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.
