We designed the gensets for two biomass power plants: the Viseu and Fundão power plants, in Portugal

Genesal Energy has designed and supplied two special gensets for two biomass power plants in Portugal

The Viseu and Fundão power plants, two twin installations which, according to experts, will prevent the emission of 88.400 Tn of CO2 to the atmosphere. Both are a prime example of clean, renewable energy production.

Biomass power plants are thermoelectric power plants that use organic matter as fuel, whether it be of plant or animal origin, susceptible to being used for power purposes. These installations generate electricity through the combustion of the biomass to heat the steam in boilers. The steam, in turn, moves a turbine which spins a generator, which transforms the electric power into mechanical power.

As this process relies on combustion systems, great quantities of power are needed to cool the power plant’s systems to guarantee its operation.

Slow combustion

In the event of a mains failure, the biomass power plants must be brought to a safe shut-down. To achieve this, it’s neccesary to maintain and power different cooling systems in order to avoid material or personal damages due to the overheating of the systems as, by its own nature, biomass combustion is a slow process.

In the event of a mains failure, this type of installation must be brought to a safe shut-down

If an electrical failure arises in this kind of power plant, the biomass inside its boilers will continue to burn, generating thermal power which won’t dissipate if the cooling systems aren’t operational. At Genesal Energy, we designed two units for these plants capable of starting up when a failure to power the essential services’ busbar is detected.

If the genset in question starts up and starts powering loads, the power plant will be in the process of shutting down and during this time it’s fundamental the cooling systems be active.

This way, when the genset is powering loads, even if mains returns, the power plant operator is the only one who can stop its operation and bring back mains power, guaranteeing that the shut-down process is always carried out in safe conditions.

Maximum security

On the other hand, each of these units has different security systems which prevent the control over the breakers that power the essential systems’ busbar by other systems which aren’t the actual genset, in order to avoid short circuits due to errors in the operators’ handling.

The manifactured units are capable of starting up as soon as a failure to power the essential services

The only moment in which a system other than the genset can control the busbar’s mains breaker is during the power plant’s start-up, as in that moment the genset won’t be active.

Technical Features

  • Remote control panel in the installation’s electrical room
  • 1000 L base frame fuel tank
  • Fuel filler neck on the outside of the container
  • Installation in a 20” soundproof container with an air outlet silencer to achieve a sound level of 85dB at 1 metre
  • Communication via MODBUS TCP/IP with power plant control system
  • Integrated web server with access from the power plant’s control system
  • Genset load system in a sequence of up to 14 steps.

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.

We supply a 900 kVA genset.

Another accomplishment by our distributors has allowed us to supply a 900 kVA genset prepared to run parallel to mains in one of the most luxurious areas of the UK, guaranteeing continuous electric power supply in the residential area in which it was installed.

Features

  • 1,500 L baseframe fuel tank featuring a leakage tray with a capacity of 110% the capacity of the actual fuel tank.
  • Parallel to mains with double automatic magnetothermic breakers, one of them motorised for parallel to mains operation and the other a manual breaker for connection with the load bank to carry out load tests with the already installed genset.
