description: Subject of the final qualification work: Design of the power supply system of a residential complex in the Resort district of Saint Petersburg.
The volume of the work is 73 pages of text, 11 figures, 18 tables, 13 sources of literature.
Keywords: transformer, short circuit, power supply, cable line, switchgear, grounding.
The objective of this work is the design of power supply of residential complex, residential complex will be the construction of three apartment buildings of different heights, kindergarten, food shop, cafe and furniture store.
The final qualifying work consists of an introduction, the main part consisting of eight chapters divided into paragraphs, conclusions and a list of references.
In the introduction, the relevance of this final work is presented, the goals and tasks that need to be solved are defined.
The first Chapter describes a summary of the residential complex.
In the second Chapter, the calculation of the loads of the residential complex was made, the calculation was made using SP 31-110-2003 Design and installation of electrical installations of residential and public buildings, the calculated data are summarized in tables.
In the third Chapter, the type of transformer substation was determined and the power transformer capacity was selected, taking into account normal and post-accident loading, and the location of the 10/0.4 kV TP was also selected.
In the fourth Chapter, the selection of cross-sections of cable lines, 10 kV supply cable and 0.4 kV outgoing cable lines from the transformer substation to the load was made, as well as checking for long-term permissible current and checking it for voltage losses.
In the fifth Chapter, the short-circuit currents of 10 kV and 0.4 kV are calculated, 
the short-circuit points were determined and the replacement circuit was drawn up according to the design scheme, the calculated data are summarized in tables.
In the sixth Chapter, the choice of switching devices 10 and 0.4 kV is made. The RM6 type CRU was adopted as the 10 kV CRU of the designed TP, and the SRC Assembly was adopted in the RUNN, in which the selection of switching devices for the input, sectional and outgoing load lines was made.
In the seventh Chapter, the cable lines are checked for thermal stability in the event of a short circuit.
In the eighth Chapter, the calculation of the grounding device of a transformer substation is made according to the conditions of the rule for the device of electrical installations.
In conclusion, the results and main conclusions of the final qualification work obtained as a result of the work carried out are summarized. Calculations and selection of electrical equipment were carried out according to the normative and technical literature.
