"Aston Hall", Frantsuzky Bulvar 60/1, Odesa. Complex implementation of main and backup power supply systems

“Aston Hall” is the first clubhouse in Ukraine with the infrastructure of a five-star hotel.

 

Our goal in this project was to develop and implement optimal engineering solutions for:

  • ensuring the reliability of the complex’s power supply for critical engineering systems with backup from independent autonomous sources;
  • Provide centralized intelligent data collection and processing on the state of the main components of the power supply system;
  • improving the fire safety of the complex.

The scope of work included:

  • development of concepts and technical specifications;
  • development of design solutions and engineering documentation;
  • electrical installation works;
  • production, supply, and installation of equipment;
  • commissioning works;
  • preparation of as-built documentation.

During the construction of this complex, engineering and installation works were carried out in the "Power Supply" direction, specifically:

  • electrical solutions (power electrical equipment and lighting);
  • building facade lighting;
  • external lighting of the complex territory.

Scope description of the main proposed and implemented engineering solutions in the "Power Supply" direction:

The main power supply of the facility is based on an integrated substation 10/0.4 kV with two dry power transformers rated at 2500 kVA. 

Schneider Electric equipment is used in the substation: 

  • 10 kV cells based on gas-insulated RM6 monoblocks,
  • dry transformers 10/0.4 kV Trihal, 
  • 0.4 kV busways (3200 A) based on the Canalis KTA complete solution, 
  • main distribution board (MDB), and automatic reserve input panel (ARIP) for 0.4 kV based on the Prisma P design.
 

The main distribution board of the 0.4 kV substation is equipped with reactive power compensation installations based on the comprehensive solution by Schneider Electric.

 

The main distribution board of 0.4 kV, guaranteed power supply panel, and automatic reserve input cabinet are equipped with automation devices based on programmable relays with Modbus/TCP interface, which are integrated into the overall power supply monitoring system of the facility.

Backup power supply

The backup power source for critical engineering systems of the complex is a diesel power station P1100E1 with a capacity of 1100 kVA, manufactured by Wilson. 

 

All commercial premises and each apartment are provided with a backup power supply.

 

To ensure guaranteed power supply, an uninterruptible power supply (UPS) – APC Galaxy VS 20 kW was used.

 

Backup and guaranteed power supply for equipment are provided from dedicated panels manufactured from protective and switching equipment by Schneider Electric using separate cable lines.

Power distribution across the floors

is ensured through vertical busbar trunking Canalis KTA and Canalis KSA, which enhance reliability and fire safety of the complex.

 

For electricity distribution to consumers, separate floor distribution boards based on Prisma G, Pragma, and Spacial SF designs are installed, equipped with protection devices from Schneider Electric’s Compact NSX and Acti9 series.

 

The selection of all automatic circuit breakers in the distribution boards at all levels is based on calculations of short-circuit currents at each individual connection point, using the advantages of cascading for automatic circuit breakers from Schneider Electric.

Power distribution across the floors

All important switching and protective equipment is equipped with additional contacts, and all power grid monitoring devices are equipped with Modbus/TCP interface.

 

The power supply network incorporates a surge protection system by Schneider Electric to protect against voltage surges.

 

The completed power supply system has undergone comprehensive testing by the electrical laboratory of “Concern “Ksimex” LLC in strict compliance with current standards and regulations, and it has been handed over to the Client for commissioning.
