Good morning good afternoon and good evening

welcome to this

industry best practice session on wind turbine

In this presentation we will share an

overview of the

key benefits of simulation and the capability

required to realize

this benefit during the development and the

operation of wind

turbines and wind farms through multiple example I

will try to

showcase to you how Ansys portfolio

solution are helping

our customer to design transformational

products we will finally

close the session with a summary of important

information on

how to learn more about this topic and also

about

some additional material available for you at

the booth

So

to start with I would like to

share with you a short reflection on the

engineering challenge

that wind turbine manufacturer and operator

are facing during the

design of the wind turbine but also during

the entire

life of these machines so to start with during

the

last decade we have seen that the diameter of

the

wind turbine rotors were getting bigger and

bigger both for

onshore

and offshore application so this huge rotor

dimension comes with

many engineering challenge mostly related to

structural reliability of the

of the blades but also related to some

logistics and

transportation challenges The second point

here in order

to capture

each time a larger amount of energy with

highest wind

speed for which the wind turbine is operated

this has

come with this has increased a lot during the

past years

and this is also associated not only with the

management

of very large aero loads due to this very high

speed but also this adds a lot of complexity

in

the design of the safety control loads of the

wind turbine

itself

As we are looking for increasing higher power

output I'm

stating here up to 12

million

watts per turbine sorry 12

megawatts per turbine I believe that this

come also with

a lot of challenge related to thermal

reliabilities as an

example all the electrical components such as

generators transformers converter

inside the nacelle or inside the tower

depending on

the design of the wind turbine so all these

components

are submitted to very high load which are

associated with

a lot of heat loss and this heat starts

becoming

very critical for the reliable operation of

such electrical components

so

we might might even to also add that in since

the

example of offshore application this

challenge is even bigger as

a wind turbine operates under severe

condition severe environment with a lot of

humidity and salt

all these had a lot of constraint to the

design

of the nacelle and the tower under ambient

conditioning

Now moving on outside somehow the wind

turbine in the

past 20-25 years many of the good location

where to

install wind farm have been already

used and filled

with a lot of wind turbines and right now the

challenge is to design a proper layout for

wind farm in

remote location we can think about mountain

range or perhaps

designing proper windturbine sorry wind farm

layout closer and closer

to the city closer to urban areas this

comes

with a couple of challenge that both

manufacturer of wind

turbine and operator need to solve first the

noise footprint

related to the wind farm and secondly

the optimization of the position of the wind

turbine inside

the wind farm for example making sure that

the wake

of one row of wind turbine is not impacting

that

much the performance of the second row

Good well up to now I I just pointed out

some challenge that were related to the

design and

the installation of the wind turbine but there

is also

a whole additional set of challenges that

come with the

operation of the wind farm

I mean the wind turbine is this

machine they are

here to stay very long more than 30 years and

the maintenance operations

are predominant in the total cost of the

machine itself

during its entire life so if I here also try

to just take an example

If a failure occurs somewhere on an offshore

wind turbine

in addition to the loss of energy

during

a certain amount of time

there is a huge cost associated

to the

fact that an operator needs to go on site and

to repair a very costly part so the question

then

is that what the industry the wind turbine industry

would like

to solve is can we anticipate such

failure

Is there a way to predict when I need to

replace specific components on wind turbine

Well all this challenge I would

like to

spend some minutes now trying to show to you

in

our Ansys this is helping to solve all these

engineering

challenge But I would like you

not to

take my word for granted and I would like to

give you some proof points

and I will try to refer to what Ansys

customer

are achieving by using our solution

Here are three examples the first one is

really related

to the capacity of one of our customers to

double

double the power output of a generator by

using our

multiphysics solution design the second one

is this time related

to 80%

saving in cost of the material for the design

of

a very innovative

blade for a small wind turbine urban

wind turbine in

that case and finally this one is not about

design

it's about 5%

increase in energy production

which is a huge revenue

uplift

which is associated to the usage

of our digital

twin solution for an entire park for an

entire farm

of wind turbine

So these are the types of quantified

outcomes that

you can expect when you are working with

Ansys solution

Now more specifically I would like to

provide you

an overview

of the key benefits that Ansys is bringing

to achieve such outcome OK along the

following capabilities that

we identified for you 6 capabilities

engineering capabilities that we

would like to go a bit deeper right now

first rotor aerodynamics and acoustics we'll go

then towards

some specific application related to

structural design

n nacelle in tower also for the rotor and

all manufacturing application related to this

technologies then we'll go

through power generation and transformation

and then moving outside of the wind turbine

itself going

into the design of the wind farm

plus finally on two specific topics related

to the

development of control system and safe

operation of the

wind turbine and finally going into the

condition based maintenance

capabilities and utilization of digital twin

to monitor the activities

of an entire set of wind farms

So let me now go for you through this six

different topics

and I would like to start with the rotor

aerodynamics

and acoustics the engineering challenge that

wind turbine manufacturers are

trying to solve here are the following

The first one is related to being able to

have

a good design that is able to capture as much

as possible of wind energy

problems challenge they are trying to solve

together with this

design is operating in harsh condition

There is a degradation that is related to the

accretion

of ice on the blade I also mentioned earlier

that

the noise footprint is something that is

critical when we

are looking for Installation of the wind

turbine and there

is also submitted to certification somehow

and finally these big

blades big rotors are submitted to a lot

of

deformation due to the aerodynamic loads and

this needs to

be taken into account also in the design

process how

Ansys is helping well we're providing

capability to simulate

the entire 3 dimensional field for aero

acoustics aerodynamics

we have vertical solution dedicated to the

calculation of ice

accretion on the blade and an open platform

on which

we can do coupling we can calculate coupling

effect

between the deformation of the blade and the

aerodynamic load

some example of output you can get from this

Ansys

capabilities while you will manage to get an

accurate power

curve estimation early in the design phase of

the rotor

and for sure for different type of wind

regime

so really along all the power curve of your

wind turbine

Specifically calculating some force and moment

acting on the wind turbine that

will be useful to then calculate

deformation of

the blade

ice accretion could be calculated as I

mentioned and this

will help you to design possible system to

clean their

eyes or even to even imagine some anti-ice

design

system with some heating pad Finally we will

be able

to you will be able really to to in the

context of certification to anticipate the

noise level the DB

level around the wind turbine and so pass

the

qualification criteria also early in the

design stage

Moving to the second part which is related to

more

the structural design of blade nacelle

and towers here engineering challenge

are related

first and foremost to the cost reduction and

the mass

reduction of this component material is a key

topic when

we're talking here about mass and cost

reduction and finding

the right material for the right wind turbine

application is

a challenge of all structural engineers or

structural department within

the wind turbine manufacturing community this

is also tightly related

to technology related to composite when we're

talking about blade

composite is something an advanced composite

characteristic is something that

could be a challenge

for blade designer and finally it's not only

about design

for performance it's also design for

logistics it is designed for

transportation and all these components all

this

business critical application needs to be

taken into account at

design level

How Ansys is helping to solve this

challenge

We are providing a unified material

management system which can

handle very complex loads analysis and even

including some characteristics

about logistics

In terms of efficiency of the of the

different structural

component we have associated multiphysics

workflow

dedicated vertical solution for composite

material

that are spanning from the design of the

blades themself

up to the manufacturing process of the blade

so you

can take into account all these process

within one single

solution and this is embedded into a

framework which is

enabling to do some optimization of all this

parameter altogether

some output you will get

The aerodynamic load scenario that you will

be able

to simulate is huge you will also be able

to take into account some wave load for offshore

characteristic

in the foundation of the wind turbine or the

jackets

that you are using and you will be able to

be able to anticipate that very early in the

design

stage First time right composite molding

manufacturing no mistake you

will save a lot of prototype in the in the

manufacturing stage and massive weight and

material cost reduction can

be expected and we have some proof points for

that

with some relevant examples

Moving now to let's say the more electrical

component related

topic everything related to power generation

and transformation typical engineering

challenge we want to highlight here how about

the increasing

power density to meet the growing demand from

the market

improving the grid stability and interconnect

control

and what about the extra energy that the grid

cannot

get how about the storage the batteries

perhaps of the

unused power these are all relevant

challenge that wind turbine manufacturer

and operator operator system are facing

days and night

Ansys capability addressing the challenge of

the following we have

a comprehensive electro-mechanical meaning

multi physics capability to design

generators

At the grid level a system circuit design

is

able to be done within Ansys to predict

system performance

and varying electrical loads

what you will get out of this Ansys soluti

systeon

you will be able to verify

the generator efficiency and its

performance

taking into account system components such as

gears blade and

also electrical cabling so not only focusing

on the generator

itself but everything all around it

You will be able to anticipate what will be

the

generator temperature and also acoustic

capabilities that will help you

design a proper cooling system for the

generators

Finally power conversion circuitry at the

component level but also

at the system level will allow you to

do the sizing and also the design of the

control

software for this application

we are now moving to the fourth topic which

is related to wind farm so we are moving we

are zooming out of the turbine and now

looking at

the wind farm itself and typically the

engineering departments that

we are looking and the companies that we are

looking at wind

farm might be very different compared to the

engineers that

look at the different component we just

analyzed in the

three previous slide typically these are

people that are looking

for energy prediction on large scales typical

challenge here is

to anticipate the loss due to the wake

inside the farm meaning the weight of

different turbine

within the farm and also all the challenge

related to

where to locate this farm can we locate this

close

to a city can we locate a wind farm around

a forest for example these are the type of

problem that

wind sitting engineers are facing

What are we bringing what Ansys is bring

well

knowing that these engineers are not expert in

fluid dynamics

we developed an automated workflow a specific

application which allows them

with very low amount of experience in

computational fluid dynamics

to be able with our best practice

to derive full simulation for a wind farm

including weight

loss including overall assessment of the

energy that is coming

yearly from this wind farm this is a kind of

output they will get so I just mentioned this

so the detail assessment of the farm behavior

with under

specific wind condition speed direction

and even to do some cost prediction with

existing

data that you might have gathered on specific

mast

sorry on location

Overall the expectation and what you will get

the outcome

you will get will have to have the best wind

turbine layout for the selected location you

are working on

and at the same time maximize the energy

output

OK moving now on control system and software

engineering challenge

that wind mine manufacturers are expected to

face here are

the following this is our control software

I mean is

our control with a lot of

standards

and there is a lot of standards rated to safety

safe operation of the control itself

so controlling in general typically

we spend a lot of effort to integrate the

different

best practice they have internally about

control software and the

integration of this effort should be

compatible with the existing

safety standards Plus complex wind turbine

control and system monitoring

are more and more the case compared to 10

years

ago because the operation of the wind turbine

are also expected

to I mean the wind turbines are expected to

work in more severe conditions

Ansys is bringing an integrated functional

safety analysis platform

that will allow control engineer to work not

only and

to make sure that not only their control

system is

safe but also are corresponding to the

software design and

requirements that has been defined upfront

Theywill be also able to do some model

level

testing at early in the design stage

of

the controller and not only wait to have

their model

to be compiled and are coded into the final

controller

Example of output the first and

foremost one

is at our solution

Is bug free so the output you can expect and

you can expect on your team it's a huge

reduction of effort rated to the verification

of the code

itself and your code will be by default

compliant with IEC 61508 certification which

is applicable for wind turbine

so we made sure from the very beginning

that

code generator that we are providing to you

is certified

automatically for your specific application

Finally last but not least this one is

related to

predictive maintenance of the wind farm and

the application of

digital Twins engineerings' challenge could

be the following fatigue and

the cost associated to fatigue

is some things that need to be anticipated

during the

whole life of the wind turbine

Others unplanned down time sorry and

the maintenance

costs are something also introduced at the

very beginning of

this presentation and really are

driving the total

cost of the wind turbine itself it's not only

about

design it's much more about the operation of

the wind

turbine

Also being able to anticipate nonoptimal

operation of the wind

turbine if there is something occurring at

component level here

the example of yaw misalignment these are

the typical

challenge that a wind turbine operator would

like to anticipate

Ansys is bringing capabilities modeling

capabilities simulation capabilities including

3D

so 3 dimensional reduced order modeling

that will allow fast and I insist and

accurate calculation

of

fatigue stress point and also you will be

able to

define virtual sensor within your digital

twin you won't need

to equip your wind turbine with a huge

amount of

physical sensor but you can accurately rely

on this virtual

sensor

Example for outputs of our solution you will

be able

to continuously monitor the structural

response of your wind turbine

and have all this information almost

instantaneously you won't

have to wait for a couple of weeks to have

any report on that it will be live

information

real time prediction that's what I

mean of

the actual

behavior of the wind turbine but also about the

remaining life

of each individual wind turbine this will allow

you to

better schedule maintenance operation and

even to generate performance index

for the entire wind farm

And I was telling you that you should not

take

my word for granted Here are some more proof

points

I will invite you in the next few minutes

after you finish listening to this

recording to go

to the material of the booth where you can

download

the PDF of this presentation and you can also

find

some nice collateral you will find some

customer stories

here are three of them for leaders both in

the

wind turbine manufacturing field but also in

the operator and

you will see how we are quantifying the

output and

the outcome that our customers are getting by

using our

simulation solution

that

could be of interest for you both going a bit

deeper into the technical topic with some

tips and tricks

webinars even some training sessions and also

some application brief
