Motorisation of compressors in a colliery gas compression station
Client expectation
Replacement of 3 of the 4 combustion engines, each coupled to the 1200 kVa compressors by electric motors of comparable capacity, but with greater throughput, while at the same time rationalising and optimising the command and safety monitoring systems.
It will also be necessary to take into account the modification of the energy infrastructure in order to oversee the new motors from outside the production premises. Some of the equipment will be in the ATEX zone.
DV GROUP Solution
Turnkey solution from the client’s 15 kV HTA network to the end of the crankshaft.
Redesign of the HTA network with a new EDF-compatible station, 3 Schelters each equipped with an HTA protective panel, a double wrap 12-pulse 1600 kVa transformer, a 12-pulse 1350 kW driver from a command monitoring cupboard with ATEX instrumentation and a 1250 kW motor.
Work carried out
- 1 concrete post, HTA delivery, with a Schneider SM6 panel
- 3 Schelter 40’ HighCubes comprising a Schneider HTA panel (IM,QM), a GC Power 1600 KVA 15 Kv 690V double wrap transformer, the ventilation kit and interior equipment.
- 3 Siemens G150 1350 Kw 12 pulse 690 V cupboards
- 3 1250 kW D1LA4 motors equipped with vibration captors
- 3 robot S7 1511 1PN with ET200SP and Afficheur TP1200 Confort cupboards
- 3 Siemens instrumentation kits (differential pressure, relative pressure, temperature, flow sensor, level captor, ATEX barrier etc.)
3 Schelter 40’ HighCubes comprising a Schneider HTA panel (IM,QM), a GC Power 1600 KVA 15 Kv 690V double wrap transformer, the ventilation kit and interior equipment.
Clients gains and benefits
- The installation throughputs have gone from 50% to nearly 95%, with return on investment in under a year
- Controlled energy costs
- Increased installation availability
- Decrease in maintenance call-outs
- Production gains related to the 25% increase in productivity in comparison with combustion engines
- Facilitated maintenance through distance monitoring outside the Atex zone
