Substations

Building substations from Structum

Electrical substations belong to the general energy system. They are responsible for reducing capacity losses, high voltage input into the load concentration centers and maintaining stable voltage on the consumer’s side. Today, it is impossible to imagine our life without electricity. A disruption in power supply even for a short time causes financial losses for businesses and major inconvenience for households.

The electrical energy system of Ukraine was created back in the Soviet era and needs renovation. Many substations now have to exploit worn-out and out-of-date equipment, which raises the issue of substation restoration and maintenance. Besides, it is difficult to guarantee reliable power supply to consumers without building substations and electrical grids of the new generation.

Structum construction company has state-of-the-art technical assets and a professional team allowing it to perform the construction of substations with a voltage up to 750 kV. We are open for cooperation in any format, including the EPC contract framework (engineering, procurement, and construction). It involves the following steps:

  1. Substation design and engineering, i.e. the development and approval of the required specifications.
  2. Site preparation, building temporary facilities and structures for further substation installation.
  3. Installation of the grounding system and laying underground utility lines (plumbing, sewage, oil drainage, etc.)
  4. Building bases for potential transformers, installing a switchyard and busbar systems.
  5. Construction of indoor switchgears, control centers and other auxiliary facilities.
  6. Building an SF6 (sulfur hexafluoride) gas insulated switchgear.
  7. Construction of other required technical facilities and structures (artesian well, fire extinguishing pump station, waste treatment facilities, fire extinguishing water tanks, oil drainage tanks, indoor storages, access checkpoints, etc. depending on the selected design option).
  8. Preparation of cable routes, laying power supply and control cables.
  9. Supply of the necessary equipment.
  10. Substation installation, in particular, power facilities and transformers.
  11. Installation of relay protection systems and controls.
  12. Installation of a distributed control system for technological processes.
  13. Installation of a distributed control system for fiscal electricity metering.
  14. Installation of equipment for the communication systems.
  15. Installation of equipment for the fire alarm, burglar alarm and video surveillance systems.
  16. Startup and adjustment with further commissioning of the facility.

Notably, at the substation engineering and design stage it is important to consider the construction conditions, design the substation layout, and define the type and technical characteristics of the main equipment, the procedure of work setup and connection to the power supply, as well as safety measures.

The experience and professionalism of Structum specialists allows the company to ensure:

  • technical support at all stages of substation construction;
  • selecting an optimal set of equipment;
  • equipment supply at an optimal price and on the best terms;
  • implementing cutting-edge, innovative solutions in substation installation processes;
  • warranty and post-warranty service.

While constructing substations, we use materials from both Ukrainian and global manufacturers to guarantee the reliability and long-term use of the facility. With our expertise and advanced management culture, we minimize the risks and deliver the best results at all stages – from substation design and engineering to commissioning.

Substation restoration from Structum

Structum performs a range of works aimed at restoring substations with the voltage up to 750 kV. The need to restore a substation arises when its equipment is out-of-date, when it becomes necessary to introduce new technologies, comply with the updated regulations, or deal with a change in the system configuration. In this way, you can:

  • increase the reliability of the power transmission system;
  • prevent problems with power supply;
  • reduce technology costs and running expenses;
  • switch your substations to the automatic mode with the possibility of remote management from the main system control center.
