Powersystems Attend Parliament

Powersystems were invited to attend the houses of parliament this week with the Conservative Environment Network, Vattenfall and 10:10 Climate Action Group, to talk with MP’s and constituents about the cheapest source of electricity generation: onshore wind.

There is currently 5GW of onshore wind projects with planning consent ready to be built and the key message was that by excluding onshore windfarm from future Contracts for Difference auctions this pipeline is unlikely to be realised.

With Powersystems responsible for the electrical installation on over 25% of onshore wind farms in the UK we are a trusted supply partner and best placed to speak with MP’s about the important role wind generation plays in keeping the lights on, reducing bills and its significance in fighting climate change. The event was opened by Simon Clarke MP and other speakers included Luke Graham MP and Sam Richards of CEN.

A fantastic turnout of 40 MP’s showing there is a real interest in making a difference.  Also a great opportunity for Powersystems to speak with likeminded people on the importance of onshore wind in the UK. We would like to thank our local MP Luke Hall for dropping in to lend his support.

Did you know that 66% of onshore wind investment stays in the UK economy –  therefore supporting it could create 18,000 construction jobs and a further 8,500 long-term O&M jobs!

Powersystems UK, Now Powered By Partners

Powersystems UK, Now Powered By Partners

Powersystems UK Ltd are pleased to announce that as from 2nd January 2019 we are now an employee owned business. This marks a new chapter in the history for Powersystems UK and ensures a continuing legacy for the company based upon its original founders engineering ethos and family values. This positive step will further empower all employees in ensuring the business continues to flourish delivering high quality and engineering excellence within the High Voltage sector.

The employee owned business (EOB) follows a similar model to that of the John Lewis Partnership with all employees of Powersystems becoming “Powersystems partners”. This model will ensure the long-term stability of the company ownership and be a driver for greater performance and productivity throughout the business.

Chris Jenkins will take over the Managing Director role from Stuart Wilsmore who will remain on the company board along with founding partner Derek Earby as a non-executive Directors.

Chris comments:

“I am honoured and privileged after 25 years with the company to take on this role and lead us all forward as an employee owned business. This change in ownership will only strengthen our culture and ensure we achieve our vision of being recognised by industry and clients as the high voltage specialist contractor of choice across the UK”.

Powersystems UK’s participation in the renewable energy sectors continues with growth in grid connections, industrial power sectors, STOR & battery projects. With the emergence of new technologies and markets such as electrical vehicle charging (EV) , Powersystems is looking forward to an exciting future for our business.

Christmas is here again and at Powersystems UK we look back on another successful year with customers both existing and new.

2018 brought about continued success on major UK renewable schemes, contributing to a greener national grid with the energisation of large projects such as Blackcraig and Dorenell windfarms in Scotland. Alongside works within renewables, Powersystems has worked on significant projects within the UK private industry sector, supporting prestigious and well-established UK companies. We look forward to continued successful collaboration going into 2019, with some exciting changes ahead!

To ensure continued service during the Christmas period, our head office will be open, however we will be closing at midday on Friday 21 December for festivities with our staff to celebrate another successful year re-opening on 27 December. We would like to thank our customers and suppliers for your support this year.

Wishing you all a very Merry Christmas and a prosperous and busy 2019!

Powersystems UK have now handed over Blackcraig Windfarm. Powersystems UK supported the customer by installing, commissioning and back energising the site with a Generator System to enable the Turbine supplier, Siemens Gamesa, to commission a turbine against a ‘false grid’.  The HV Generator system comprised of a step-up transformer to energise the system at 33kV, a main and backup generator to ensure continuity of supply and to provide stability during energisation of the turbine transformers, 2MW of load banks to provide load for the turbine to generate against and LV switched inductor banks to compensate for the reactive power due to cable capacitance on the site.  All controlled with an integral  Modbus controller to automatically switch the load bank load.  Commissioning was successful and completed in the short timeframe required. The site was then transferred to the new grid supply and was immediately online and available to generate through the meter, a pre-requisite for the customer Blue Energy in compliance with the Ofgem accreditation criteria.

Energy Now Expo 2018

Dedicated to renewable generation, Energy Now Expo at Telford International Centre brings together landowners from across the country to speak to experts in the field. Powersystems are pleased to be a part of the show, showcasing our expertise in high voltage electrical engineering to visitors. On site, at stand 11, we are pleased to have some of our top experts to discuss everything from grid connections to renewable energy generation.

Successful Point-on-wave Energisation of 90 MVA Transformer

Successful Point-on-wave Energisation of 90 MVA Transformer

Powersystems have successfully energised a 90 MVA transformer using new point-on-wave technology to limit the inrush current and voltage dip.

Community Windpower engaged Powersystems to build the electrical connection for Aikengall II Wind Farm, a new 60.8 MW wind farm located in East Lothian. As part of the connection works Powersystems provided a 90 MVA 132/33 kV transformer. However, initial simulation studies showed that energisation of the transformer would cause significant voltage dips of up to 18% on the 132 kV grid.

To reduce the inrush current and voltage dip, Powersystems’ engineers recommended installing a 132 kV circuit breaker with segregated phase switching in conjunction with a point-on-wave controller which controls the precise time that each phase is closed.

Inrush current can be reduced and virtually eliminated by closing each phase at the precise moment in time when the voltage waveform from the supply side matches the remanent flux that is left in the transformer. Powersystems used a 132 kV circuit breaker supplied by GE Grid Solutions in conjunction with a Visimax SynchroTeq Plus supplied by Enspec Power to measure the transformer remanent flux and control the closing time.

The SynchroTeq Plus performed remarkably. By the completion of commissioning, the voltage dip on the 132 kV system had been reduced from about 7% during an uncontrolled energisation of the transformer, to 0.6% when energisation was controlled by the SynchroTeq Plus.

This is the first 132 kV transformer in the UK to be controlled by the SynchroTeq Plus and these results show that point-on-wave control technology is now a viable option for mitigating transformer inrush currents even for large grid-scale transformers.
