ADF P300

A goldmine in Kalgoorlie had found a way of extracting more gold from the excavated ore. This required pumping water from another location, and a large variable speed drive was installed to control the pump.

Based on harmonic calculations, one active harmonic filter of the type ADF P300-360/480 was selected for each of the three feeders.

As with most vessels, onboard space (and especially space available for an installation) is a valuable commodity. With the very small size of Fox Luna, Comsys faced the added challenge of providing an effective solution in tight quarters.

One of the main challenges was that the Svedala operation began in 1882. It is a complex process to turn a 150+ year old industrial site into a modern operation.

After experiencing sudden unplanned production stops, and worried about the risk of increased total voltage harmonic distortion on production, UNILIN explored implementing a power quality solution.

The task was very challenging due to the rapidly fluctuating load, and the many different load patterns that could occur width such a high number of welding machines.

To achieve compliance, TiZir supplied background information to Comsys so that they could conduct a sizing/assessment for them. Comsys then made a recommendation regarding which ADF Power Tuning solutions would be right for this scenario, and TiZir accepted.

With the multiple generators and drives online, the electrical load is heavy and demanding — creating a need for a filter solution that will continuously track the load and adapt, in all operating conditions.

It is extremely important to meet regulatory standards in the offshore industry, and with ADF Power Tuning, Rowan Gorilla VI not only meets today’s standards, it goes beyond that.

While the Max Lab IV modulators would be unaffected without compensation, neighboring industries and residences and the Max Lab IV facility itself would be impacted with electrical disturbances, machine tripping, and equipment breakdown due to the unstable power supply.
