The RTL PLCs of the “Mihailo Pupin” Institute, developed and produced by our company Automatika, now manage the reversible hydroelectric power plant “Bajina Bašta.”
The replacement of the old relay logic was carried out as part of the revitalization project of the control system of the aforementioned reversible power plant. Under the new business conditions, reversible power plants are very important for the operation of the power system, especially regarding renewable energy sources. The only reversible hydroelectric power plant within EPS Bajina Bašta is an important reserve in Serbia’s power system during periods of increased consumption or dry spells.
Within our Institute, the hydrotechnical department handles the SCADA system, i.e., complete power plant management algorithms, as well as all HMI displays.
“We are responsible for the complete power plant management system, control panel cabinets (KTA), protection cabinets, as well as auxiliary system cabinets of the power plant. In addition to this part, for which we are highly specialized, we also work on the energy-related part, i.e., we deliver and install disconnectors for electrical braking of aggregates, current and voltage measuring transformers, and surge arresters. Our SCADA system is already in place at the power plant, which we need to adapt and integrate with new modules and subsystems,” says Milan Bjedov, Head of the Department for Control Systems in Hydroelectric Power Plants.
From the “Mihailo Pupin” Institute, our chief management designer is Ivana Bačvanski Janjatović, who works alongside young engineer Tanja Duvnjak as she gains knowledge.
As in the period from 1976-1982, when the power plant was built, the main contractor now is the Japanese company Toshiba, which is set to deliver the new turbine. In addition to the “Mihailo Pupin” Institute, Goša montaža, Jadran, and the “Nikola Tesla” Institute, responsible for the excitation system, were engaged as subcontractors on this project.
