Wind farm backup generators

Efficient energy
with wind power

It does not pollute, is inexhaustible, and is available almost everywhere in the world. Wind power is the most efficient of all renewable energies.

Energy that is inexhaustible, just like our generators

In 1994 the first wind farm was launched in Spain, making it one of the pioneering countries in harnessing wind power to produce electricity. This was a type of energy that did not generate waste, did not pollute, and generated wealth thanks to the creation of numerous local jobs. Today, almost 30 years after that “boom”, the wind power sector is still experiencing a buoyant period.

Generators for wind farms Genesal Energy

The construction of wind farms equipped with wind turbines is a solid and expanding market where we have a strong international presence, due both to our initial commitment to renewable energy, and the use of R&D+i in the design and manufacture of generator sets designed for this type of installation.

The consumption of clean and sustainable energy seems unstoppable, so meeting the demand of this sector with the best emergency equipment is a priority for us, which is why our engineers have a thorough knowledge of this constantly evolving market.
Wind farms have a large number of wind turbines that generate clean energy from wind power. These wind farms are usually located in very windy areas in order to maximise their operation.

When wind turbines have no power, or are unable to generate power, they must be able to continue to face the direction of the wind. This is especially true in the case of strong winds such as those caused by hurricanes, with speeds greater than 100 km/h. To orientate towards the wind, the generators require auxiliary power. If there is no electrical network available, the generator sets must take over the auxiliary power supply to these installations to prevent strong winds from breaking the blades of the turbines.

Customised efficient energy

Generator sets in wind farms are essential. They must be a part of the project from the beginning as they are vital both in the event of contingencies in the electrical system and during the first stages of commissioning of the power plants.

At Genesal Energy, we are perfect connoisseurs of the renewable energy sector and specialists in reinforcing the efficiency of this type of wind farm, based on innovation and large doses of cutting-edge technology. For these installations we have a wide range of possibilities that we manufacture according to the client’s requirements, and the characteristics of each generator set are the result of an exhaustive analysis of all the factors that contribute to shaping the wind farm, including the location infrastructure.

How we size generator sets in wind farms

We can categorise the generator sets for anti-hurricane systems into two types:

Individual generator sets for a wind turbine, or, for a group of nearby wind turbines.
Generator sets to supply energy to all the wind turbines in the wind farm.

In either case, the generator set must be custom designed to:

Guarantee correct integration with the anti-hurricane control systems and SCADA systems of the wind farm.
Guarantee reliable and safe communication between the wind farm control systems and the generator set. These sets integrate the most advanced communication technology using fibre optics.
Facilitate the detection of breakdowns and maintenance of the generator set to maximise its availability.

Pros and cons

	Generator sets per wind turbine	Generator sets per wind farm
Voltage drop in power cables	The distance between the generator set and the wind turbine is small, so the voltage drops in the cables will be negligible.	The distance between the generator set and the wind turbines is very large (several kilometres) so it is necessary to adequately size the wiring between the generator set and the turbines.
Number of generator sets	The generator set only powers a maximum of 3 wind turbines that are close to each other, so multiple generator sets are required on the wind farm.	Several generator sets are installed in parallel to supply the power demanded by the wind farm.
Size of generator set	Small generator sets.	Large generator sets in parallel.
Control of the generator set	The starting and stopping is done at the request of the anti-hurricane system of the wind turbine itself. Integrations can be made with different communication protocols.	Generator sets start due to grid failure, and depending on the power demanded by the wind farm.
Reliability	By feeding fewer wind turbines, in the event of a failure of one of the generator sets, only the wind turbines connected to it would be affected. The rest of the wind turbines would continue to be supported.	If the generator sets fail, the available power may be less than required and the entire wind farm may be left without power during the hurricane.
Maintenance	Increased requirement for labour for the maintenance task by having several generator sets distributed throughout the wind farm.	The generator sets are centralised in a single area, so all the equipment can be maintained without having to travel.
Reserve equipment	In the case of a failure of one of the generator sets, it is possible to have a reserve generator set available, given their low cost.	The cost of having reserve equipment is very high due to the size of the equipment.
Size of the alternator	The loads are, to a greater extent, engines driven by variators. The alternator is usually not very oversized. The cost is insignificant.	Apart from the loads, the inductance and capacitance of the cables must also be taken into account as they may be laid for distances of tens of kilometres. The alternator is greatly oversized to be able to power the loads with the losses caused by the wiring. The cost is quite significant.
