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
