team: Djordje Dobrijevic - Project Manager; B. Sijakovic, Nebojsa Jovic - Consultant
The main goal of this study is to provide to TSO all necessary information for study on connection of the revitalized unit of TPP, installed power of 367MVA, after first phase of revitalization in which only turbine should be replaced. The unit is connected to 220kV voltage level of the electric transmission grid of Serbia. Following design studies have been provided: checking of voltage-reactive capability and selection of proper step-up transformer ratio; load flow studies including contingency analysis; fault calculations; static stability studies and transient stability studies including CCT calculation; mid-term stability analysis; checking of requirements defined in national grid code.
