RELIABILITY AND QUALITY IN
POWER GENERATION
The growing strength of the Mitsubishi
Brand name: MITSUBISHI MGS series DIESEL GENERATOR SET
The core of the MGS Gen Set is now -S typed diesel engines for MGS Power Rating
•MITSUBISHI DIESEL ENGINES
Ranging in capacity from 0.5 to 56,400 horsepower, Mitsubishi brand diesel
engines offer a series of versatile power generating systems. Mitsubishi
Heavy Industries, Ltd. has continually introduced upgraded its engine
products since the inception of business in 1917, and now the MITSUBISHI MGS
series DIESEL GENERATOR SET provides a higher generating power rating and
more advanced control systems than ever before, with proven reliability
based on the continued research and development.
The best performance-matched engine system configured with Mitsubishi diesel
engines and Mitsubishi turbochargers, which are engineered and manufactured
in the same facility, is certain to result in the high productivity and
improved fuel economy in the MGS Power Generation. Every unit is inspected
and tested before leaving the factory and the test report is sent with the
Gen Set. MITSUBISHI MGS - All Mitsubishi assembled, tested and supported.
DEPENDABILITY & DURABILITY IN POWER GENERATION
The best performance-matched engine and generator systems give
world-class performance
Response and stability designed to exceed user expectations in a variety of
applications
•AC GENERATOR
4 pole, screen protected, drip-proof IP23, self-exciting, self-regulating
and brushless with fully connected damper windings, salient pole rotors, A.C.
exciter and rotating rectifier unit. The insulation system is Class 'H'. All
windings are impregnated in either a triple dip thermo-setting moisture, oil
and acid resisting polyester varnish or vacuum pressure impregnated with a
special polyester resin. Electrical design in accordance with BS5000 Part 3,
VDE0530, UTE51100, NEMA MG1-32, CEMA, IEC34-1, CSA22.2 and AS1359.
6 and 12 wire*1 reconnectable windings provide a wide range of 3
phase voltage. The exciter field system remains at full strength, sustaining
a high level of short circuit current at the ac generator output terminals
by means of the excitation voltage via AVR powered by the independent
winding, Permanent Magnet Generator (PMG) as a standard feature in the MGS
Gen Set, which is electrically isolated from the main alternator stator
windings.
The fully sealed, three phase*2 RMS voltage sensing AVR maintains
the voltage within the limits of +/-0.5%*3 from no load to full
load including cold to hot variations at any power factor between 0.8
lagging and unity allowing for a 4% engine speed variation, suitable for
applications with greatly unbalanced or high non-linear loads associated
with UPS systems. The AVR has built-in protection against sustained
over-excitation, caused by internal or external faults. This de-excites the
generator after a minimum of five seconds. THF (as defined by BS4999 Part
40) is better than 2 % and a TIF (as defined by ASA C50.12) is better than
50. Radio interface: Suppression is in line with the provision of BS800 and
VDE Class G and N.
| Note: |
*1 |
12 wire reconnectable windings are the features up
to Code H6 models. |

*2, 3 |
Up to Code K5 models have single phase voltage
sensingand the voltage regulation within +/-1.0%, for 4% engine
speed variation. |
Turbo-filter is standard and paper element dry type air-cleaner is available
as an option.
ADVANCED SOLUTION IN POWER GENERATION
"Full-sized" safety and automatic functions in the series of
digital control systems
Easy human interface in the sophisticated control system makes for an
operator-friendly Gen Set
•MGS series CONTROL PANEL
MGS standard Microprocessor control - automatic start/stop panel, indication
of the operational status and fault conditions; automatically shutting down
the engine and indicating the engine failure by means of a graphical LCD
display and flashing LED on the front panel. Electrical design in accordance
with BS EN 60950 Low Voltage Directive, BS EN 50081-2 and 50082-2 EMC
Directive. The optional interface can provide real time diagnostic
facilities.
