description: This work is devoted to combined-cycle thermal power plantâs electrical part design. The research set the following goals: 1. The main scheme of stationâs electrical connections selection. 2. Short-circuit currents calculation for different types of fault. 3. Switching devices, measuring transformers and live parts selection. 4. Measuring transformersâ compliance with relay protection requirements verification. 5. Energy unitâs relay protection basic technical solutionsâ selection. This work covers the development of a thermal power plant project. The main scheme of electrical connections and the scheme of own needs were selected. An economic analysis of the scheme was made. Short-circuit calculation was made for three-phase, two-phase and single-phase fault. Switching devices, live parts, measuring transformers were selected. Relay protectionâs solutions were proposed for a basic energy unit.
