Design of the power supply system for the JSC Perm Plant "Mashinostroitel" enterprise.

As part of this project, a comprehensive power supply solution was developed for JSC Perm Plant Mashinostroitel. The project encompassed a full cycle of design activities, ranging from the analysis of initial conditions and load requirements to the selection of primary and auxiliary equipment.

The following key tasks were successfully completed:

An analysis of the facility was conducted and initial data—including the master site plan and electricity consumption estimates—was systematized.

Production electrical loads were calculated, followed by the creation of a load distribution map.

A reactive power compensation system was designed using synchronous motors and capacitor banks connected to the 10 kV busbars of the main step-down substation.

Specific equipment was selected, including 2KTPN-10/0.4 kV packaged transformer substations and TMG12 and TDN-10000/110 power transformers.

Cable lines were calculated and selected, with verification against current load and voltage drop limits.

Short-circuit currents were calculated to inform the selection of high-voltage equipment for the main step-down substation.

Modern relay protection and automation terminals were selected.

An occupational health and safety section was developed, including calculations for protective grounding systems.

The project resulted in a technically and economically sound design that ensures a reliable and safe power supply for the facility.
