description: The given work is devoted to designing electric circuit, based on South Coge-neration Plant (SPb) and transformer protection. The research set the following goals: - Choice of the electric circuit and the main equipment (genetators, transformers, breakers); - Calculation of three-phase short circuits; - Choice of auxiliary equipment (switching devices, live parts, current and voltage transformers); - Calculation of unbalanced short circuits; - Block protection. As a result of the work, the main circuit diagram for the electrical connections of the TPP was developed and the models of the main equipment were selected based on the technical and economic analysis. Further equipment selection depended on the specific short-circuit currents that can pass through the devices. Therefore, the calculation of three-phase short circuit currents was performed for all possible points of the circuit. A selection was made of devices that meet the requirements of the nominal parameters of voltage and current, as well as the conditions of electrodynamic and thermal resistance. Single-ended short-circuit currents were calculated for two points on the high and low side of the power transformer. Based on the rules, recommendations are given on how to protect the block.
