Description
COMPLETE SPECIFICATION
METHOD FOR THERMAL MANAGEMENT OF AN ELECTRIC POWER
CONVERSION INSTALLATION AND INSTALLATION FOR IMPLEMENTING
THE METHOD.
BACKGROUND OF THE INVENTION
The present invention relates to an operating method or a method for thermal
management of an electric power conversion installation. It also relates to an
electric power conversion installation implementing such a method. It lastly
relates to a computer program comprising computer code means suitable for
execution of steps of the method.
STATE OF THE ART
The invention applies in particular to electric power supply sub-stations for
high-power industrial applications integrating power electronics devices.
In most electric power distribution rooms equipped with transformers and
medium-voltage and/or low-voltage panels, forced ventilation is used to
remove the heat dissipated by the equipment. This ventilation is controlled
according to the temperature inside the room. Heating resistances are also
provided to keep an acceptable temperature level for the equipment and
condensation problems in case the outside temperature is very low and/or the
power dissipated by the equipment is not sufficient to keep the temperature in
the room at a sufficient level. If forced ventilation becomes insufficient (very hot
climatic conditions, very great dissipated power), an air-conditioning unit is
used to maintain an acceptable temperature in the room. Generally speaking,
in applications where power electronics devices are used, such as data
storage centres for example, it is usual to air-condition the premises to
dissipate losses.
In the case of certain power electronics devices, use is made of a heat transfer
fluid to collect the heat in the vicinity of the static switches and to remove it
either directly with an air exchanger or with an iced water production unit.
These different solutions present certain drawbacks:
- heating resistances, like air-conditioning, are large electric power
consumers and no longer correspond to the energy efficiency criteria
demanded today;
- the use of air-conditioning is not very dependable and gives rise to
maintenance problems in addition to high investment costs,
- the use of a heat transfer fluid requires the use of a fluid network that is
hardly compatible with the proximity of electric equipment.
SUMMARY OF THE INVENTION
A first object of the invention is to provide an electric power conversion
installation enabling the problems brought up in the foregoing to be remedied
and improving known installations of the state of the art. In particular the
invention proposes an installation that is simple, economic and efficient.
A second object of the invention is to provide an operating method of a
conversion installation enabling the energy efficiency to be optimized while at
the same time minimizing energy losses at the level of the installation.
The invention relates to an operating method of an electric power conversion
installation, the installation comprising an enclosure in which a voltage
converter and a power electronics device are arranged, said operating method
comprising implementation of different routings of a heat transfer fluid
according to the operating state of the power electronics device and/or
according to the thermal environment in which the installation is located.
In a particular embodiment of the operating method, an on state and a standby
state can be distinguished in the operating state of the power electronics
device, and a high thermal state, in particular when the temperature of the
environment is higher than a first threshold, and a low thermal state, in
particular when the temperature of the environment is lower than the first
threshold, can be distinguished in the thermal environment.
A first routing of the heat transfer fluid enabling the thermal energy of the
voltage converter to be dissipated to the outside of the enclosure when the
power electronics device is on and/or when the thermal state of the
environment is high is preferably implemented in the operating method.

voltage converter to be dissipated in the power electronics device when the
power electronics device is on standby and when the thermal state of the
environment is low is preferably implemented in the operating method.
A third routing of the heat transfer fluid enabling the thermal energy of the
power electronics device to be dissipated to the outside of the enclosure when
the power electronics device is in operation is preferably implemented in the
operating method.
Recirculation of a fraction of the heat transfer fluid, at the level of the power
electronics device, in the third routing is advantageously implemented in the
operating method when the thermal state of the environment is low.
In an electric power conversion installation according to the invention
comprising an enclosure provided with a first compartment in which a voltage
converter is arranged and provided with a second compartment in which a
power electronics device is arranged, the installation comprises hardware
and/or software means for implementing the operating method as defined

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
An embodiment of an installation according to the invention is described in the
following with reference to figures 1 to 5.
The installation is designed to be located outdoors. It comprises an enclosure,
which is for example prefabricated and may be movable, in which the electric
components of the installation are placed. For this installation to be able to be
placed in the majority of geographic areas, the installation therefore has to be
able to operate over a wide range of ambient temperatures (for example
comprised between -30° and + 40°C). Outside this range, it is possible to use
an installation having particular features.
The installation has to present a high index of protection IP to be insensitive to
rain and not to stir particles able to be detrimental to the electric components.
The installation can be placed close to the sea. In this case, salt filters also
have to be provided to protect the electric components.
In this type of installation, the most sensitive components are the power
electronics devices. In general, this type of component is dimensioned to
operate at temperatures comprised between 0 and +40°C. The upper limit is
imposed by the maximum thermal resistance of static switches. The lower limit
is imposed by two different phenomena:
- the behaviour of static switches: at low temperature, static switches switch
faster and generate voltage surges which may be destructive;
- the performances of the heat transfer fluid internal to the components are
impaired at low temperature.
These phenomena occur during the rest phase of power electronics devices
just before they are switched on. Self-heating of static switches then suffices to
prevent these phenomena.
It can therefore be clearly seen that, taking account of the operating conditions
sought for, four operating modes are necessary giving rise to contrary
problematic situations:
- in hot periods and in operation (for example +40°C ambient), the air flowing
at the level of the installation has to remain below 40°C;
- in hot periods and in shutdown phase (for example +40°C ambient), the air
contained in the enclosure has to remain at an acceptable temperature for
the installation (for example less than 45°C);
- in cold periods (for example -30°C) during shutdown phases, the
temperature in the enclosure has to be able to be maintained or increased
for correct operation on restart;
- in cold periods (for example -30°C) and in operation, the air flowing at the
level of the installation has to remain at an acceptable temperature (for
example 0°C).
To enable management of the thermal energy in the installation, the installation
1 comprises an enclosure 30 or a room. This room comprises a top wall 21, a
bottom wall 20 and side walls 22 and 23. The room comprises a first
compartment 6 and a second compartment 3. The first compartment is
designed to accommodate a voltage converter 7. The second compartment is
designed to accommodate the power electronics device 2. The first
compartment 6 is separated from the second compartment 3 so that the heat
generated by the voltage converter 7 does not disturb cooling of the power
electronics device. The second compartment further preferably comprises a
raised floor 5 and/or a hood 51 above the power electronics device.
It should also be noted that the first compartment comprises a fan or an
assembly of several fans 11 to make a heat transfer fluid external to the room,
such as air, circulate according to a first routing inside the first compartment. In
this way, thermal energy can be exchanged between the inside of the first
compartment, in particular between the voltage converter 7 and the outside of
the room. This heat transfer fluid circulation takes place via a first opening 12,
provided with a flap, in the side wall 22, and via a second opening at the level
of the fan 11. For example, if the heat transfer fluid enters the first
compartment at the level of the opening 12, this first opening is equipped with
a filter 9. Thus, when the flap of the opening 12 is opened and the fan 11 is
started up, the heat transfer fluid enters the first compartment at the level of
the opening 12, flows in the first compartment around the voltage converter,
and then exits from the first compartment at the level of the second opening
associated with the fan 11.
In symmetric manner, the second compartment comprises a fan 16 to make a
heat transfer fluid external to the room, such as air, circulate according to a
routing inside the second compartment. In this way, thermal energy can be
exchanged between the inside of the second compartment, in particular
between the power electronics device 2 and the outside of the room. This heat
transfer fluid circulation takes place via a third opening 15, in the side wall 23,
and via a fourth opening 18 in the side wall 23. For example, if the heat
transfer fluid enters the second compartment at the level of the opening 15,
this opening is equipped with a filter 9. Thus, when the opening 18 is opened
and the fan 16 is started up, the heat transfer fluid enters the second
compartment at the level of the opening 15, flows in the second compartment,
around and in the power electronics device, and then in the hood 51, then exits
from the second compartment at the level of the opening 18.
The opening 15 is advantageously located underneath the raised floor 5 and
openings are provided, in particular underneath the power electronics device,
to enable the heat transfer fluid to pass from the volume under the raised floor
to the frequency converters and to the rest of the second compartment. For
example, the fan 16 is fitted just above the power electronics device. The heat
transfer fluid can preferably flow in the rest of the second compartment after
flowing in the volume under the raised floor and before flowing around and in
the power electronics device.
As a variant, the opening 15 is not directly at the level of the raised floor but is
located on one or more external surfaces of the second compartment 3 and
thus enables a direct air flow between the outside and the inside of the second
compartment 3, particularly in the case where the raised floor does not exist.
As another variant, the opening 15 is split into several openings - at the level of
the raised floor and on one or more external surfaces of the second
compartment 3.
At the level of the hood, a flap 17 is advantageously provided to enable
communication between the hood and the rest of the second compartment.
A partition 8 further separates the first and second compartments. This
partition comprises a fifth opening provided with a flap 13 and a sixth opening
associated with a fan 14. One of the fifth and sixth openings is preferably made
between the first compartment and the volume of the second compartment
located underneath the raised floor.
In this way, when the flap 13 is opened and the fan 14 is started up, the heat
transfer fluid coming from the second compartment enters the first
compartment at the level of the opening 13, flows around the voltage converter
in the first compartment, and then exits the first compartment at the level of the
opening associated with the fan 14 to return to the second compartment. A
heat exchange between the voltage converter 7 and the power electronics
device 2 can thus be achieved by a heat transfer fluid routing.
In the figures, the elements referenced 9 are filters, in particular filters
presenting a high index of protection IP and/or comprising a salt filter. The
elements referenced 10 are grates presenting a lower index of protection IP.
The flaps 12, 13 and 17 are preferably of motor-powered type.
The main thermal constraint is imposed by the power electronics device which
has to be permanently ventilated with a heat transfer fluid the temperature of
which does not exceed 40°C. It is moreover the power electronics device that
generates the most thermal losses for an installation as described in the
foregoing.
The installation comprises all the hardware and/or software means for
implementing the operating method or the thermal management method that is
the object of the invention. In particular, the installation comprises hardware
and/or software means for implementing each of the steps of the method that
is the object of the invention and enabling each of these steps to be articulated
logically and/or temporally. Although it is not represented, the installation
comprises a logic processing unit enabling the different items of equipment to
be controlled, in particular the motor-powered flaps 12, 13 and 17 and fans 11,
16 and 14. The installation advantageously further comprises sensors enabling
the state of operation of the installation, in particular the state of operation of
the power electronics device, to be determined, and sensors enabling the
thermal state of the environment in which the installation is located to be
determined.
A mode of execution of the operating method of the installation according to
the invention is described in the following with reference to figure 5.
In a first step 100, the thermal state of the environment in which the installation
is located is tested. If the thermal state of the environment is high, we go on to
step 110. If the thermal state of the environment is low, we go on to step 120.
For example, the thermal state of the environment is considered to be high if
the temperature outside the enclosure 30 is higher than a first threshold, for
example 0°C, and the thermal state of the environment is considered to be low
if the temperature outside the enclosure is lower than this first threshold.
In step 110, it is tested whether the power electronics device is on standby or
in operation. If the power electronics device is in operation, the installation is
configured as described in the following with reference to figure 1.
In this configuration, the flap 12 is open, the flap 13 is closed, the fan 14 is off,
the fan 16 is on and the flap 17 is closed. Moreover, the fan 11 can be
activated with different levels. So long as the temperature inside the first
compartment is not too high, the fan 11 can be off. It is switched on to prevent
the temperature of the first compartment from exceeding a threshold, for
example 40°C. For this purpose, it can be put into operation at different
speeds.
Thus, in the first compartment, air external to the enclosure is inlet via the flap
12, flows around the voltage converter, and is then discharged to the outside
by the fan 11. This enables the voltage converter to be cooled. In the second
compartment, air external to the enclosure is inlet via the opening 15, flows
around and in the power electronics device, and is then discharged to the
outside by the fan 16 through the flap 18. This enables the power electronics
device to be cooled.
If the power electronics device is on standby, the installation is configured as
described in the following with reference to figure 2.
In this configuration, the flap 12 is open, the flap 13 is closed, the fan 14 is off
and the flap 17 is closed. Moreover, the fan 11 can be activated with different
levels. So long as the temperature inside the first compartment is not too high,
the fan 11 can be off. It is switched on to prevent the temperature of the first
compartment from exceeding a threshold, for example 40°C. For this purpose,
it can be put into operation at different speeds. Likewise, so long as the
temperature inside the second compartment is not too high, the fan 16 can be
off. It is switched on to prevent the temperature of the second compartment
from exceeding a threshold, for example 40°C. For this purpose, it can be put
into operation at different speeds.
Thus, in the first compartment, air external to the enclosure is inlet via the flap
12, flows around the voltage converter, and is then discharged to the outside
by the fan 11. This enables the voltage converter to be cooled. In the second
compartment, air external to the enclosure is inlet via the opening 15, flows
around the power electronics device, and is then discharged to the outside by
the fan 16 through the flap 18. This enables the second compartment to be
cooled only if the temperature in the second compartment becomes too high.
In step 120, it is tested whether the power electronics device is on standby or
in operation. If the power electronics device is on standby, the installation is
configured as described in the following with reference to figure 3.
In this operating mode it is necessary to maintain an acceptable temperature in
the enclosure, particularly near to the power electronics device. For this, with a
concern for efficiency, the invention enables the heat losses of the voltage
converter 7 of the first compartment 6, that remained connected to the power
grid, to be used to increase the temperature of the second compartment 3.
In this configuration, the flap 12 is closed, the flap 13 is open, the fan 14 is on,
the fan 11 is off and the flap 17 is open. The fan 16 is preferably off, but can be
used (for example at low speed) to force circulation of the air flow in the power
electronics device.
Thus, in the first compartment, air internal to the enclosure is inlet via the flap
13 from the second compartment, flows around the voltage converter and is
heated by the heat losses of the voltage converter 7, and is then discharged to
the second compartment by the fan 14. The air therefore then heats the power
electronics device 2. This enables the heat losses of the voltage converter to
be used to heat the power electronics device. A thermal coupling is thus made
between the voltage converter and the power electronics device.
In this configuration, to increase the efficiency of the installation, all the air
inlets (for example the opening 15) could be closed. At the level of the
discharge openings 18 and 11, overpressure valves are for example used.
If the power electronics device is on, the installation is configured as described
in the following with reference to figure 4.
In this configuration, the flap 12 is open, the flap 13 is closed, the fan 14 is off
and the flap 17 is open. Moreover, the fan 11 can be activated with different
levels. So long as the temperature inside the first compartment is not too high,
the fan 11 can be off. It is switched on to prevent the temperature of the room
from exceeding a threshold, for example 40°C. For this purpose, it can be put
into operation at different speeds. In the second compartment, the fan 16
and/or flap 17 are controlled so that the temperature of the air flowing around
the power electronics device is for example comprised between 0° and 20 °C.
To do this, the air flow extracted from the power electronics device is broken
down into two parts : a first part that enters via the opening 15, flows around
and in the power electronics device and is then discharged to the outside via
the opening 18 in an extracted flow; and a second part which flows in the
second compartment and then in the power electronics device, and is then
discharged into the second compartment via the flap 17 in a recirculation flow.
The mixture of these two flows thereby enables the power electronics device to
be cooled using the outside air, while at the same time preserving an
acceptable temperature for the components in the second compartment 3.
The temperature of the second compartment will depend on the equilibrium
between the extracted flow and the recirculation flow. To regulate the
equilibrium of these flows, three solutions can be envisaged.
A first solution consists in controlling opening of the flap 17 and therefore the
pressure drop at the level of the flap 17, the difference between the pressure
drop at the level of the flap 17 and the pressure drop at the level of the flap 18
fixing the recirculation rate.
A second solution consists in making the flap 17 from several elements,
opening of which is able to be controlled independently from one another.
Several regulation stages are thus obtained.
A third solution consists in opening the flap 17 and in controlling the speed of
the fan 16. The flap 17 being open and the flap 18 opening according to the
pressure prevailing in the hood, it is possible to make more or less air
recirculate according to the speed of the fan 16.
Thus, in the first compartment, air external to the enclosure is inlet via the flap
12, circulates around the voltage converter, and is then discharged to the
outside by the fan 11. This enables the voltage converter to be cooled. In the
second compartment, air external to the enclosure is inlet via the opening 15,
flows around and in the power electronics device and is then partially
discharged to the outside by the fan 16 through the flap 18 and partially forced
to recirculate in the second compartment and around the power electronics
device. This enables the power electronics device to be cooled while at the
same time preserving an acceptable temperature in the second compartment.
In other embodiments not represented in the figures, the hardware means
comprise a direct opening between the second compartment and the outside
of the enclosure as a supplement to the flow passing via the raised floor. The
hardware means can likewise have at least one direct opening between the
second compartment and the outside of the enclosure without the presence of
a raised floor.
Unless the context requires otherwise the word ‘comprise’, and variations
including ‘comprises’ and ‘comprising’ are intended to be inclusive rather than
exclusive. In other words, comprise (and variations) is to be taken to mean
include and not ‘consists only of’ unless the context specifically precludes this
interpretation.
