ZDDQ solutions for efficient and reliable operation of electrical systems under extreme conditions . Whether it comes to extraction, processing or transport, all of the processes concerning crude oil and natural gas are subject to the strictest standards in terms of operational safety, and necessitate a reliable, interference-free power supply. At the same time, at many locations both onshore and offshore, extreme environmental conditions are not uncommon. The Maschinenfabrik Reinhausen product range offers a variety of system solutions in order to ensure reliable, efficient and interruption-free operation under these difficult conditions. For example, MR provides reactive power compensation systems to improve the displacement factor cos phi, filter circuits for harmonics reduction, equipment for balancing non-symmetrical loads, dynamic compensation systems for voltage stabilization, and equipment for preventing transient voltage drops. Based on nearly 20 years of experience, ZDDQ already supports its customers during the planning phase of a new system, through tasks such as measurements and grid analyses.

Our typical projects Industry background Oil extraction and production facilities on offshore platforms face high temperatures, high pressures, high flammability, and high volatility, which demands a highly reliable, continuous, safe, and high-quality power supply. Offshore platforms require ongoing operations and power system failure for a few cycles can shut down a large amount of production equipment and cause catastrophic consequences, including unplanned shutdowns, industrial safety accidents, and pollution. Due to production needs, offshore oil platforms use a large number of pumps, and most pumps are equipped with VFDs. The use of many VFDs results in a significant increase of harmonic current in the distribution systems of offshore platforms. Six-pulse rectification is often used in the rectifier of VFDs to convert alternate current into direct current, which generally produce harmonics of the 5th, 7th, and 11th orders. Besides reducing the work efficiency of equipment, this type of harmonic load causes voltage distortion in circuit impedance and accumulates which weakens the entire grid and threatens distribution stability and all electricity loads.
