description: Theme of final qualification work: Â«Design of 110 kV substation and 20 / 0.4 kV network for power supply to the cultural and historical center in St.PetersburgÂ». This work is devoted to the development of electrical parts of substations 110/20 kV and BKTP 20 / 0.4 kV, taking into account modern and reliable electrical equipment, as well as taking into account the parameters of the spectral loads of KIC when substantiating the choice of power transformers in BKTP taking into account their throughput. Tasks that were solved during the research: 1. The definition of the source data for the design of the substation 110/20 kV. 2. Load analysis, calculation of short circuit currents, selection of switching devices and live parts, taking into account the requirements of regulatory documentation. The choice of cable lines between 110/20 substation and BÐ¡TS 20 / 0.4 kV. 3. The choice of the power supply scheme of the CHC Â«PoltavaÂ» taking into account the requirements of state standards. 4. The choice of power transformer in BÐ¡TS 20 / 0.4 kV taking into account the reduction in throughput due to the presence of non-linear load. The electrical part is connected to a 110 kV switchgear of the ELK-04 type, 20 kV switchgear cells of the Volga type with VD4 vacuum circuit breakers, and molded current conductors of the TKLS type. BCTS is made on the basis of dry transformers with cast isolation of Trihal type and gas-insulated cells RM6. For communication between PS and BCTS, a cable with XLPE insulation is used. Given the composition and category of reliability of power supply, the load of the CHC Sailing ship Â«PoltavaÂ» is a circuit diagram of the main switchboard. Current values of energy losses in transformers and the influence of higher harmonics of current on their value. Taking into account the adopted characteristic spectral composition, the load is calculated taking into account the correction for the coefficient of the rated current of the transformer 20 / 0.4 kV and its capacity is checked.
