[ Year: 2025 ]

[ Country: Ukraine ]

[ Industry: Energy industry ]

Key Features:

implementation of a full cycle of electrotechnical solutions for cogeneration units;
work with medium and low voltage networks (10, 6, 0.4 kV) within a single facility;
integration of generating equipment into the enterprise's existing electrical grid;
ensuring stable distribution of electricity between external consumers and internal needs;
execution of works taking into account the requirements of reliability, redundancy, and power supply safety.

Implementation:

Main electrical solutions:

The CHP unit generates electricity at a voltage of 10 kV;
power transmission via power cables to generator switchgear units;
transmission via a bus bridge to the incoming switchgear units;
integration into existing distribution points.

Distribution and transformation:

power distribution at 10 kV and 6 kV levels;
transmission to a block-complete transformer substation;
stepping down the voltage to 0.4 kV to meet the facility's own needs.

Installation and connection:

installation of electrical switchgear units and execution of commissioning works;
laying of power cables and performance of tests;
installation of step-down transformers;
installation and connection of equipment power supply systems.

Support systems:

arrangement of primary and emergency lighting systems;
redundant power supply based on battery systems.

Result:

Stable and safe operation of the facility's power supply system has been ensured, with the capability to transmit electricity to both external consumers and for internal needs.
The implemented system allows for effective integration of the cogeneration unit into the existing energy infrastructure, complying with the requirements for reliability and continuity of power supply.
