АДФ Смањује треперење на Хенрад НВ (ЦОМСИС АБ)

Todays industry constantly faces new challenges. When society expands in Herentals, Belgium, Henrad was faced with the challenge to reduce their flicker emission level in order to not disturb other industries on the public grid

“Comsys provided the most advanced and
cost efficient solution at the same time!"
– William de Winter, General Operations Manager, Henrad

“We at Laborelec conducted the reference measurements prior to and after the installation – the solution is approved.”
- Michele de Witte, Laborelec

Позадина

Henrad is a Belgian radiator manufacturer in the Caradan Group. The 55000 square meter factory in Herentals, Belgium consists of six production lines that totally can produce about 5000 радијатори дан. The production process are presses, шав заваривање и тачкасто заваривање, the nature of the process is very energy demanding and therefore puts great demands on the power grid. This together created large voltage drops in the feeding substation with the result of to high Pst values which would lead to flashing lights when Eandis, the local utility company, would connect other consumers to the same transformer.

Изазов

Локална комунална компанија захтевала да пст 95% value must not exceed 0,7. Измерене вредности током 2009 provided by the well-known Belgian consultancy firm Laborelec showed tops in the Pst equivalent to 1,6. The task was very challenging since it’s a rapidly fluctuating load and also the many different load patterns that could occur since its very high number of welding machines.

Кључне предности | Welding – Треперење:

  • Пст смањен са 1.6 до 0.63
  • Only solution with desired flicker mitigation performance without integration with welding lines – easier to instal
  • Fully autonomous solution – will work with future production line upgrades
  • Integrated with existing passive compensation system

Solution –
the ADF P300 Active Filter system

Henrad chose to invest in the ADF P300 Active Filter system, a well proven solution. The market leading response time was a necessity for the customer to reach the values that the utility company demanded. The system totally consists of six P300 units, што укупно 2,1 Мвар континуирано моћ да се надокнади падова напона.

Резултат, after installing the ADF Active Harmonic Filters

After installing the ADF Active Harmonic Filters Henrad has managed to keep their Pst value below 0,63 regardless of how many welding lines that are running. The reference values has been measured by Laborelec and approved by Eandis. Као споредни ефекат спуштена треперења вредности Henrad has also seen stabilized production environment.
