PHYSICS-BASED DIGITAL TWIN FOR HYDRO POWER PLANT TRANSIENT MONITORING
Digital Twin of Hydroelectric Power Plant
Real Time Water Hammer/Surge Tank/Unit Transient Monitoring
Features
- Detection of Abnormal Pressure Transients prior to Reach Admissible Limit
- Detection of Anomalies
- Monitoring of Non Measurable Quantities
- Deviation of Hydropower Physical Characteristics
- Ahead of Time Projections of the State of the System (Decision Support Tool, Alert Awareness, What if…?)
- Anticipation of Potential Power Plant Damage
- Penstock Fatigue Monitoring
Alarm system
Type 1: Exceedance of the admissible limit of a measured quantity
Type 2: Exceedance of the admissible limit of a non measurable quantity
Type 3: Divergence measurements/simulations
Hydro-Clone comprises:
A calibrated SIMSEN model of the HPP, operated in Real-Time and using in-situ measured boundary conditions including:
- hydraulic circuit: galleries, surge tanks, valves, pressure shaft, pumps and turbines (Pelton, Francis, Pump-Turbine, Kaplan)
- mechanical inertia and coupling shaft
- electrical system: motor-generator, transformer, circuit breakers, transmission lines
A real-time monitoring system performing the following tasks:
- Real-Time acquisition and transfer of in-situ measured boundary conditions and quantities to SIMSEN model
- data processing and diagnosis of the power plant health
- provide pre-defined appropriate alarms based on both real-time (RTSM) and ahead-of-time (ATSM) analysis
- communication with archival storage system
A tailor-made archival storage and related database system enabling:
- to archive simulated and measured quantities
- to display and analyse previous results
- to contingence alarms
- to update and enhance the clone functioning

Purposes
Real-time Water Hammer/Surge Tank/Unit transient Survey
Detection of abnormal pressure transients prior to reach admissible limit:
- Significant deviation between measurement and simulation
- Identification of unappropriated sequence settings
- Identification of possible hydroacoustic resonances
Detection of anomalies:
- Air admission
- Unexpected valve closure
- Flow obstruction by external body
- Water column separation
- Transducer failure/dysfunction
Monitoring of non-measurable quantities:
- Pressure and discharge in headrace/tailrace tunnels
- Pressure and discharge along the penstock
- Torque, current and voltages
Deviation of hydropower physical characteristics:
- Head losses increase
- Turbine/generator efficiency drop
- Closing law drift
- Ahead-of-time projections of the state of the system
- (Decision Support tool, Alert Awareness, what-if…?)
Anticipation of potential power plant damage:
- Fatigue evaluation
- Buckling risk
