1000V Variable Speed Drive (VSD)
GP-1000-E 1000V (VSD) Variable Speed Drive
SMEC’s 1000V (VVVF) Variable Speed Drive utilises three-level control to offer the best solution for challenging installations. This innovative three-level control reduces motor winding stress, decreases electrical noise, and minimises drive-induced problems associated with long motor cables and premature motor bearings failures.
Using Variable Voltage, Variable Frequency (VVVF) technology has revolutionised ventilation efficiency, leading to enhanced sustainability and greater operational adaptability in underground mining.
SMEC’s innovative drive technology reduces motor winding stress by half, thanks to the VSD’s advanced three-level switching. This means longer motor life, reduced maintenance, and increased reliability – all leading to a healthier bottom line.
This results in significantly lower insulation stress, reduced shaft voltages, and the ability to use larger motors with standard bearings.
Figure 1 below shows a comparison between three- level and two-level voltage waveforms, with the three-level producing a significantly improved sinusoidal curve (waveform).
SMEC’s custom in-house designed and built enclosures house the 1000V Three-Level VSDs. Enclosures are built specifically for harsh conditions and high ambient temperatures typical in underground mining and tunnelling environments.
Standard 1000V VSD Enclosures include an inline reactor and DC Bus chokes for harmonic mitigation.
Local and remote control of the 1000V VSD panels is via an HMI unit. The HMI unit additionally provides local and remote access to the VSD control firmware, allowing VSD control parameters to be monitored remotely.
This versatile solution is perfectly suited for mining and underground operations, industrial processes, HVAC systems, and renewable energy applications. It enables a smooth motor start-up by gradually ramping up voltage and frequency, ensuring a soft start while optimizing performance to meet specific application demands.
