the plant to capture and process high frequency data continuously. Smart indicators are created from the raw signals and instantaneously contextualized with operational data, detecting abnormal operations or tracking any asset behavior change over time.
