배경

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 하루에게 라디에이터. The production process are presses, 심 용접 및 스폿 용접, 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.

도전

지역 전력 회사가 요구하는 태평양 표준시 95% value must not exceed 0,7. 동안 측정 된 값을 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.

주요 혜택 | Welding – 깜박임:

  • 태평양 표준시로 감소 1.6 에 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 체계, 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, 그것의 전체 만드는 2,1 전압 강하를 보상하기 위해 지속적인 전력 MVAR.

결과, 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. 하강 플리커 값의 부작용으로 Henrad has also seen stabilized production environment.
