Hydro Power Station Model

The model of the pumped storage power plant was designed and built as part of absolvent thesis by Jiří Boštička at the Terciary technical school in the school year 2013/2014. The model represents processes commonly found in many industries (chemical industry, petroleum industry, etc.) where a system with transport delays needs to be controlled. The model is connected to a computer using a multi-functional input/output card that allows reading outputs and setting inputs. School resources were used to implement this teaching aid. The cost of the components was 35 493 CZK. The implementation took 885 hours.

Interface inputs and outputs

• Inputs: voltage on the pump motor u_m [V], opening valves v_d, v_p [–]
• Outputs: tank level h [m], voltage at the tachodynamo u_g [V]

Used for teaching

• SS: verification of the laws of fluid flow (continuity equation)
• SS: measurement of the static transfer characteristics of the sensor
• SS: presentation of basic control principles
• TTS: modelling and identification of dynamic systems
• TTS: control of the level in the upper tank with a PID controller
• TTS: tachodynamic voltage control with PID controllers

Design and production of a new nozzle

In 2024, an analysis of the nozzle used was carried out with the aim of maximizing the performance of the Pelton turbine. As part of this project, the nozzle was extended with a cock for better start-up of the power plant. The results of this project are presented in [3].
