Planning, design and construction management of hydro-electric power plants

Equipment

Slovenian producer of water turbines

PV6 - 2600kW (2)

P = -μ ((ρV)g ∆h)

A simple formula for approximating electric power production at a hydroelectric station where:

  • P – is power (in watts)
  • μ – is the coefficient of efficiency (a unitless, scalar coefficient, ranging from 0 for completely inefficient to 1 for completely efficient)
  • ρ – is the density of water (~1000 kg/m3)
  • V – is the volumetric flow rate (in m3/s)
  • ∆h – is the change in height (in meters)
  • g – is acceleration due to gravity (9.8 m/s2)

BOKAhydro runners are based on proven designs and CFD calculations:

Our Pelton runners can achieve efficiency up to 92%
Our Francis runners can achieve efficiency up to 94.5%
Our Kaplan runners can achieve efficiency up to 94%

We transform your vision into concepts and solutions

We give our customers comprehensive support during complete hydro-electric project

Development process

BOKAhydro offers its knowledge in terms of study in order to maximize the return on investment of its customers and partners giving the possibility to realize partially or completely the preliminary studies taking in account not only the equipment design but also the civil engineering from the water intake to the restitution..

Turn-key solution

The high complexity of hydro power projects requires the cooperation of large number of experts form various fields. Our company combines knowledge as geology, sismology, hydrology, civil engineering, mechanical engineering and electronics, energetis, telecommunications, sensor technology and much more.

After-sale service

Uninterruptible electricity generation and optimization of the power plant as a relatively complex issue.

  • On site services
  • Scheduled maintenance; Consumables & Spare Parts
  • Remote control support, daily
  • Plants performance optimization
  • Damage analysis

Francis runner implementation

Given the Economic viability of the project and the Characteristics of the hydro-electric power plant, we advise different designs of Francis runners; milled from monoblock, welding solution (in the middle of the runner blades and between runner hub, blades and rim) and casting.
