We supplied two “turnkey” generator sets to the biggest combined-cycle power plant in Jamaica

Made to measure energy solution for the Almaraz Nuclear Power Plant

Both the reactors at the Almaraz Nucelar Power Plant in Caceres (the oldest in Spain) supply 7% of the nations energy demands. The plant is located in an area know as Ribera del Rio Tajo, and they have recently placed their trust in GENESAL ENERGY to design an emergency back up generator set capable of dealing with any potential incident.ualidad.

The project consisted in designing, building, installing and commissioning a genset capable of supplying a 110kVA of power to supply energy to the Individual Temporary Storage (ITS), which alongside the fuel pools, allow for temporary storage of used combustibles from the reactors in the event of a power failure.

Genesal has designed a soundproofed genset inside a 20ft container with an interior control room configured for automatic start up. The bench frame incorporates a 700 litre fully bunded fuel tank, providing the genset with up to 25 hours autonomy. The genset has been specially designed to work at 45°C as well as resist seismic movements, in order to comply with security norms.

To meet with the client’s specific needs the genset was designed with an independent control room and power output with various local controls to manage the genset and other parts of the installation.

Load bank

In the switchgear output of the grid/genset, switches are fitted for each area of the ITS in the power plant. Each one can close or open via pushbuttons or using a pre-programmed sequence designed by the client.

For the correct functionality of the genset, a separate room within the container was built to hold a resistive load bank which is connected to the genset output always and when the load is less than 40% of its maximum capacity. This allows for fuel use optimization and prolongs the lifetime of the genset (normally a genset is recommended to work at 70/80% of its maximum).

The load bank can connect to the genset manually via pushbutton for maintenance work. It is also important to highlight the implementation of signals exchange in the Distributed Control System (DCS) of the power plant, for example the state of switchgear, of the genset and a measurement of zero return to detect grounding failure in the installation.

Emergency Power for Phosphates Treatment Plant in El Jadida, Morocco

Situated 80KM south of Casablanca and 17Km from El Jadida is the Jorf Lasar industrial complex, a phosphates treatment plant which Genesal Energy has supplied with 3 specially designed gensets for emergency back-up.

The plant whose installations cover an area of 1,700 hectares began its production in 1986 and its numbers are quite impressive: the recuperation of 2 million tonnes annually of P2Oin the form of phosphorus acid.

Genesal Energy has supplied this elaborate facility in Morocco with a genset island comprising of identical generators for outdoor use (3 units at 400V/50Hz containerised with a control system) designed to work in parallel or if necessary individually. Five circuit breakers make up the switchgear.

Meeting the clients’ specific needs was a key priority, as they wanted to power the facility in two different ways. GENESAL designed the following options:

  1. To power the entire plant using the genset island via an incoming power cabinet situated in the entry area of the plant.
  2. Separate the energy feed between incoming power cabinet in the plant.

This allows for the genset island to feed one incoming power cabinet with all the panels, however if the client prefers to feed both incoming power cabinets, then that is also possible.

IN DETAIL

As with every project undertaken by Genesal, the control system designed for this phosphate treatment plant was managed to the tiniest detail:

  • If the gensets are operational, they can be synchronised, either with the output switch of each genset or with the coupling point, therefore reducing the number of movements required by the switches in case of changes in the operational format.
  • If a generator is stopped, the circuit breaker is disabled to avoid damage from unwanted power inputs from external busbars
  • If the client has not indicated that a connection panel should receive an electrical feed, the incoming power cabinet circuit breaker will not be permitted to close (not even manually), in order to avoid short circuits caused by external voltage not from the actual genset island.

Genesal Energy Electrical Generator, dual voltage and dual frequency

DSC_1299_R

500-550 KVA / 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 OBJECTIVES

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

DSC_1305_R

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
