Ingeteam Power Technology has been
awarded the supply contract for the world's largest photovoltaic plant, being
built by Sterling and Wilson, one of the leading global solar EPC companies.
The Sweihan PV project, which is to be constructed in Abu Dhabi (United Arab
Emirates), is to have an installed power of 1,177.36 MW. Once inaugurated, this
will be the largest PV project in the world to be constructed in a single
generating power plant.
The energy produced is to be purchased
by ADWEC (Abu Dhabi Water &
Electricity Company), the Emirate's electricity company, a subsidiary of
ADWEA (Abu Dhabi Water & Electricity
Authority), for subsequent transmission, distribution and trading.
The consortium of companies responsible
for the development and operation of the Sweihan PV project, awarded the
engineering and construction work to the Indian company Sterling & Wilson,
which then selected Ingeteam's technology for this project.
Therefore, in early 2018, Ingeteam will
start to supply its new 1,000 Vdc INGECON® SUN PowerMax B series central
inverters, capable of delivering a power output of up to 2,330 kW. These units
are known as dual inverters due to the fact that they combine two power blocks
with a common AC busbar, facilitating the direct connection with the medium
voltage transformer. The solution provided in power station format comprises two dual inverters together with the
other devices required for low to medium voltage conversion. Namely the LV/MV
transformer together with an enclosure housing the medium voltage cells,
auxiliary services transformer, low voltage switchgear, UPS and a cooling
system with air conditioning.
The solution developed by Ingeteam,
known as the Inverter Station,
incorporates two 2.33 MW photovoltaic inverters for the supply of 4.66 MW.
These new dual inverters are suitable for outdoor installation, being specifically
designed to withstand extreme climate conditions, such as those present at
Sweihan in Abu Dhabi.
Moreover, Ingeteam has purchased a
chamber to conduct dust and sand tests in accordance with the IEC 60068-2-68
international standard. This chamber makes it possible to conduct additional
tests, such as the inverter response to sandstorms, which are extremely common at
sites of this type. It has been used to check the correct operation of the
inverter, as well as the efficiency of its "sand trap" system to prevent the
ingress of particles into the inverter, while collecting the grains of sand and
facilitating their subsequent removal. Thanks to this system,
Ingeteam's
PV inverters have been certified by an external body as able to withstand
sandstorms, as described in standard IEC 60068-2-68.
The Management of Ingeteam Power
Technology expressed its satisfaction with the contract award, emphasising the
fact that "the signing of this contract is the fruit of all the hard work put
in right from the outset, marking yet another success in the company's bid to
enter the Middle East market”. Furthermore, the Management highlighted the fact
that "this contract is yet another example of Ingeteam's ability to
develop ambitious large-scale projects".
The commissioning of the plant, for
which Ingeteam is also responsible, is set to take place at the end of 2018.
Once commissioned, the plant will save around 7 million tonnes of carbon
emissions every year.
Scope
of supply
For this project, Ingeteam is to
supply:
- 201 power
stations with a power output of 4,660 kWac. Each fitted with all the
necessary equipment to inject medium voltage power: dual PV inverters, LV/MV
transformer, medium voltage switchgear, auxiliary services transformer, UPS and
low voltage switchgear.
- 402 dual photovoltaic inverters, each
with a rated power output of 2,330 kW, pertaining to the 1,000 Vdc INGECON® SUN
PowerMax B Series family.
- Commissioning of the system.
- Service level agreement, guaranteeing a
99% operational availability of the equipment supplied by Ingeteam during the
first two years of the plant operation.
