This article presents a method for measuring the geometry of crane rails with terrestrial laser scanning (TLS). Two sets of crane rails were divided into segments, their planes were adjusted, and the characteristic rail lines were defined. We used their profiles to define the positional and altitude deviations of the rails, the span and height difference between the two rails, and we also verif...

1. Introduction The Acoustic Scintillation Flow Meter (ASFM) measures flow velocity in directions perpendicular to pairs of parallel acoustic beams. In its simplest hydroelectric power plant applications, the ASFM's acoustic beams originate from horizontally-aligned pairs of adjacent transducers mounted on intake walls or on the vertical members of frames designed to fit into intake gate slots....

Supervisory control and data acquisition (SCADA) systems are increasingly used to operate critical infrastructure assets. However, the inclusion of advanced information technology and communications components and elaborate control strategies in SCADA systems increase the threat surface for external and subversion-type attacks. The problems are exacerbated by site-specific properties of SCADA e...

Slapy hydroelectric plant (HPP) is a typical mid-head HPP hosting three 50 MW Kaplan turbines on the Vltava river, 50 km south of Prague, Czech Republic. The gross head is 47 ÷ 53 m in normal operation regime. Pressure-time (PT) flow measurement method was specified for the acceptance tests of the upgraded Unit #3 in autumn 2011 and OSC had the contract for those tests. ASL AQFlow proposed to b...

For enhancing the regulation performance and efficient operation of pumped storage power plant, this paper proposed to combine a hydro-generator set with full-size converter achieve decoupling control machine grid. On basis model test, characteristics certain pump-turbine had been discussed implication for was highlighted. At same time, modeling side were presented, simulation results showed th...

The present work is in the framework of water resource control and optimization. Specifically, an advanced process system was designed implemented a hydroelectric power plant for management. Two reservoirs (connected through regulation gate) set turbines energy production constitute main elements process. In-depth data analysis carried out to determine variables major issues related previous co...
