TKC Computer Controlled Kaplan Turbine

COMPUTER CONTROLLED KAPLAN TURBINE - TKC

INNOVATIVE SYSTEMS

The Computer Controlled Kaplan Turbine, "TKC", is a small scale Kaplan turbine (reaction turbine). Kaplan turbines are used in many parts of the world for electricity production, as they cover the lowest water sites and are especially suitable for high flow conditions.

General Description

The Computer Controlled Kaplan Turbine, "TKC", consists of a small-scale Kaplan turbine that has a ring with adjustable guide vanes, which allow the control of water flow in the turbine.

In order to raise the fluid, it has a computer controlled pump that enables the impelled flow to pass through the turbine, in which part of its energy is left, causing the turbine to turn, overcoming the external resistance caused by an electromagnetic brake. This computer controlled brake makes it possible to vary the braking load on the turbine.

In addition, the unit is equipped with a pressure sensor placed at the turbine water inlet which measures the inlet pressure, a flow sensor to measure the turbine water inlet flow, an optical sensor which determines the speed of the turbine shaft, and has two pressure sensors at the pump inlet and outlet, in order to obtain its characteristic curve.

The pump-turbine group has a tank and a pipes system which allow to work constantly with recirculated fluid to avoid the indiscriminate water consumption.

This Computer Controlled Unit is supplied with the EDIBON Computer Control System (SCADA), and includes: The unit itself + a Control Interface Box + a Data Acquisition Board + Computer Control, Data Acquisition and Data Management Software Packages, for controlling the process and all parameters involved in the process.
