Diesel Power Plant Wartsila 50 MW with 6 x 20V32 HFO Generator Sets
The diesel power plant has a total installed capacity of 53.5 MW and
comprises six identical Wartsila 20V32 generator sets, each rated at
8.9 MWe (50 Hz). The generating sets are equipped with asynchronous
AKV alternators and are designed to operate on heavy fuel oil (HFO).
All necessary auxiliary systems are included.
Each engine operates at 750 rpm and is turbocharged with intercooling.
The engines are mounted on base frames that also function as wet oil
sumps. The generator sets have accumulated approximately 35,000 total
operating hours and have been maintained in accordance with
Wartsila’s service guidelines. Maintenance has been performed by
Wartsila Service and a certified service provider specializing in
Wartsila engines.
Engine cooling is provided by a radiator-based cooling system with two
separate cooling circuits. The delivery scope includes complete
mechanical and electrical systems for HFO operation and for power
dispatch at 132 kV / 50 Hz to the local grid. It has black start unit,
water treatment unit, exhaust gas steam boilers, auxiliary steam
boiler for start up and complete work shop tools.
All equipment is in good operational condition and can be demonstrated
under full-load conditions. The plant’s operating and engine control
systems are based on Wartsila WOIS and WISE platforms, with Modicon
Schneider PLCs. The electrical cabinets, including Siemens 11 kV VCB
(vacuum circuit breakers) and all motor control centers (MCCs), are
also supplied by Siemens.
