GH180 — Siemens SINAMICS GH180 Medium-Voltage Drive
The Siemens SINAMICS GH180 is a medium-voltage variable speed drive covering 2.3 kV to 13.8 kV and power ratings from 250 kW to over 100 MW, engineered for the most demanding pump, fan, compressor, and mill drive applications in oil and gas, petrochemical, mining, and power generation industries. The GH180's multilevel neutral-point clamped (NPC) inverter topology produces a near-sinusoidal output voltage waveform with total harmonic distortion (THD) below 2% — eliminating the need for an output transformer or sinusoidal filter and enabling direct connection to standard medium-voltage motors without derating or additional insulation requirements. This transformer-less topology also achieves efficiencies exceeding 97% across the load range, representing significant energy savings at the scale of MV pump and compressor applications.
The GH180 supports full four-quadrant (regenerative) operation for applications requiring active power return to the supply — such as oil pipeline pump trip-out scenarios and mine hoist lowering duty — and can be delivered in both voltage source inverter (VSI) and active front-end (AFE) configurations. The drive is engineered to comply with Saudi Aramco's SAES-E-301 engineering standard for variable speed electrical drives and the IEC 61800 series of adjustable speed drive standards. PROFINET communication provides integration into SIMATIC PCS 7 and SCADA systems, while redundant control boards and internal diagnostics provide the fault-tolerant architecture demanded by continuous-process operations that cannot tolerate unplanned drive shutdowns.
In Saudi Arabia, the SINAMICS GH180 KSA is deployed at SWCC and MARAFIQ desalination high-pressure pump drives where seawater reverse osmosis membranes require precise flow control at MV motor power levels exceeding 1 MW per pump, at Aramco crude oil pipeline booster pump stations where efficient variable-speed operation of 33 kV-supplied motors reduces pipeline operating costs, and at SABIC petrochemical plant large centrifugal compressor drives where the near-sinusoidal output voltage eliminates motor derating and harmonic filter cost. The Kingdom's growing mining sector at Ras Al-Khair and Wa'ad Al-Shamal uses the GH180 for ball mill and conveyor drives.
Razz Middle East provides SINAMICS GH180 project engineering, supply, installation supervision, and commissioning across Saudi Arabia, including MV cable and transformer co-ordination, protection relay interface design, and PROFINET DCS integration.

Key Features & Benefits
- Multilevel NPC topology produces output voltage THD below 2% — equivalent to direct mains quality — enabling direct connection to standard MV motors without derating, output filter, or special motor insulation.
- Efficiency exceeding 97% across the operating load range provides substantial energy savings for continuously running MV pump and compressor drives at Saudi petrochemical and desalination facilities running 8,000+ hours per year.
- Transformer-less topology eliminates the output transformer cost (typically 5–10% of total drive system cost for competing topologies), providing a lower total installed cost for MV drive systems in the 2.3–6.6 kV range.
- Four-quadrant regenerative operation returns braking energy to the MV supply for applications such as mine hoist lowering, pipeline pump runback, and large fan coast-down deceleration, reducing total site energy consumption.
- Redundant control electronics with dual control boards and automatic switchover maintain drive availability during control board component failures, preventing unplanned process shutdown at critical continuous-process Saudi facilities.
- PROFINET integration with SIMATIC PCS 7 and WinCC SCADA provides drive speed, power, fault, and diagnostic data directly to the plant DCS without additional communication gateways, simplifying the process control architecture.
- Saudi Aramco SAES-E-301 compliance documentation and type testing available, satisfying the engineering standard requirements for variable speed drives at all Saudi Aramco upstream, downstream, and pipeline facilities.
Industrial Applications in Saudi Arabia
- SWCC desalination high-pressure seawater reverse osmosis pump drives at Red Sea and Gulf Coast plants, where the GH180's precise flow control and direct MV motor connection at 3.3 kV enables efficient multi-MW per-pump variable speed operation.
- Crude oil and product pipeline booster pump drives at Aramco pipeline stations across the Kingdom, where 33 kV-supplied variable speed pump drives reduce pipeline hydraulic energy consumption by 20–40% at part-load flow rates.
- SABIC petrochemical centrifugal compressor variable speed drives at ethylene and propylene plants in Jubail, where the near-sinusoidal output voltage eliminates motor derating and the 97%+ efficiency exceeds fixed-speed motor efficiency.
- Ball mill and SAG mill main drives at phosphate and mineral processing at Ras Al-Khair industrial city, where the GH180's four-quadrant operation handles the regenerative torque events during controlled deceleration of high-inertia grinding mills.
- Power station boiler induced draught and forced draught fan drives at SEC combined cycle plants, where MV VFD control of large ID fans replaces inlet guide vanes, reducing fan auxiliary energy consumption by up to 60%.
- Steel rolling mill main drives and descaler pump drives at Hadeed Jubail, where the 4-quadrant regenerative capability recovers runout table deceleration energy to the 6.6 kV bus, improving overall rolling mill energy efficiency.
- Water injection pump drives at Aramco enhanced oil recovery facilities, where variable speed control of 6.6 kV injection pump motors maintains precise wellhead injection pressure profiles across changing reservoir conditions.
