An electrical power supply system for industrial enterprises consists of power supply, distributing, transformer, and conversion substations and of the cable grids and high- and low-tension power lines connecting them.
An electrical power supply system is constructed in such a way that it is reliable, convenient, and safe to service and assures the necessary quality of power and uninterruptibility of the electrical power supply during both normal and emergency modes of operation.
At the same time, an electrical power supply system must be economical in costs, annual expenditures, energy losses, and expenditure of materials and components. Economy and reliability of an electrical power supply system are achieved through interlinked backup of an enterprise's diverse electrical power systems.
