We designed a generator set for one of multinational company DSV Sweden, prepared to operate in the extreme cold

/in , , /by

We designed a soundproof 450-500 kVA unit prepared to withstand the cold temperatures.

Low temperatures are a critical factor for many companies that manufacture gensets due to the difficulty of designing competitive products that are prepared to operate in the extreme cold in an optimal manner.

This is not the case for Genesal Energy, which has a specific range of gensets that are capable of starting-up and operating intemperatures of up to -30ºC, which has made our brand a reference brand in Scandinavia, as well as other countries in Northern Europe.

One of our latest projects in this “low temperature” range has been for DSV, the Danish logistics and transport company, the fifth in its sector at a worldwide scale. The multinational company needed emergency power for one of its logistics centres in Sweden, and for this it reached out to Genesal.

To meet with DSV’s needs, we designed a soundproof 450-500 kVA unit (GEN500SI) prepared to withstand the cold temperatures.

The unit was installed in DSV’s logistics centre in Jönköping, a municipality located 350 km to the south-east of Stockholm with icy autumns and winters, where the thermometres show temperatures that easily dip below zero degrees.

The genset includes oversized batteries and has heaters integrated in the canopy, in order to maintain the unit at the correct temperature so that it is in perfect conditions to start-up in the cold in the case of a mains failure and guarantee the electricity supply to the centre.

Ecuador’s Government installs Genesal Energy generator sets in the Quito Sur Hospital, the largest and most modern hospital in the country.

Covering almost 90,000 sq./m, costing 226 Million US dollars, and fully operational since December 2017, Ecuador’s largest and most up to date hospital has been built in South Quito, the capital.

Covering almost 90,000 sq./m, costing 226 Million US dollars, and fully operational since December 2017, Ecuador’s largest and most up to date hospital has been built in South Quito, the capital.

The project commissioned by the Ecuadorian national health service (IESS), is today a reality, and benefitting the residents of south Quito, in the El Recreo district. This publicly owned hospital with over 400 beds and 50 consultation areas, employs 1,800 people. Each one of the 5 buildings within the complex contains a Genesal Energy emergency power genset.

Power cuts in hospitals can lead to critical situations for patients and the doctors and nurses that care for them. It is obviously vital that these types of buildings can continue to function and must not be brought to a standstill.

The high consequences of a power cut mean it is essential to install back up systems that will continue to supply electricity to all the systems, ensuring the medical teams and doctors can continue their work ensuring that patients continue to receive healthcare.

Project aims: Emergency Power at Quito Sur Hospital in Ecuador

Due to the risks presented by a power cut the client required a solution that would incorporate gensets with automatic start-up (AMF). GENESAL ENERGY designed six generator sets with different voltages and power ratings, to meet the clients needs in relation to the different load requirements for each building. The objective; a guaranteed power supply in the event of a mains failure permitting the hospital to carry on as normal.

Designed for high altitude

The gensets supplied can give the necessary power at an altitude of 2,800M above sea level, bearing in mind that at this altitude there is less oxygen in the air, meaning the gensets mist work harder.

Additionally the solution had to account for the need to install gensets that would not cause noise contamination, and for this reason soundproofed gensets were supplied with the exhaust system at the top of the canopy.

Characteristics

  • Top canopy exhaust system.
  • Automatic fuel transfer from external fuel tanks.
  • Pre-heating resistance included.
  • Automatic start-up due to mains failure.
  • Ethernet connection.
  • PMG excitation system.

Supply of seven mobile soundproof gensets with a remote communication system

/0 Comments/in , , /by

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 has supplied an emergency genset for the combined cycle power plant (CCPP) known as Empalme II, a huge engineering project in the Sonora State of Mexico

/in , /by

Back start 2,000 kVA genset

Empalme II is a thermal energy combined cycle power plant with 2 gas turbines and output peak level of 791 MW, an initiative led by the Federal Electricity Commission (CFE in Spanish) of Mexico. Empalme II is a fantastic example of a large-scale engineering project in Sonora State, of which Genesal Energy has had the privilege of participating in. Our role has been to install a black start 2,000 kVA genset, whose purpose is to restore full functionality and start up of the power plant in the event of a mains power cut. The genset has been developed uniquely for this customer and as part of the overall project.

Back start 2,000 kVA genset

Alongside Chihuahuha and Baja California, Sonora is a reference in Latin America as a whole for the commissioning of projects which promote the use of renewable energies. In installations such as Empalme II, whose investment borders on $400 million, the inclusion of gensets is fundamental. This is for a variety of reasons, for example in CCPPs there are essential loads which must be permanently supplied with power for the correct functioning of the installation.

At Emplame II one of the most important loads is for the turning gears or barring gears, consisting of an electric motor which turns the turbine shaft at low speed to ensure balanced cool down and avoid rotor bending or “hog”. In terms of automation, the client asked for System Control And Data Acquisition (SCADA) to be available in the main control panel.

How does it work

In these cases, the emergency genset is connected to the main electrical power cabinet, which at the same time is connected to three different busbars, feeding the panel for general essential services and the essential services for the 2 gas turbines. In an emergency, the genset will feed the essential loads in the power plant and will even be capable of identifying each busbar individually, permitting it supply energy either individually or together.

To correctly install this system, Genesal Energy proposed a redundant PLC using 2 computers, so if one should breakdown, the other will immediately and automatically take full control of the genset, without any noticeable change in the rest of the power plant. Additionally, protection relay was installed and a synchroniser allowing parallel operation with the mains grid. The genset also includes an electrical control room with air conditioning, fire detection and suppression system that can differentiate where it will operate in the genset using FM200 gas agent.

Emergency Power for the Saudi Arabian embassies in Ghana, Cameroon, Niger and Zambia

/0 Comments/in , , , , /by

Design and manufacture of emergency back-up gensets for the Saudi Arabian embassies situated in Ghana, Cameroon, Niger and Zambia, ensuring they will continue to have electricity in the event of a power cut in the mains grid supply.

The first stage in partnership with the construction firm responsible for building the embassies was a rethink to ensure that the gensets were adequately installed according to their characteristics.

The final design was completed, followed by the acquisition of the required materials to ensure the production deadline was met. Finally, the gensets (both mechanical and electrical parts) were built, culminating in testing for approved standards certificates in conjunction with the consultant responsible for design approval and signing off on the delivery.

Energía de emergencia para las embajadas de Arabia Saudí

A total of 20 gensets have successfully been installed: four in Ghana, five each in Niger and Cameroon, and a total of six gensets in Zambia. Although the gensets appear to be very similar, they were configured differently in each room where they have been installed, depending on the position of the fuel tank as well as the accompanying cables.

This also included the need for adequate busbars for the fitting of the power cables to the gensets. Each embassy now has a set of gensets giving back up support to the main on-site buildings. Regarding the genset operational setting, depending on the embassy, this could entail running in parallel between the gensets. It also permits added power output or redundancy, useful where if one genset fails, the others or another will take up the load demand. The project was completed with individual gensets installed in to the underground bunker found in each compound.

Gensets for a solar power plant in South Africa that will supply electricity to 150,000 homes

/0 Comments/in , /by

Genesal Energy contributed with the project design and supply of two emergency gensets.

Kathu Solar Park in South Africa is a concentrated solar power system(CSP) up to 100MW. Building commenced in May 2016, and it is destined to be in service by the end of 2018.

The thermoelectric plant itselfwill be able to supply 4.5 hours of thermal energy thanks to cutting edge technology which allows supply to continue well after the sun has gone down. When fully operational Kathu Solar Park will supply power to 150,000 households. Also, according to the construction management team, the installation will contribute to sustainable development in the province of North Cape where the plant is situated. This will result in a C02 emissions saving of 6,000,000 tonnesover the next 20 years.

Genesal designed the emergency gensets in compliance with a series of requirements. The gensets had to be soundproofedand the control room needed to be maintained at an optimal working temperature. This was achieved by installing a split air conditioning system and a heat exchanger.

    

Remote Control

Rock wool acoustic panels inside a metallic mesh cover were used for soundproofing, guaranteeing an excellent attenuation result, functionally, but also aesthetically. The interior of the generator set was split in to two clearly defined compartments: the engine room and the control room. The emergency gensets can be controlled either directly via the in-built control panels using buttons, switches and touch screen technology or it can be controlled remotely through a DCS (distributed control system) which is a method to centralize and controlthe entire power station.

Alongside the gensets two double walled certified fuel tanks were supplied for external installation, one at 7,500 litres full load, and the other at 10,000 litres, guaranteeing over 24 hours of autonomy if necessary.

 

Made to measure energy solution for the Almaraz Nuclear Power Plant

/0 Comments/in , /by

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.


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

/in , /by

The project has been designed for one of the most important companies in the engineering and constructin sector, with headquarters in Marseille (France).

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 P2O5 in 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.

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.

We are involved in the extension of the Los Azufres plant in Mexico, which obtains renewable energy from the centre of the earth.

/in , /by

The genset supplied by Genesal Energy is ready to power the critical loads at2,856 M above sea level, where the plant is situated.

Geotherm is a renewable energy source which is generated by the heat expanding from the core of the earth. Currently, Mexico is one of the most advanced countries in this field, and in Los Azufres the country’s second largest reserve also one of the biggest in the world is found (the largest in Mexico being in the state of Baja California).

The Los Azufres power plant is located in the state of Michoacan, 250 KM from the capital Mexico City. Due to the potential of this energy source, the Federal Commission for Electricity has driven the construction of Los Azufres III-Phase 2 expansion, with a net capacity guarantee of 25MW. This will be focused on supplying power to the Michoacan cities of Hidalgo and Zinapecauro. The objective is to ensure a stable and renewable supply for the ever-increasing energy demands in the region.

Genesal Energy has supplied emergency back up power for the plant, a made to measure generator set, very different to standard gensets, in that it can operate at almost 3000M above sea level.

The generator set, was the result of an exhaustive study detailing all the technical requirements of the project. Various aspects were analysed such as the conditions the genset would be working in, as well as calculating the loads it would support and the load steps in order to determine the most adequate engine and alternator.

The role of the new generator set in the Los Azufres Geothermal Plant is to supply power to the critical (essential) loads in the case of a mains grid power failure, with the objective of bringing the power plant to a safe shutdown and not a sudden stop. This is achieved using an Automatic Transfer System (ATS) to switch the power from the mains to the genset.

Some other interesting facts about this Project

  • The control panel was designed to a very specific specification, which was supplied by the client’s engineers – requiring a control cabinet with a PLC (Programmable Logic Controller) and a Siemens Siplus touchscreen.
  • The control panel and the entire genset installation has been prepared to work in an environment with a high concentration of H2S (sulphuric acid – a gas which is heavier than air, inflammable and colourless). To protect against H2S and for easy maintenance all the PLC cards are covered with an acrylic based plastic. Additionally, the connectors on the cards and where they connect are gold plated to withstand a permanent concentration of 3mmm of H2S gas.
  • It comes with a Modbus tcp/ip card and a fibre optic converter via a manageable switch with two fibre optic ports to create a fibre optic ring and guarantee continued communications.
  • As well as communication, the most important signals are sent wired. This ensures all the genset information is stored in the Scada system in the DCS of the geothermal plant, and total control via SCADA.

Genesal Energy continues to consolidate its standing in central America with a specially designed genset for Panamanian television

/in , /by

Panama National Television (TVN), one of central Americas most important, has put their trust in to GENESAL ENERGY by asking us to design a super-compact electrical generator, adapted to their energy demands.

Having the ability to transmit their signal problem free from anywhere within the country of Panama, led TVN to realise and understand the importance of a genset that can supply energy to all of their field equipment. Whether it is to ensure an interview goes off without interruption, or a live connection remains live, TVN have chosen Genesal Energy to help them reach their large central American audience.

A fundamental part of the project was the ability to attach and suspend the genset to their mobile transmission trailer. For this reason alone, it was clear that a highly robust, super compact genset was required to be able to resist various situations, such as poor roads, inclement weather, stone or mud spatter when travelling etc. This was a clear case of designing a personalised genset, a speciality of Genesal Energy.

Small size, big power

A key part of the GENESAL ENERGY solution was to design a genset which was very compact (2286x758x752mm) to fit correctly to the chassis of the TV truck. A 50-litre fuel tank was integrated in to the solution, and removable panels have been added for ease of access for maintenance and servicing.

Additionally, inlet pipes and outlet pipes were designed to be compatible with the movement of the trailer, taking in to account the direction it is travelling, and ensuring the genset is not at risk of damage.

The genset control unit is remote, and has also been designed by Genesal Energy. It contains all the functions required, alarms and the necessary protections as requested by the client, for safe supply of electricity to their connected apparatus (cameras, microphones, lighting etc).

Another key area requiring a prioritised solution was related to the noise emitted by a genset in operation, which can cause interference when the TV crew are recording material. The solution; we designed a soundproofed canopy using noise absorbing material, capable of reducing noise emission from the genset to levels sufficiently within those that are required for TVN to produce their audio-visual requirements.

The project has been successfully completed and most importantly delivered. Installation and commissioning was also supervised by our on-site team, and TVN now has a TV truck with the freedom to operate where the news is happening.
