GROWING WORLDWIDE

The rapid speed of change in our daily world requires constant adaption. Companies need to incorporate within its organization the culture for continuous change if they want to survive in an ever increasing competitive world and adapt to the market needs.

Customer orientation and flexibility are a motor of change at Power Electronics. We are continuously monitoring our customers to identify new needs, find out solutions to their challenges and standardize them in a very brief timeframe. This process requires a highly skilled and motivated staff, involved in our long-term project, with a versatile and multidisciplinary professional profile, and a total understanding and acceptance of continuous adaptation as the only one way to succeed in our market.

It is through the internalization of this culture alone that Power Electronics has succeeded in becoming a multinational market player, able to improve its corporate image, release new products, open up new branches in three different continents or triple its production capability within one year.

During 2012 we will finish the completion of our new corporate image with the renewal of all our corporate and product literature. We have already released an IP65 central solar inverter and our range of low harmonics variable speed drives. A transformerless solar inverter is yet to come. India, South Africa, Colombia and Peru will be a reality in the fourth quarter and a new production plant for MV Variable Speed Drives and Soft Starters and solar inverters will be inaugurated in the third quarter.

And this is only the beginning…

OUTSTANDING PERFORMANCE OF THE POWER ELECTRONICS ASPAR TEAMHalfway through the MotoGP World Championship, the POWER ELECTRONICS ASPAR TEAM leads the CRT standings with the racer Randy de Puniet in the first position and Aleix Espargaró in the second one only separated by two points and with a comfortable gap with regard to other CRT motorbikes.

After a hard beginning in Losail (Qatar), Jerez (Spain), Estoril (Portugal) and Lemans (France), where results were not really convincing and Randy de Puniet could only finish two of these Grand Prix, POWER ELECTRONICS ASPAR TEAM has managed to develop the motorbikes making them more competitive and easy to drive. From the Catalonia GP (Spain) till the last one held at Mugello (Italy), our two bikes scored in every single Grand Prix with some outstanding results such as the eighth place of Randy de Puniet at Assen (Netherlands), a circuit which is worldwide known as the “Cathedral of Motorcycling”.

The second half of the MotoGP World Championship promises to be really exciting for the POWER ELECTRONICS ASPAR TEAM. Motorbikes, with the inestimable support of all our engineers, are rapidly shortening the gap with the official motorbikes, which will lead to surprising results in the second half of the Championship.

NEW VERSION OF THE POWERCOMMS SOFTWAREAn easy to use tool to monitor and control any Power Electronics device

The latest version of the PowerCOMMS tool has been just released. PowerCOMMS is a very powerful desktop based tool mainly used to monitor and control Power Electronics variable speed drives, softstarters and solar inverters in a network. This new version offers the possibility to configure specific projects and add as many Power Electronics devices as necessary.

Variable Speed Drives, softstarters and solar inverters can be monitored via PC with a RS485/R232 cable or through Ethernet. One important feature is that PowerCOMMS allows a dynamic DNS, a method of updating in realtime DNS when it is about to point to a changing IP address on the internet. This way it is possible to use a unique domain whereas the IP is not unique.

PowerCOMMS also enables to

import any configuration in a DCF format and export it to any other devices, which require the same configuration. It is also possible to import data in a xls file.

Another important improvement from the previous version is the Data logger. Users can now configure, monitor and obtain graphics from up to ten different magnitudes in real time with data registers in a minimum

interval of 200 milliseconds. In case of trip, once the different magnitudes have been configured and a start command has been given, the user can get a full feedback of any

eventuality under which, the drive tripped and also further information after the drive was reseted. For instance, visualization parameters such as energy consumption, regenerated energy, motor voltage, PTC motor temperature, IGBT temperature, motor overheating…etc, can be monitored.

PowerCOMMS also guarantees a total control of the drive. Order, stop or reset commands can also be remotely configured from a PC.

With this tool the user can not only monitor any Power Electronics device but also remotely control and commission them. It is a user-friendly and flexible tool used to copy and save parameters remotely, speed up commissioning or settings and monitor key magnitudes for the electronic devices and the application.

Powercomms will enable the monitoring up to ten different magnitudes in

real time

Companies operate in a highly automated world with an intensive use of power electronics devices. In order to operate, these devices are installed in a sensitive environment that could cause systems malfunction due to electric distortions. These distortions are called harmonics and are responsible for the generation of problems such as transformer and grid overloads, electric losses, resonance or instrumentation imprecision. The increasing use of Variable Speed Drives in industrial and domestic applications, together with the use of non dimensional capacitors for the improvement of the power factor have widespread the “harmonics problem”.

Power Electronics, aware of the increasing importance of harmonics in industrial facilities and the entering into force of more restricting legislations worldwide, has developed the FREEMAQ solution within its SD700 range of Variable Speed Drives complying with the IEEE519, a Standard for the harmonics control in power electronics systems.

Within our FREEMAQ solution we offer two low harmonics alternatives:

SD700 FREEMAQ LOW HARMONICS DRIVESHarmonics are no longer an issue!

SD700FL SERIES LOW HARMONICS NOTCH FILTER

SD700FL is based on a Notch input filter technology included in an input filter cabinet under the supervision and control of the Variable Speed Drive. It is a robust solution that meets the THDi requirements keeping SD700 features.

What are the main differences between our FL solution and the use of a standard passive filter?

In the case of our SD700FL solution, the filtering capability does not depend on the grid impedance, that means that the filter will never cause resonance as a standard passive filter may does, and its performance will not vary significantly after any electrical grid variations. This is the main feature, which makes it suitable for any low harmonic application.

A standard passive filter is usually a LC filter designed specifically to filter the 5th and 7th harmonics for a specific grid configuration and impedance. If the grid impedance changes due to the introduction of

new loads or motors, the filtering capability changes and may cause a resonance effect in the worst case. In our SD700FL solution, the Notch filter integrates a line impedance, which makes the grid impedance

insignificant. Therefore, the variation of the grid impedance does not affect the filtering capability. We design long lasting drives to meet nowadays and future needs.

Moreover, the SD700FL is a fully tested solution, so there is no need to install any independent passive filter. SD700FL is a truly tested solution, customized to meet the specific needs of any application. The Variable Speed Drive monitors the temperature and activates the integrated contactor of the filter to provide the best performance under any load condition.

The Active front end Technology also enables to have an electronic control of the cosine PHI or displacement power factor (DPF), which avoids the use of capacitor banks to correct it. In addition, the IGBT rectifier bridge enables the Variable Speed Drive to keep a constant DC bus voltage in case of any voltage dip. Even when high voltage drops occur, the Variable Speed Drive will supply the rated motor voltage.

The active front end technology can replace multi-pulse solutions and passive filters. Multi-pulse solutions have higher installation costs due to the need of special transformers and wiring requirements, no cosine phi control, higher input voltage drops and no regeneration capacity.

of cosine phi

TSD700FR SERIES LOW HARMONICS AND REGENERATIVE

SD700FR SERIES goes one step ahead keeping the family unique characteristics. Based on the last Active Front End Technology the Variable Speed Drive offers two main features:

The current rectifying bridges equipped with thyristors-diodes are replaced by an Isolated Gate Bipolar Transistor (IGBT) bridge. This allows that current flows in both directions, from the grid to the motor and on the reverse direction. In regenerative applications, where the motor operates as generator, the braking energy can be supplied back to the network with the corresponding energy saving. With the old technology the energy generated by the motor was dissipated as thermal energy through braking resistors.

Thanks to the use of the AFE technology and an LCL filter, the Variable Speed Drive brings the THDi below 5%, that complies with IEEE519.

NEW FREESUN HEC SERIESAn IP65 solar inverter unit without Medium Voltage grid connection

This new outdoor inverter will result in a cut of wiring,

installation, handling and transport costs

Freesun IP65 HEC series 1MW

Power Electronics just released the solar inverter FREESUN-HEC. This is an outdoor version of our FREESUN-HE central inverter series. Its main feature is that it can be installed outdoor without any additional cost due to its IP65 protection degree, which enables the internal side of the inverter to be fully sealed and protected from any external environmental conditions. All the structure and doors are made of stainless steel and all the external mechanical parts are painted with a special durable paint, which is guaranteed for 12 years. Furthermore, all the structure of the modules, which make up the central solar inverter are also treated. They are all zinc coated and painted to improve its protection against external agents.

With the release of the FREESUN-HEC we have managed to slightly reduce the cost of wiring and installation as the handling is much easier and cheaper due to the fact that there are not big cranes involved in the unload. On the other side, we have managed to design a compact structure, which minimizes the transport costs letting the medium voltage side for grid connection to be arranged locally.

FREESUN-HEC also offers all the technical features of the HE SERIES, which make it a unique central solar inverter. It has also been designed under the ARM2S2 TECHNOLOGY (Automatic, Redundant, Modular, Master-Slave System), which goes a step ahead by automatically bypassing and restarting the inverter without production losses. The main features of this brand new technology are:

AUTOMATIC The inverter automatically calculates and establishes the master module considering the total injected power of every slave module at night. Therefore we manage to homogenize the service life of all the components. In addition, the inverter is automatically restarted immediately after a fault occurs. The faulty module is bypassed and the inverter continues to operate without production losses.

REDUNDANT

The inverter is made up of equal modules, which are composed of the same components. Any module can operate as a master module, so in case of failure of the master module, the inverters will automatically assign another module as master.

MODULAR

The power of the inverter is build up out of 100 to 139kW equal modules, depending on the output voltage.

MASTER-SLAVE

One module operates as master and the remaining modules as slaves. They are all communicated through fiber optics.

Conveyors are one of the most common applications in a wide variety of sectors, from the simplest conveyor systems used in the food industry to the most complex belt conveyors used in mineral extraction and processing plants, which are suitable for the transport of minerals throughout the different stages of the whole production process.

These belt conveyors usually integrate two or more traction motors and operate in the harshest environmental conditions, with a high level of dust and humidity. SD700, which has specially been designed to operate under these extreme conditions, adds the so called

POWER MOTOR CONTROL (PMC), a dedicated software exclusively used for the movement and transport of minerals and other stuff in high polluted environments. Both the SD700 mechanical design and the PMC control system facilitate that the motors supply a better dynamic response, taking advantage of external mechanical braking systems and avoiding high maintenance and low reliability systems such as motor encoders.

The deep know-how of our software engineering department at Power Electronics in a wide number of industrial applications have resulted in the development of a simple,

The example illustrates the traction of a Conveyor with two direct coupled motors. VSD A is set up as master and VSD B as slave and it will be responsible for balancing the torque between both motors. This way both motors maximize their performance and increase their service life as both wear out homogeneously. PMC control and the use of fiber optics enable long communication distances between both variable speed drives without any interference in the most aggressive environments.

robust and precise motor control software. SD700 variable speed drives incorporate as standard a V/Hz control and a vector control (Power Motor Control (PMC) and Advanced Vector Control (AVC)). PMC-OLTQ (Open Loop Torque Control) is a unique system exclusively developed for the control of multiple variable speed drives, whose motors supply traction to a single belt conveyor or share the axis without any encoder. Variable Speed Drives are communicated through fiber optics without the need to install an encoder, which reduces the maintenance cost of any facilities and speeds up commissionings and settings.

PMC has multiple advantages :

• Loaded startup and stop of transport systems without any backing down.

• Productivity increase of any transport system with a frequency supply over 50hz.

• Maximization of motor and variable speed drive performance without an overload.

• On load smooth startups withoutover-current and voltage drops.

• No auto tunning needed.

• High torque at low speed.

• Noise immunity due to the communication through fiber optics.

• The performance of the motor is constant, no matter if conditions change.

• Controls external Mechanical brakes without additional manoeuvre.

Based at Tiwai Point, near Bluff, New Zealand Aluminium Smelters Limited (NZAS) is New Zealand’s only Aluminium smelting operation. The plant, which is part of the Rio Tinto Alcan Group, produces around 360,000 tonnes of aluminium per year, of which around 90 per cent is exported to customers in Asia, Europe and the USA.

As New Zealand’s single largest electrical consumer, using about 15 per cent of the national energy production, NZAS is always focused on process optimisation, energy efficiency, and ensuring minimal impact on the environment. A recent upgrade project undertaken on the aluminium casting machines in the Metals Products plant is an excellent example of this commitment.

At NZAS, the casting machines are the mainstay apparatus for ingot, billet and rolling block production. To produce ingots, molten aluminium is poured into moulds and then cooled by passing the molten aluminium into a water bath or ingot coldwell. The optimum specification for the water temperature in the coldwell is extremely tight with a target of 23oC +/- 3oC.

The cooling water is a combination of water recycled from the process and make up water pumped directly from bores on site. Previously, control of the water temperature at the coldwell was achieved using a number of fixed speed circulating and make up pumps, and cooling towers fitted with fixed speed fans.

Eighteen pumps and fans, varying in size from 22kW to 55kW form the heart of the cooling system. A complicated PLC programme was used to stage the correct combination of pumps and cooling to keep the water temperature as close to specification as possible. With variables in the system such as ambient air temperature, ambient

water and bore temperature, and the digital nature of the operation of pump and cooling fans, this has always been a very difficult target to achieve.

The NZAS Metal Products engineering team spent a number of months evaluating the existing process and decided that this was the perfect application to change the control philosophy to be fully variable. SD700 variable speed drives were fitted to all the pumps and fans, and a new control system implemented.

Pre and post implementation case studies were undertaken by the NZAS team to quantify the benefits. The three major areas measured were:

Electricity usage and efficiency prior to implementation the Vertical

Direct Chill Casting and No. 2 ingot machine were both using 9100kW/hr per day. Post implementation the energy consumption has dropped a staggering 5140kW/hr per day to 3960kW/hr per day.

Make-up water usage in 2007 the VDC and No. 2 ingot machine used 220,000,000 litres of water. 2010 year to date (five months) the same machine has used only 45,000,000 litres of water. At this rate of consumption the total yearly water usage will be less than 50 per cent.

Pump start-ups some of the pumps have been starting up to 39 times per hour during periods of casting. This has been reduced to less than 1 start per hour.

Don Faulkner from the Metal Products project engineering team comments, “The benefits of this plant upgrade have been phenomenal. We have seen improvements in all the areas that we expected and more. Obviously this has resulted in greater consistency in our finished product, significant energy savings, and a massive reduction in our make-up water usage. There have also been some hidden benefits as well. With the reduction in pump starts we have seen a massive increase in mechanical pump reliability. The project has been so successful that we are just about to embark on the second stage. We will definitely be using SD700 variable speed drives for this stage as well!”

Electrical consumption dropped a staggering 56%

and water consumption over 50%
