La gestion des actifs consiste à investir dans la maintenance le plus tard possible afin de maximiser la production, mais avant une défaillance pour assurer la sécurité et éviter de longues indisponibilités. L’utilisation d’un clone numérique permet de prédire le vieillissement des conduites forcées et, ainsi, d’optimiser leur maintenance.

Power Vision Engineering launch HYDRO-CLONE: an Innovative Real-Time Simulation Monitoring (RTSM) System for Hydro Power Plant Transients Survey for:

    • 1) Water Hammer / Surge Tank Survey
    • 2) Real-Time Simulation Monitoring (RTSM)
    • 3) Ahead of Time Simulation Monitoring (ATSM)
    • 4) Detection of Hydraulic / Electrical Anomalies
    • 5) Estimation of Non-Measureable Quantities
    • 6) Anticipation Power Plant Damage (fatigue, buckling)

Simulation of a hydro plant by ‘cloning’ makes it possible to detect undesirable phenomena, such as penstock or gallery overpressures, head loss increases, decreases in efficiency, surge tank limits, start-up and shut-down issues, unexpected cavitation and possible water column separations, air intake, and unwanted valve closures. Furthermore, a clone is able to minimize the risk of potential imminent harmful behaviour of the plant, by generating so-called ‘ahead of-time simulation monitoring’ (ATSM) alarms, based on a series of instantaneous simulations of any potential near-future behaviour of the plant. By combining RTSM and ATSM in real-time, it is believed that the newly developed system, known as Hydro-Clone, can be a valuable numerical asset for hydro plant owners to improve powerplant safety.

Hydro-Clone was presented for teh first time at the International Conference Hydro2015 in Bordeaux, France on October 27, 2015, see below, and was also subject to a publication in the International Journal on Hydropower and Dams.
