Success stories:

Grid code compliance by mitigating flicker and voltage drop with STATCOM in an electric arc furnace

The operation of an electric arc furnace in a Russian steel plant was creating power quality issues such as flicker and voltage variations. The operation of the 6-ton DC arc furnace was not only disturbing the grid but also other customers in the neighborhood.

Success stories:

Improving productivity and power quality at a gold mine with STATCOM

One of the largest gold mines in Africa faced several power quality issues in the winder operation. Voltage fluctuations and harmonic distortions would require additional diesel gensets to be made operational. At times these power quality challenges have led to unexpected production downtime.

Success stories:

Better weld quality by reducing flicker and load unbalance with real-time reactive power compensation

Reactive power demand was fluctuating rapidly during a 120ms welding cycle in a Russian industrial plant. Conventional capacitor banks were too slow to respond to fast fluctuating reactive power demands. The resulting flicker was experienced even by other customers connected to the same bus.

Success stories:

Addressing power quality issues created by dynamic loads in a hospital to comply with harmonic distortion limits defined in G5/4

One of the largest hospitals in the UK was facing problems created by significantly high current and voltage harmonic distortions. The burning of expensive electronic cards and the synchronization of mains and standby generators became challenging.

Success stories:

Mitigating harmonic distortions produced by 6-pulse variable speed drives at a waste water treatment plant

Reliable operation of a waste water treatment plant in the Asia Pacific region was the prime objective of design consultants. To ensure that harmonic distortions remain below the limits specified in IEEE 519 – 1992, design options for 6-pulse variable speed drives with active harmonic filters and active front end (AFE) drives were evaluated.

Success stories:

Current and voltage distortion to meet IEEE 519 – 1992 limits in a district cooling plant

A large commercial complex in the Middle East was fed with 11 diesel generating sets of 1.6MW each. The main loads at the district cooling plant were centrifugal and the absorption chillers were being fed by AC drives. The short-circuit level was low at 13.5kV bus.

Success stories:

Smooth operation of a large compressor in a chemical plant by bringing total harmonic distortion (THD) below IEEE 519 – 1992 limits

Large compressors in an Asian chemical plant were being fed by high power variable speed drives (VFDs). The operation of the drives was causing high harmonic currents up to 35%. A number of individual harmonics were found high, e.g. 5th, 7th, 11th and 13th, in the case of the 5th and 7th very high, and needed to be mitigated.

Success stories:

Active harmonic filtering to ensure reliable operation of a printing press to comply with the limits specified in G5/4

A major UK printing press operated under a number of non-linear loads. One of the loads was a large UPS feeding the press, IT and newsroom offices. A power quality audit revealed voltage harmonic distortions as high as 8%.

Success stories:

Cancellation of triplen harmonics to smooth critical processes in a stock exchange

One of the largest stock exchanges in the world comprises of several single-phase non-linear loads. The presence of such loads in the electrical system generated high harmonic current distortions. Total distortion would be as high as 30 %, well above the limits defined by the local regulatory body.

Success stories:

Filtering harmonic currents of DC drives and improving process reliability in an adventure park

Rides in a large adventure park in Finland were fed by DC drives. The drives were causing power quality problems such as harmonic distortions, voltage fluctuations and commutation notches. Problems were particularly high on certain rides fed with DC drives.
