САЖЕТАК / ABSTRACT:
In accordance with the requirements for the connection of new users of DS in the consumption area of substation TS 110 / 20 / 10 kV „Jagodina 3” and the fact that in TS 110 / 20 / 10 kV „Jagodina 3” on page 20 kV are already connected KDS in the industrial zone at the power level of 20 kV and that TS 35 / 10 kV “Jagodina I” is powered. Due to its limitations in power and radial power over DV 110 kV No. 1227 „Jagodina 4 – Jagodina 3″, it is not possible to provide the necessary security and reliability in the power supply of new industrial plants. Two options are considered: The first solution, which would provide the safety criterion “n-1”, increase reliability in the power supply and expand the existing capacities of this TS is to build a new DV of 110 kV based on the “input-output method” of DV 110 kV No. 105 / 2 “TE Morava Jagodina 4”, as well as to install another power transformers. The second solution (temporary until the completion of the implementation after the first solution) is the purchase of a 35 / 20 kV energy transformer installed with a power of 8 MVA which would be installed in TS 35 / 10 kV “Jagodina I ” at the place of transformer No.2. This transformer would be connected by a 20 kV cable and would allow recharging of the 20 kV panes at the TS 110 / 20 / 10 kV substation „Jagodina 3“ in case of power transformer failure at the TS 110 / 20 / 10 kV substation „Jagodina 3“ or power line failure. Due to the fact that the implementation of the contract for the connection of TS „Jagodina 3“ with TL 110 kV number 105 / 2 was planned for the end of 2026, and after the completion of the electricity analysis and the need to ensure safety and reliability, a second solution was also launched which will be temporary until the completion of the work after the first solution.
