We’ve Reinforced Our Presence in Asia with Gensets in Taiwan, the Ever-Expanding Asian Tiger

/0 Comments/in , /by

At Genesal Energy we’ve opened up a new market in Taiwan through the supply of a 500 kVA generator set designed to supply power in mains failure situations.

Our arrival to the Taiwanese market marks a turning point in Genesal’s internationalization plan in South East Asia. Taiwan is a strategic market, due both to its economic importance as the 28th wealthiest country worldwide and the 6th wealthiest in Asia, and to its potential for companies in the energy industry.

With a GDP that grows at a dizzying rate year by year, the power distribution sector is in constant evolution and with an increasingly strong focus on sustainability. As such, the first project we’ve carried out in the country, a stationary genset of 450-500 kVA, complies with Tier III emission standards. We delivered a genset which was completely adapted to the client’s requirements, providing the adaptability and flexibility needed for a correct integration of all components, with the following features:

  • Stationary, open type genset of 450-500 kVA at 60Hz, 380/220V.
  • DSE 7320 MKII control panel for automatic start at mains failure, with an Ethernet communication module to monitor the genset’s status remotely from a linked-up computer.

Furthermore, our entry into the Taiwanese energy market has been consolidated through the supply of 12 gensets of 200/220 kVA for the Taiwanese Administration. The units, all customised, are designed to enter into operation should a mains failure ever occur. The gensets are stationary and were personalized according to the client’s requirements to be adapted to the modifications that would be carried out at a later date in their facilities. All of them comply with Tier III emission standards.

Main features

  • Open type stationary units of 200/220 kVA at 60Hz, 220/127 V.
  • DSE 7320 MKII control panel for start-up upon mains failure.
  • Engine with EGR valve for exhaust gas recirculation.

We designed an ‘anti-hurricane’ generator set for a great wind farm in the Dominican Republic

/0 Comments/in , , /by

Our engineering team has designed and supplied emergency power to the Agua Clara wind farm in the Dominican Republic, a large power station capable of providing power to 250.000 citizens.

The wind farm, whose first phase has already come to a close, has 25 wind turbines, of two megawatts (MW) each, which represents an estimated annual production of 170.000 MW/hour. 

With an initial investment of 100 million dollars, the project produces 50 MW of renewable power and the objective is to install up to 200 MW once the four phases of the project have concluded. Genesal Energy has designed and supplied a special generator set, adapted to face the complicated climate of the región of Monte Cristi, where the wind farm is located.

Agua Clara is in a hurricane-prone area, which means the wind farm’s infrastructure requires special equipment capable of facing this type of phenomena. In order to reduce the pressure exerted on a wind turbine by a potential hurricane, it must direct its nacelle and blades with the help of electric and hydraulic motors in such a way that the wind exerts the least force possible on the structure, avoiding harm.

One hundred percent personalized

At the windfarm, the client needed that, in the event of a hurricane or a cyclone and in consecuence, a mains failure, the wind turbines could position themselves correctly and avoid serious damage through the use o fan alternative source of energy. To achieve this, we manufactured a generator set capable of powering the auxiliary services which drive the positioning of the windmills.

The generator which we’ve designed is 100% customised and can be completely managed, controlled and monitored from the wind park’s control centre (SCADA). Inside the actual container, the local control system was installed, along with a PLC to manage communication with the farm’s SCADA through fiber optics, and a protection relay.

Genesal Energy ha diseñado y suministrado un equipo especial, adaptado para hacer frente a la complicada climatología de Monte Cristi.

The Genesal Energy unit will receive start-up and shut-down commands from the wind farm’s control centre and will start-up and energize a step-up transformer. From that momento onwards, the genset will power the whole wind farm and, therefore, the auxiliary systems needed to position each one of the wind turbines to avoid damages in the event of a hurricane.

To compensate the capacitance of the medium-voltage cable runs to the turbines, of hundreds of metres of height, an inductor bank was also installed in the wind farm’s substation. The generator set must power the bank during the first seconds after the hurricane, while the wind turbines and the medium-voltage cable runs aren’t being powered. In order for the generator set to be able to support this strong inductive load, its alternator was oversized, through the installation of a top of the range 3.000 kVA alternator.

Features

  • Engine and alternator pre-heaters.
  • ModBus TCP/IP communicaition.
  • Tailor-made control logic carried out through PLC & DEIF AGC4 controller.
  • Dedicated electrical protection relay.
  • Oversized alternator to support high inductive currents.
  • Automatic fuel transfer system.
  • Special application for an anti-hurricane system in a wind farm.

 

Emergency power for the Los Llanos wind farm, a new source of renewable power

/0 Comments/in , , /by

The first wind park to be raised in the province of Malaga was in the Casares municipality and since then the offer for this type of renewable power has not stopped growing.

Genesal Energy’s focus on alternative and sustainable power has also increased considerably in the last decade, with an ever-growing market, and Andalucía is no exception in our line of business.

This way, one of our latest projects has taken us to the Los Llanos wind park, one of the pioneers in this autonomous community, through the manufacturing and supply of a “turnkey” generator set, made-to-measure for the client, which amongst other requirements, asked that the genset be prepared for remote start-up and that it could provide power to the primary loads in the substation facing a possible mains failure.

The generator set, which will operate in Los Llanos, will start-up remotely when the control system of the substation detects a mains failure because precision is vital in this type of installation where wind is the basic power source.

Features

  • Approved double-walled 1.000L fuel tank for outdoors
  • Baseframe fuel tank prepared as leakage tray
  • Electronic engine speed regulation
  • Signal and alarm remote expansion module
  • Remote start-up

Generator load profile and step load explained

/0 Comments/in , /by

Technical article: load profile and consumption of a generator

Knowing the type of loads a generator must power is essential to calculate its required power correctly.

The load profile and the step load —the initial load applied at start-up— are key factors in generator sizing. Power demand is not static; it fluctuates depending on the equipment and conditions, and ignoring these variations can lead to overloads, inefficiencies, or equipment failure.

The power that a generator set manages isn’t an absolute and static value. Its level tends to fluctuate according to certain factors and processes, and it does so differently in each type of unit.

For this reason, calculating the power a generator set needs to function is not a simple operation. Different variables must be taken into account which, if not considered, can cause serious issues in our installation.

For instance, an overload in any of the phases can cause overheating and voltage imbalances. This can cause damage both in the generator set and the equipment connected to it.

Start-up: the first step load

The generator set is going to be limited during its start-up by what is called the first step load, that is: the total transient load that the genset is initially capable of enduring until reaching its stable regime with some transient variations in voltage and frequency.

This is why it’s important to verify the characteristics in the nameplates of the equipment connected to the generator set, and to be aware of the possible transient effects which they may suffer during its start-up processes. 

Certain equipment such as pumps or motors with variable drives, for instance, may increase their current temporarily during commissioning. 

Likewise, elements such as UPS’s (uninterruptable power supplies) can cause harmonic distortions which must be contemplated in our calculations.

Which parameters affect the dimensioning of loads? 

  1. The first parameter to contemplate is the type of load. As we’ve pointed out, some units experience transient increases in current during start-up. With this in mind, we’ll pay special attention to the following loads:
  • Uninterruptable power supplies (UPS). The alternator’s rated power is oversized depending on the installation.  
  • Big motor loads. They can increase starting power to up to 6 times the power, depending on the type of start-up.  
  • Lighting loads (with special attention to sodium vapour lighting and metal halides). 
  • Systems with Variable Frequency Drives (VFD). These can cause an oversizing from 40 to 100%. 
  • Other loads which are especially sensitive to transients and voltage and frequency variations. 
  1. Another factor we must keep in mind is the type of start-up of the motor in question. This is due to the fact that each type of starter requires a specific starting current, which must be higher than the unit’s rated current. Thus, we find that:
  • Electric motors with star-delta starting: its “starting current” will be equal to three times the rated or operating current. 
  • Direct starting motors: demand 6 times nominal current. 
  • Starter motors with variable frequency drives: special attention must be payed to its technical sheet as normally the ramp and increase in speed is configurable. 

Other important aspects to consider for genset load calculation

To finish carrying out this entire calculation of power with maximum precision, other variables must be kept in mind such as: 

  • Power factor during start-up.
  • Starter power.
  • Rated power factor.
  • Rated power
  • Efficiency
  • Number of start-ups

Ultimately, we must be extremely rigorous in this calculation. To avoid any surprises, it’s vital to know the type of load we’re dealing with as well as its behaviour. All, with the objective of the generator set always powering a balanced load, without generating unexpected peaks.

10 Benefits of having a power generator set

/0 Comments/in , /by

Technical article. 10 benefits and advantages of electric generators

In a world increasingly dependent upon energy, technology and data, it is a priority to have a reliable and sustainable supply of electricity. This is precisely what generator sets offer us.

The importance of electric generators

The importance of generators lies in their ability to provide continuous power during outages and support critical infrastructure. In times of natural disasters or unexpected power failures, generators ensure that hospitals, data centers, and emergency services remain operational, safeguarding lives and essential data. Moreover, they enable businesses to maintain productivity and prevent financial losses, highlighting their crucial role in modern society.

However, the virtues of these devices go beyond what meets the eye and it is worth knowing them. We compiled a list of 10 fundamental benefits so that none of them is left out:

What are the main advantatges of having a generator set?

1. Uninterrupted Power: The Importance of Ensuring Continuity

Electricity supply no matter what. Generator sets are meant for you to always have electricity whatever happens. This means that problems with the electrical network will no longer be critical for you, given that you will be constantly backed up by an autonomous generation solution which is 100% effective.

2. Say Goodbye to Downtime: Boosting Productivity

Farewell to losses: relying on the backup of a generator set in your business allows you to forget about time and productivity losses supposed by power blackouts.

3. Empowering Autonomy: Expanding Possibilities

More autonomy, more possibilities: when using an energy distribution solution such as a genset you are no longer dependent on the limitations imposed by the infrastructure of the electrical network. This means more peace of mind and, most of all, more freedom when it comes to conceiving your business projects and letting them fly.

4. Mobile Power Solutions: Enhancing Flexibility

It allows you more mobility: generator sets allow you to have a power supply in areas lacking an electrical network. Therefore, they eliminate obstacles when it comes to carrying out projects and they contribute to the development of remote or disadvantaged areas.

5. Tailored to Your Needs: Customized Designs

Your project is in charge: at present, the design of gensets is tailored to the clients’ needs and the features of their projects. According to your requirements, you will be able to choose: between engines using different fuels, between stationary or mobile generators, between hybrid and marine generators, as well as between different profiles of power delivery and of use.

6. Adding an Extra Layer of Protection: Ensuring Security

An additional security layer: the consequences of a power outage go beyond the mere issue of productivity. A sudden “blackout” can cause severe damage to our devices and machinery and this is something that can be avoided if we have the backup provided by an emergency genset.

7. Sustainable Energy: Reducing Environmental Impact

It contributes to sustainability: as opposed to the great impact left by the emissions produced by thermal power stations, generator sets offer a model of energy production which increasingly allows one to leave the least possible environmental footprint. The present-day trend is represented by generators using fuels with low CO2 emissions, like natural gas or liquefied petroleum gas (LPG). Moreover, these are low noise devices, producing no sound pollution.

8. Long-Term Value: Making a Sound Investment

It is an investment which pays off: A generator set will give you an extremely valuable service and will continue to do so for a long time. Most certainly, with appropriate use and maintenance, you will have a safe, long-term investment.

9. Streamlined Energy Production: Enhancing Efficiency

More efficient energy production: statistics show that electricity losses in the Spanish network of transport and distribution amount to 8% of all available production. Using distribution solutions such as gensets, one manages to reduce such losses. Moreover, we contribute to avoiding overloads in the network during the peak hours.

10. Cutting Costs: Maximizing Savings

You save in consumption: gensets allow you to reduce costs, by helping you manage the electricity demand in a more economical way. For example, you can use them as a backup during peak hours, in order to avoid excessive consumption. According to calculations, you can save up to 40% in this time slot.

 

In short, a generator set brings you peace of mind, opens up a large spectrum of business opportunities and all this in an effective and sustainable way.

Do you think it could be an interesting solution for you as well?
