Dual frequency and dual voltage gensets for an international construction company

/in , /by

Design process thought out and revised to the very last detail.

Gensets that operate at different frequencies as well as different voltages are special units whose design process has been thought out and revised all the way down to the very last detail. One of our latest orders comes from an international building company who needed gensets capable of being moved from one place to another and of operating at different frequencies and voltages, as the client has construction projects in different countries around the world.

Features

  • 730-800 kVA units prepared to operate by manual and automatic start in the event of a mains failure, at 480/277 Vaz 60 Hz and 400/230 Vac 50 Hz.
  • The change of voltage and frequency is carried out from the control panel with a switch for the adjustment of frequency and a potentiometer for the adjustment of voltage.
  • At the same time as the frequency is selected, the control panel is reprogrammed with the values corresponding to the selected voltage and frequency.

7 units of soundproof generator sets

Genesal Energy designed, manufactured and delivered seven 15/16 kVA soundproof gensets mounted on trailers to the client’s installations in Northern Europe.

The project consisted in the supply of seven mobile soundproof gensets. These units were designed to operate at both of the country of destination’s voltages (400/230 V & 230 V 3 phase without neutral). Each unit possesses the adequate power sockets to operate at both voltages.

Remote communication system

The seven units include a remote communication system through a GPRS module that allows the operation of the unit through SMS or through an app available for both iOS and Android. In addition, these gensets incorporate a GPS system that allows the client to trace the units, that is, to know exactly where they are at any given moment.

Genesal Energy Electrical Generator, dual voltage and dual frequency

500-550 KVA genset designed for industry leader in cold storage installations for the South American market.

The client, an industry leading company in cold-storage facilities, had a special request: On the one hand, they needed and emergency backup power option for their manufacturing plant at 50Hz. However, they also need an alternative energy source to carry out testing on machinery (freezers, water recovery systems etc) at 60Hz for products which would be sold to Latin American markets. Because of the different voltage and frequency used in Central & South American countries the power grid in the client’s European base prevents them from testing products in authentic conditions. Hence the reason for an alternative power source to allow testing in the conditions found in Latin American markets. It was for these reasons that GENESAL ENERGY designed a “dual frequency” solution to meet all their needs.

GENESAL ENERGY developed a specific project to ensure a power supply with two power supply functions:

  • Emergency back up to provide electricity to the clients European manufacturing plant in case of a power grid failure.
  • Provide an electricity source for testing machinery built with different voltage and frequency.

Project summary

Design and manufacture of a 500-550 KVA genset to operate in emergencies, giving an independent power supply in case of a power grid failure to two workshops at 400/230 V 50Hz. At the same time, it will also give a power supply to a testing bench at 400/230V 50Hz or 460/266V 60Hz in manual mode.

Project goals

Was to design a genset with three operational modes:

  • Emergency power for workshop 1 at 400/230V 50Hz
  • Emergency power for workshop 2 at 400/230V 50Hz
  • Power supply for a testing bench at 400/230V 50Hz or 460/266V 60Hz

Solution

We opted for a newly designed 4500mm long canopy, with a view to easy access for maintenance and mechanical operations, along with an 800l fuel tank integrated in the base frame, to ensure a constant power supply for extended periods before having to refuel.

Only one control panel was installed for the entire control of all operations required from the genset, and at twice the size of a standard genset control panel This was integrated in to the interior of the genset with a front access window panel for visual access, although for safety and security, access is only gained by the authorised key holder to the control panel

Features

  • Dual voltage and dual frequency
  • Modbus TCP-IP (IB-LITE) communication device
  • Oil extraction pump
  • Automatic start up in case of grid failure
  • 800L internal base frame integrated fuel tank with
  • connections for future link to external fuel tank
  • Up to 11 hours of autonomy at 80% load, or 18
  • hours at 50%.
  • Battery disconnector
